Ach
An interjection expressing mild annoyance, resignation, dismissal, or affectionate scepticism. 'Ach, away with you.' 'Ach, sure I don't mind.' The throat-clearing 'ch' marks the speaker's Northern register; the meaning is in the tone.
Etymology
From Irish 'ach' (= but) and Scots Gaelic 'ach' (also 'but'), reinforced by the parallel German 'ach' (= alas, oh). The voiceless velar fricative /x/ on the end is the Irish/Scottish inheritance; many speakers approximate it with /k/ ('ack') when the velar fricative is hard. The compound forms 'och' and 'ack' are sibling interjections, all in the same family.
In a sentence
"Ach, don't be worrying about it - it'll come right in the end."
Historical notes
Ach is one of the most-spoken Hiberno-English and Ulster Scots words and one of the hardest to pin down. It can mean disagreement ('ach, that's not right'), resignation ('ach, what can you do'), dismissal ('ach, away on'), or quiet emphasis ('ach, sure I know'). Tone carries all the meaning. The word's near-twin 'och' does the same work; 'ach' is more often spelled in Ulster Scots, 'och' in southern Hiberno-English, but speakers use both interchangeably.
Alternate spellings
och · ack
