This is a list of English language words from the Irish language with links provided to pronunciation in all three primarily Irish dialects, spoken by native Irish speakers, provided by Foras na Gaeilge.

banshee (from Irish bainsídhe/beansídhe, meaning "woman of fairy" or "of a fairy mound"

Bean (ban) is the Modern Irish word for woman. Síd(h) (modern spelling sí) is Irish for 'mound' (see Sidhe). In traditional Irish mythology, a spirit usually taking the form of a woman who sings a caoineadh (lament) warning of impending death in an old Irish family.

bog (from "boc", meaning "soft" or "marshy" and -aigh to form bogach meaning "soft soil composed primarily of peat")

Used as the Anglicized "bog" as slang for a mire, but also to become stuck or impeded.

bogeyman (possibly from bogaigh + English man)

The word bogaigh is pronounced approximately as "boggy", and the bogeyman legend originates from humanoid-appearing logs and human "bog-bodies" found well-preserved in peat. These occasional discoveries gave rise to unsettling stories some suggest may have been used to encourage good behavior from otherwise misbehaving children.

boreen (from bóithrín, meaning "country lane")

A narrow, rural Irish road.

bother (possibly from bodhar, "deaf; bothered; confused"; or from bodhraigh, "to deafen; to annoy")

The earliest use appears in the writings of Irish authors Sheridan, Swift and Sterne.

brock (from old Irish brocc)

A badger.

brat (from Old Irish bratt meaning "cloak, mantle")

A cloak covering or cloth. Also as swadding-clothes and bird's plumage.

brogan (from bróg, meaning "shoe" or "boot".)

A boot or shoe of untanned leather, often with holes in the sides or over the toes intended for drying while worn in wet conditions.

brogue (from barróg, meaning "to wrestle or grasp" with teanga (tongue) to mean an impediment of speech.)

Though found in wide use in English to indicate a heavy accent, the Irish do not use this term for the negative connotations.

clabber, clauber

(from clábar) wet clay or mud; curdled milk.

clock

O.Ir. clocc meaning "bell"; into Old High German as glocka, klocka (whence Modern German Glocke) and back into English via Flemish; cf also Welsh cloch but the giving language is Old Irish via the hand-bells used by early Irish missionaries.

colleen

(from cailín meaning "young woman") a girl (usually referring to an Irish girl) (OED).

corrie

a cirque or mountain lake, of glacial origin. (OED) Irish or Scots Gaelic coire 'Cauldron, hollow'

craic

fun, used in Ireland for fun/enjoyment. The word is actually English in origin; it entered into Irish from the English "crack" via Ulster Scots. The Gaelicised spelling craic was then reborrowed into English. The craic spelling, although preferred by many Irish people, has garnered some criticism as a faux-Irish word.

cross

The ultimate source of this word is Latin crux, the Roman gibbet which became a symbol of Christianity. Some sources say the English wordform comes from Old Irish cros. Other sources say the English comes from Old French crois and others say it comes from Old Norse kross.

drum (ridge), drumlin

(from drom/druim meaning "ridge") a ridge often separating two long narrow valleys; a long narrow ridge of drift or diluvial formation. Drumlin is a linguistic diminutive of drum, and it means a small rounded hill of glacial formation, often seen in series (OED). A landscape of many Drumlins occurs in some parts of Ireland (including counties Cavan and Armagh). Drumlin is an established technical word in geology, but drum is almost never used.

drisheen

dulse

esker

kibosh, kybosh

to finish, to put an end to: "That's put the kibosh on it". The OED says the origin is obscure and possibly Yiddish. Other sources suggest that it may be from the Irish an chaip bháis meaning "the cap of death" (a reference to the "black cap" worn by a judge passing sentence of capital punishment, or perhaps to the gruesome method of execution called pitchcapping); or else somehow connected with "bosh", from Turkish "boş" (empty). (Caip bháis - pronounced as kibosh - is also a word in Irish for a candle-snuffer.)

Leprechaun

(from leipreachán, based on Old Irish luchorpán, from lu 'small' + corp 'body' (ODE).
