Irish prepositions and prepositional pronouns

In Irish, a preposition and a pronoun fuse into one word: ag (at) + mé (me) = agam (at me). These fused words are called forainmneacha réamhfhoclacha, prepositional pronouns. They carry a lot of everyday Irish: tá leabhar agam (I have a book), is maith liom (I like), tá eagla orm (I am afraid).

Mutations

Most prepositions change the first letter of the next noun. Each preposition’s page shows exactly what happens: for example ar bhord (on a table) but ag doras (at a door).
