“Trí” in Irish: frequently asked questions

What does trí mean in Irish?

trí means through. With a pronoun it becomes one word: tríom (through me), tríot (through you), tríd (through him / it).

What is the Irish for through me?

tríom. The preposition trí and the pronoun mé fuse into one word; this is a prepositional pronoun (forainm réamhfhoclach).

Does trí change the next word?

Trí lenites the next word (séimhiú): the first letter takes an h, trí fhuinneog. Tríd is the form before the article: tríd an doras (through the door).

Why do I sometimes see 'tríd' instead of 'trí'?

Before the article 'an' you use 'tríd', so you say 'tríd an doras' (through the door) and 'tríd an bhfuinneog' (through the window). On its own, 'tríd' also means 'through him' or 'through it'.

Is the preposition 'trí' the same as the number 'trí' (three)?

No, they are different words that look the same, and both lenite the next word, so 'trí fhuinneog' can mean 'through a window' or 'three windows'. The context tells you which one is meant.
