Usage notes

In modern usage, this preposition has inflected forms only in the plural. Idir is used with nouns and with singular pronouns in combination with another noun or pronoun:

idir é agus mé‎ ― between him and me

In the meaning ‘between’, this preposition does not trigger any initial mutation. In the meaning ‘both (... and ...)’ it triggers lenition of both the word following it and the word following agus.
