Find a Symbol You Can't Name

Looks like: A T-shaped cross topped with a teardrop-shaped loop, usually held by the loop in Egyptian art.

The Egyptian hieroglyph for 'life'. Gods are shown holding it to the nose of a king, offering the breath of life — so it reads as life, immortality and the vitality that outlasts the body.

Ancient Egypt, in use from around 3000 BCE.

Looks like: A stylised human eye with a heavy brow, a teardrop mark below it and a long curling tail to the side.

An amulet of protection, health and restoration — the eye Horus lost and had made whole again. Worn to keep the wearer sound and to guard what is fragile.

Ancient Egypt, widespread from the Old Kingdom onward.

Looks like: A dung beetle seen from directly above, often carved as a seal, sometimes with a sun disc between outstretched wings.

The beetle rolling its ball was read as the god pushing the sun into the sky each dawn, so the scarab stands for rebirth, renewal and the self-made new beginning.

Ancient Egypt, from the Middle Kingdom onward.

Looks like: Concentric rings — dark blue outside, white, light blue, then a black dot at the centre — like a staring eye.

A charm worn to absorb and reflect the envious glance. It does not wish harm; it stands guard against it, which is why it is hung on doors, cots and car mirrors.

Amulets against the evil eye are attested across the ancient Mediterranean and West Asia; the blue glass bead form is long-established in Turkey and Greece.

Looks like: A symmetrical open palm with a thumb on both sides, so it looks the same either way up; often with an eye in the centre of the palm.

A protective hand held up against harm and the evil eye. Called the Hand of Fatima in Islamic usage and the Hand of Miriam in Jewish usage — the same gesture, two names.

A hand amulet long used across North Africa and the Middle East.

Looks like: Bands woven over and under each other in a continuous loop, with no visible start or finish.

The unbroken line reads as continuity — an eternal bond, a life without end, or the way everything loops back into everything else.

Insular art of early medieval Ireland and Britain, roughly the 7th–9th centuries CE.

Looks like: Three pointed leaf shapes interlaced into a single knot, often with a circle threaded through them.

Three things held as one — read in Christian use as the Trinity, and in modern spiritual use as mind/body/spirit or maiden/mother/crone.

Worth knowing: The 'maiden, mother, crone' reading is modern; the medieval examples are decorative and Christian.

Found in Germanic and Insular art from the early medieval period, including the Book of Kells.

Looks like: Three spirals — or three bent running legs — turning out from one shared centre.

Motion that never stops. Read as the three stages of life, or as forward movement and personal progress that keeps returning and rising.

Carved at Newgrange in Ireland around 3200 BCE; later used in Greek and Sicilian art.

Looks like: A cross with a ring joining its four arms where they meet.

Christian faith rooted in an older world — the cross for the faith, the ring most often read as eternity, the sun, or the halo of light around it.

Irish and British high crosses, from about the 8th century CE.

Looks like: A tree whose branches above and roots below mirror each other, usually enclosed in a circle.

Everything connected to everything. Roots, trunk and crown as underworld, world and heavens — and, closer to home, family, ancestry and growth that holds on to where it came from.

A world-tree motif appears in Mesopotamian, Egyptian, Norse and Kabbalistic traditions.

Looks like: Two hands cupping a heart with a crown resting on top of it.

Hands for friendship, heart for love, crown for loyalty. Which way the ring is worn traditionally says whether the wearer's heart is taken.

Ireland, from the village of Claddagh near Galway; rings survive from the 17th–18th centuries.

Looks like: Groups of one to five notches and strokes cut across or beside a single long stem line, often read up the edge of a stone.

An alphabet, not a magic script — though each letter later became linked to a tree, which is why it turns up in modern nature spirituality.

Early medieval Ireland, roughly the 4th–6th centuries CE.

Looks like: A single line curling outward from — or inward toward — one point.

The journey that circles but never repeats. Growth, the return to the centre, and the sense that you are covering old ground at a new height.

One of the oldest carved motifs on earth; Neolithic examples at Newgrange date to about 3200 BCE.

Looks like: One winding path folded back on itself inside a circle — no branches, no dead ends, unlike a maze.

A walk, not a puzzle. You cannot get lost; you can only keep going, which is why it is used as a meditation on the way through a hard season.

The classical seven-circuit design appears on Cretan coins; cathedral pavement labyrinths date from the medieval period.

Looks like: A circle divided by an S-curve into a black half and a white half, each holding a small dot of the other colour.

Opposites that need each other. Neither side wins, and each already carries the seed of the other — the reason it is the standing image of balance.

Chinese; the familiar swirled disc form was popularised in the Song dynasty (11th century CE).

Looks like: A curved Devanagari character like a '3' with a tail trailing right, a crescent and a dot floating above.

The sound the universe is said to be made of, chanted at the opening and close of practice. Its curves are read as waking, dreaming, deep sleep and the silence beyond all three.

The syllable appears in the Upanishads, from roughly the 1st millennium BCE.

Looks like: A many-petalled flower opening on the surface of water, often shown with the petals fanned wide.

It roots in mud and opens clean. Purity that is earned rather than protected, and an awakening that needed the murk to happen at all.

Sacred in Egypt and in India from antiquity; central to Hindu and Buddhist art.

Looks like: A circle packed with repeating geometry — squares, gates and petals — radiating out from a marked centre.

A map of a whole world, and of a whole self, with the still point at the middle. Made to be entered with the eye, which is why colouring one settles the mind.

Hindu and Buddhist ritual art; sand mandalas are a long-standing Tibetan Buddhist practice.

Looks like: A wheel with a hub, a rim and eight spokes.

The teaching set in motion, with the eight spokes for the Eightfold Path — right view, intention, speech, action, livelihood, effort, mindfulness and concentration.

One of the earliest Buddhist symbols, in use by roughly the 3rd century BCE.

Looks like: A single eye set upright in the middle of the forehead, sometimes drawn inside a two-petalled circle.

Seeing past what the two eyes report — intuition, insight and the quiet knowing that arrives before the reasoning does.

The ajna chakra of Hindu tantric tradition; marked on the brow in art and practice.

Looks like: A loop of beads — 108 on a mala, 99 on a misbaha, five decades on a rosary — usually with one larger bead or tassel marking the start.

The hand keeps count so the mind doesn't have to. Devotion made physical, one bead at a time.

Counting beads are used in Hindu, Buddhist, Christian, Islamic and Baháʼí practice; the Hindu and Buddhist mala is the oldest documented form.

Looks like: Seven stacked discs, each a lotus with a different number of petals and its own colour, running from the base of the spine to the crown.

Seven gates for energy in the body — root for safety, sacral for feeling, solar plexus for will, heart for love, throat for truth, brow for insight, crown for the sacred.

Worth knowing: Assigning each chakra a rainbow colour is a modern Western convention, not a feature of the original texts.

Hindu and Buddhist tantric texts; the familiar seven-colour rainbow scheme is a 20th-century Western arrangement.

Looks like: Two equilateral triangles overlapped point-to-point, forming a six-pointed star with an open hexagon in the middle.

Jewish identity and protection — the 'shield' of David. The two triangles are often read as heaven reaching down and earth reaching up, meeting in the middle.

The hexagram is ancient and widespread; its use as the emblem of Jewish community is documented from medieval Prague and became universal in the modern era.

Looks like: A five-pointed star drawn as one unbroken line, often set inside a circle — then it is called a pentacle.

Four elements crowned by spirit, and the circle that holds them. In practice it is worn for protection far more often than anything else.

Worth knowing: Point-up it is the ordinary form used in Wicca and in medieval Christian art; the inverted form is the one later given a satanic reading.

Found on Mesopotamian tablets; adopted by the Pythagoreans, used in medieval Christian art, and central to modern Wicca.

Looks like: Two straight bars crossing, with the upright longer below the crossbar than above it.

Sacrifice and the promise that follows it. The single most recognisable religious mark in the world — and there are more than forty documented variants of it.

The central Christian symbol from late antiquity onward.

Looks like: Two curved lines crossing at the tail and meeting at a point, outlining a fish in a single gesture — no eye, no fins needed.

A password in a mark. The Greek word for fish spells the initials of a confession of faith, and it was drawn where saying it aloud was unsafe.

Early Christian, from roughly the 2nd century CE.

Looks like: A capital 'P' laid over an 'X', sometimes with an Α and an Ω hanging from the arms.

The first two letters of 'Christ' in Greek, folded into one monogram — faith compressed into a single stamp.

Adopted as an imperial standard under Constantine in the early 4th century CE.

Looks like: The Greek letters Α and Ω set side by side, or hung from the arms of a cross or Chi-Rho.

The first and last letters of the Greek alphabet standing for the beginning and the end — everything, with nothing outside it.

From the Book of Revelation; used in Christian art from late antiquity.

Looks like: A heart wrapped in a crown of thorns, crowned with flame and often pierced or bleeding, with rays behind it.

Love that has been wounded and keeps burning anyway — devotion that costs something.

The Catholic devotion spread from the visions of Margaret Mary Alacoque in the 1670s.

Looks like: A white bird in flight, wings spread, very often carrying an olive sprig in its beak.

The all-clear after the storm. Peace, the Holy Spirit, and news that the worst is behind you.

The olive-branch dove comes from the Genesis flood account; used in Christian art from the earliest period.

Looks like: A thin crescent moon opening to the right, cradling a single five-pointed star.

Read today as an emblem of Islamic identity and of the lunar calendar the faith keeps time by.

Worth knowing: It is a cultural and national emblem rather than a doctrinal requirement of Islam, and it predates the religion.

A pre-Islamic Near Eastern and Byzantine emblem later adopted by the Ottoman Empire and, through it, widely associated with Islam.

Looks like: A thin curved sliver of moon, thick at the middle and tapering to two points.

Beginnings and intuition. The waxing crescent is the moon on its way up — the traditional moment for starting rather than finishing.

A moon emblem appears in Mesopotamian, Egyptian, Greek and later traditions.

Looks like: A full circle in the middle with a waxing crescent on the left and a waning crescent on the right, backs turned outward.

Three phases of a life — maiden, mother, crone — and the idea that each one is a whole stage rather than a step toward the next.

Worth knowing: This is a 20th-century construction, not an ancient tradition.

Modern; the triple-goddess reading follows Robert Graves' The White Goddess (1948) and 20th-century Wicca.

Looks like: A disc with rays radiating from it, sometimes with a face drawn in the centre.

Life, clarity and visible power. Where the moon governs the inner world, the sun governs the one everyone can see.

Solar emblems are documented in nearly every ancient culture, from Egypt to Mesoamerica.

Looks like: Points radiating evenly from a centre — five points most often, six or eight in older and religious use.

Something fixed to steer by. Hope, destiny and guidance held out at a distance you can see but not reach.

Star emblems appear across ancient Mesopotamian, Egyptian, Greek and later heraldic use.

Looks like: A banded arc of colour across the sky, red on the outside, violet inside.

A promise kept after the storm — and, in several traditions, a bridge between the human world and whatever is above it.

Read as a divine sign in the Hebrew Bible, as the messenger Iris in Greek myth, and as the bridge Bifröst in Norse myth.

Looks like: A tapering tongue of flame, often shown rising from a bowl, lamp or altar.

What purifies and what consumes, at once. Passion, transformation, and the memory that is deliberately never let go out.

Sacred fire is attested in Zoroastrian, Vedic, Greek and Roman practice.

Looks like: A many-pointed star inside a circle, the north point marked with a fleur-de-lis or an arrowhead.

Knowing which way you are facing. Direction, purpose, and the pull toward getting home.

Drawn on portolan sea charts from the 14th century onward.

Looks like: Eight ornate staves radiating from one point, each ending in a different arrangement of bars, hooks and forks.

Its manuscript note says the bearer will not lose their way in bad weather, even on an unknown road — so it is worn as a charm for finding the way through.

Worth knowing: Despite the nickname, it is a 19th-century Icelandic magical stave, not a Viking Age symbol. No Viking-era example exists.

First recorded in the Huld manuscript, Iceland, 1860.

Looks like: A short-handled hammer with a broad rectangular head, worn head-down as a pendant.

The hammer that blessed and defended. Protection, strength and the sanctifying of a marriage, a birth or an oath.

Pendants are found in Viking Age graves and hoards, 9th–11th centuries CE.

Looks like: Angular characters built from straight strokes with no curves — shapes made for carving into wood, bone and stone.

An alphabet first, but each letter also carries a name and an idea, which is why runes are cast and read as a set of prompts.

Germanic; the Elder Futhark is attested from about the 2nd century CE.

Looks like: A vertical shank with a crossbar near the top and two curved flukes at the bottom — a cross with hooks.

Hope that holds. It was drawn where a cross was dangerous to draw, and it still means steadiness in rough water.

Carved in the Roman catacombs by early Christians; a maritime emblem ever since.

Looks like: A straight shaft with a pointed head at one end and flights at the other; sometimes two crossed, sometimes bundled.

Direction and intent. One arrow is a path forward; two crossed traditionally means alliance; a bundle means strength in numbers.

A weapon and an emblem across nearly every culture with a bow.

Looks like: A sideways figure-eight — one line crossing itself once and closing.

No beginning, no end. Worn for a bond meant to outlast circumstances, and for the idea that some things do not run out.

Worth knowing: It is a 17th-century mathematical notation, not an ancient mystical symbol, though it is now used as one.

Introduced as a mathematical sign by John Wallis in 1655.

Looks like: Two infinity loops layered or linked together, sometimes stacked, sometimes interlocked.

Two endless things rather than one — most often read as endless love and endless friendship, or two lives that keep running together.

A modern jewellery and tattoo motif built from the mathematical sign.

Looks like: Two rounded lobes meeting at a point below — nothing like an anatomical heart.

Love, and specifically love as something felt rather than reasoned. The oldest use of it in Europe is romantic, not religious.

The familiar two-lobed shape emerges in European art in the 13th–15th centuries.

Looks like: Two hearts overlapping, linked, or one nested inside the other.

Love that goes both ways. Two people, or a love shared between them rather than aimed from one at the other.

A modern jewellery, emoji and tattoo motif.

Looks like: A shaft with a looped or ornate bow at one end and a toothed bit at the other.

Access. What is locked can be opened — opportunity, a secret entrusted, and the threshold of a new chapter.

An attribute of Janus and Hecate in Greco-Roman religion, and of Saint Peter in Christian art.

Looks like: Two glass bulbs joined at a narrow waist in a frame, sand falling from the top to the bottom; sometimes with wings.

Time running, and the fact that it only runs one way. Winged, it says the same thing louder — time flies.

In use in Europe from the 14th century; a standard memento mori motif on early modern gravestones.

Looks like: A human skull, front on — plain and stark in European use, painted with flowers and colour in the Mexican form.

Remember you will die — which in both traditions is an argument for living, not a threat. The Mexican calavera is celebratory rather than grim.

A memento mori motif in European art from the late medieval period; the decorated calavera belongs to Mexican Día de los Muertos.

Looks like: A central beam with a pan hanging from each end, held level.

Weighed and found equal. Justice, fairness, and the reckoning that measures rather than punishes.

The Egyptian weighing of the heart appears in the Book of the Dead; the Greek and Roman goddesses of justice carry the same instrument.

Looks like: A straight double-edged blade with a crossguard — which is why an upright sword reads as a cross.

Courage, and the cut that separates truth from the rest. Point down it means peace; crossed, conflict.

A near-universal emblem in heraldry, religious art and myth.

Looks like: A flat plate wide at the top and tapering to a point at the bottom, often quartered or charged with devices.

Defence rather than attack — protection, identity and the family or cause you stand behind.

The heraldic shield is the base of European coats of arms from the 12th century onward.

Looks like: A circlet with raised points or arches, often jewelled, sometimes closed at the top with an orb and cross.

Authority granted rather than seized, and the responsibility that comes with it. Also victory — the winner's wreath became the ruler's crown.

Head ornaments marking rank are documented from the ancient Near East onward; the arched European crown develops in the medieval period.

Looks like: A U-shaped iron band with nail holes around the outer edge.

Luck caught and kept. Hung points-up in most of Britain so the luck cannot pour out, and points-down elsewhere so it pours over the door.

A European folk charm; the luck tradition is tied to iron and to the legend of Saint Dunstan.

Looks like: A slender Y-shaped bone from a bird's breast, two arms joined at a curve.

A wish that has to be won. The one left holding the longer half gets it — which is where 'a lucky break' comes from.

The custom is traced to the Etruscans, passed to Rome, and carried into English and American practice.

Looks like: A willow hoop with a loose web woven across it, a hole at the centre, and feathers and beads hanging below.

In Ojibwe tradition it is hung over a child's cradleboard, and the web is said to catch what should not reach the sleeper.

Worth knowing: This is a specific Ojibwe tradition, not a general 'Native American' one; hundreds of distinct nations hold hundreds of distinct beliefs.

Ojibwe (Anishinaabe) in origin; adopted widely across other Native nations during the Pan-Indian movement of the 1960s–70s.

Looks like: A single quill with barbs fanning from a central shaft, usually shown falling or drifting.

Lightness, and a message from somewhere higher. In Egypt a heart lighter than a feather passed the test; today a found white feather is widely read as a sign of comfort.

The feather of truth belongs to Egyptian funerary religion; feathers carry meaning in many separate traditions.

Looks like: A pair of feathered wings spread symmetrically, often flanking a central object or initial.

Rising above the situation — freedom, protection from above, and the memory of someone who is no longer here.

Winged figures appear in Mesopotamian, Egyptian, Greek and Christian art.

Looks like: A long-tailed bird with wings spread, rising out of flames.

What burns down and comes back. The standing symbol for surviving a collapse and being remade by it rather than despite it.

Described by Herodotus in the 5th century BCE, drawing on the Egyptian bennu bird.

Looks like: A horse in profile with a pair of feathered wings rising from its shoulders.

Inspiration that lifts you off the ground. Where his hoof struck, the spring of the Muses opened — so he stands for imagination as much as freedom.

Greek myth; the winged horse born from Medusa's blood, tamed by Bellerophon.

Looks like: A straight staff with a pair of wings at the top and TWO snakes twined around it, facing each other.

The herald's badge — safe passage, negotiation, trade and messages carried between worlds.

Worth knowing: It is not the medical symbol, despite being used as one in the United States. Medicine's emblem is the Rod of Asclepius: one snake, no wings.

The herald's staff of Hermes/Mercury in Greek and Roman religion.

Looks like: A plain rough staff with ONE snake coiled around it — no wings, no second snake.

Healing, and the renewal a shedding snake stands for. This is the genuine emblem of medicine.

Greek; the attribute of Asclepius, god of healing.

Looks like: A snake or dragon curved into a ring, its jaws closed on its own tail.

The cycle that feeds itself — ending and beginning as the same point. Alchemists used it for matter that is destroyed and reformed without loss.

Earliest known example in the Enigmatic Book of the Netherworld in Tutankhamun's tomb, 14th century BCE; later central to Greek alchemy.

Looks like: A long body coiled, curled into an S, or wrapped around a staff, tree or arm.

Renewal, because it sheds its skin and keeps living — and danger, because it also bites. Almost no culture reads it as only one of the two.

A charged symbol in Mesopotamian, Egyptian, Greek, Hindu and biblical tradition alike.

Looks like: Four broad patterned wings on a slim body, shown open and symmetrical.

Transformation that goes all the way — the same creature, unrecognisable. Also the soul, and a visit from someone who has gone.

The Greek word psyche means both 'butterfly' and 'soul'; the motif recurs across many traditions.

Looks like: A long thin body with two pairs of narrow transparent wings held out flat.

Change that arrives quickly, and light seen from a new angle — a creature that lives most of its life underwater before it ever flies.

An emblem of victory and courage in Japan, where it was worn on samurai armour.

Looks like: A round-headed bird facing forward, with two large front-set eyes.

Seeing in the dark. Wisdom, and specifically the kind that comes from watching quietly rather than speaking first.

The companion of Athena, stamped on Athenian coins from the 5th century BCE.

Looks like: A maned big cat, in heraldry usually rearing on its hind legs with claws raised.

Courage worn openly. Rule, nerve, and the willingness to be seen defending something.

A royal emblem from Mesopotamia and Egypt onward; the most common beast in European heraldry.

Looks like: A large hook-beaked bird with wings spread wide, head turned to one side; sometimes with two heads.

Height and vision — seeing the whole field before acting. Authority that is meant to look far ahead.

The bird of Zeus and the standard of the Roman legions; later the emblem of many empires and states.

Looks like: A long-muzzled canine in profile or head-on, often howling.

Loyalty to the pack and instinct trusted over instruction. It carries both readings at once — devoted family, and something you do not corner.

Central in Norse myth (Fenrir, Geri and Freki) and in Roman foundation legend (the she-wolf of Romulus and Remus).

Looks like: In East Asia, a long serpentine body with legs, whiskers and no wings. In Europe, a scaled beast with bat wings and a spiked tail.

Two nearly opposite readings. The Chinese dragon brings rain, luck and imperial authority; the European dragon guards a hoard and has to be fought.

The Chinese long is documented from the Neolithic onward; the European winged dragon develops through medieval literature.

Looks like: An elephant in profile, very often with the trunk curled upward.

Obstacles cleared, and memory that does not let go. The raised trunk is the part read as good fortune.

Ganesha, the elephant-headed remover of obstacles, is among the most widely worshipped Hindu deities.

Looks like: A tight spiral of layered petals on a thorned stem.

Love with a cost attached — the thorn is part of the symbol. A rose hung over a table in Rome meant everything said beneath it stayed there, which is where 'sub rosa' comes from.

Sacred to Venus in Rome, and the central flower of European love symbolism from the medieval period.

Looks like: Three stylised petals — one upright, two curving outward — bound by a horizontal band near the base.

Purity and royal descent, read in Christian art as a lily of the Virgin. Now as much a decorative mark as a political one.

The emblem of the French monarchy from the 12th century; ubiquitous in European heraldry.

Looks like: A slim branch with narrow pointed leaves, sometimes with small fruit.

The offer to stop fighting. Extended by hand it is a request; carried by a bird it is the news that the flood is over.

A Greek and Roman emblem of peace and victory; also the sign carried by the dove in Genesis.

Looks like: Three rounded leaflets on one short stem — three, not four.

Three held as one, and Irish identity. Distinct from the four-leaf clover, which is about rarity rather than doctrine.

The emblem of Ireland; the tradition that Saint Patrick used it to explain the Trinity is recorded from the 18th century.

Looks like: Four rounded leaflets on one stem, usually one slightly smaller than the rest.

Luck you found rather than luck you were given. The four leaves are traditionally read as faith, hope, love and luck.

A European folk luck charm; the luck comes from the genuine rarity of the mutation.

Looks like: A single nut sitting in a scaled cup, often paired with a lobed oak leaf.

Everything large starting small, and the patience that requires. Strength that grew slowly and will outlast you.

The oak is sacred in Norse, Celtic, Greek and Roman religion — the tree of Thor, Zeus and Jupiter.

Looks like: A jointed hollow stem with narrow leaves fanning from the nodes.

Bending without breaking. Hollow inside, which is read as an open mind, and upright outside, which is read as integrity.

One of the 'Four Gentlemen' of Chinese art, alongside plum, orchid and chrysanthemum.

Looks like: A single open eye inside a triangle, with rays of light radiating outward.

Being watched over rather than watched — in its original Christian use, divine providence attending to human affairs.

Worth knowing: It entered use as Christian religious art long before any secret-society association was attached to it.

Christian and Renaissance European art from the 16th–17th centuries; placed on the Great Seal of the United States in 1782.

Looks like: Plain triangles: fire points up, water points down, air points up with a bar through it, earth points down with a bar.

The four classical elements, and by extension four temperaments — drive, feeling, thought and steadiness.

European alchemy, systematised in the medieval and early modern periods from the Greek four-element theory.

Looks like: Nineteen equal circles overlapping in a hexagonal grid, making a rosette of pointed petals inside one outer ring.

A pattern read as the blueprint everything is built from — order underneath apparent randomness.

Worth knowing: The motif is genuinely ancient; the name and the meanings attached to it are modern.

The overlapping-circle rosette is ancient and widespread — examples are incised at the Osirion at Abydos in Egypt — but the name 'Flower of Life' and its sacred-geometry reading are late 20th century.

Looks like: A circle containing a vertical line with two lines dropping diagonally from its centre.

Peace, and originally nuclear disarmament specifically. The lines are the semaphore signals for N and D.

Designed by Gerald Holtom in 1958 for the British Campaign for Nuclear Disarmament.

Looks like: Two upright posts carrying two horizontal beams, the top one curving up at both ends — usually vermilion.

A threshold. Nothing is enclosed and nothing is locked; passing through it is the act of leaving the ordinary behind.

The gate marking the entrance to a Japanese Shinto shrine.

Looks like: A single circle brushed in one stroke of ink, usually left slightly open, with the brush marks showing.

Wholeness that does not need to be tidy. It is painted once and never corrected, so the gap and the wobble are the point.

A Japanese Zen brush practice.
