Historically, the Irish declined prepositions developed from the merger of the independent preposition and the possessive pronoun. There is also a set of undeclined prepositions.
Simple prepositions govern the dative case (with some exceptions), while derived prepositions govern the genitive.
Prepositions may trigger initial mutations on proceeding words.
In Modern Irish, simple prepositions nearly always govern the dative, aka prepositional, with a few exceptions governing the accusative. Derived prepositions govern the genitive. In the lists below, prepositional governance is assumed unless otherwise indicated.
The declined prepositions are:
The undeclined prepositions are:
One-word prepositions derived from substantives, all governing the genitive and all undeclined, include:
The preposition chung is ultimately derived from a verb, governs the genitive, and is declined using the personal forms of chuig.
All two-word prepositional phrases govern the genitive. Most are formed as combinations of a preposition plus a substantive, e.g., ar nós, i ndiaidh, tar éis etc.

.The third person forms of Old Irish simple prepositions are case dependent (accusative or prepositional). The singular masculine forms are irregular, but the singular feminine, and the plural forms are tractable:
3rd per | acc | prep |
---|---|---|
sgf | + e | + i |
pl | + u | + ib |
In modern Irish, only fara has + e in the 3rd sgf, although it is not derived from an Old Irish preposition, but rather from ferr (the comparative of maith). All others have standardised to + i.
In the 3rd pl, only de and do have + ibh. All others have standardised to + u. The 3rd pl of le (leo) derives directly from an Old Irish variant.
The simple prepositions may trigger initial mutations on proceeding words. The paradigm in Modern Irish is very similar to Old Irish (cf. Etymology below), with a few exceptions, notably:
Mutation type | Prepositions |
---|---|
No mutation∅ | ag, amhail, as, chuig, fara, gan, idir (“between”), seachas; |
AspirationH | go, le |
LenitionL | de, do, faoi, idir... agus... (“both... and...”), mar, ó, roimh, trí, um |
No mutation for generalised, lenition for specific∅L |
ar, thar |
Lenition for generalised, no mutation for specificL∅ |
gan |
EclipsisN | i |
In Old Irish, the article in triggers case-dependent mutations. In the singular, the accusative triggers eclipsis, while the prepositional triggers lenition.
As prepositional grammar evolved in Modern Irish, the dialects diverged. Ulster Irish favoured the prepositional lenition, while the others, the accusative eclipsis.
In summary, for prepositions governing the dative, with the singular article:
