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.
Preposition lists and case governance
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:[rfi 1]
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.
|Number||Person||Suffix||Notes / Exceptions|
|Singular||1st||broad + m||slender: ó/ua (uaim)|
|2nd||broad + t||slender: do (duit), ó/ua (uait)|
|3rd m||various slender forms:
||broad: as, do (dó), i (ann)|
|3rd f||unvoiced + thi||

- The preposition ionsar = i + ar is declined as ar.
- Three prepositions ending in vowels (le, fara, trí (sg only)) use the 3rd sgm form before the article, e.g. leis an....
- Prepositions ending in vowels (de, do, faoi, fara, i, le, ó, trí) undergo contractions with other parts of speech, in particular the article. These forms are summarised in the Wiktionary template
- Some contractions with the article, especially those of i, retain the s of Proto-Celtic *sindos:
- i + an → insan > sa(n)
- i + na → insna > sna
- dialectic variants:
- de + na → desna
- do + na → dosna.
Third person suffixes
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:
|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:
- the "mixed mutation" prepositions: idir, ar, thar, gan
- those derived with significant changes: as, chuig, roimh
|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
|Lenition for generalised,
no mutation for specificL∅
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:
- Ulster Irish: lenition
- Other dialects: eclipsis, except:
- lenition is subject to the dntls rule
- lenition tends to trigger t-prothesis on s, especially for feminine nouns, e.g., sa tsráid
- eclipsis tends not to occur on d/t, e.g., ag an doras

- ^ Also referred to as common, or even nominative (as here on Wiktionary).
- ^ Except go dtí, which is a re-purposed subjunctive
- ^ In this phrase, tar is the Old Irish preposition, Modern thar, see C. Marstrander, E. G. Quin et al., editors (1913–76), “éis”, in Dictionary of the Irish Language: Based Mainly on Old and Middle Irish Materials, Dublin: Royal Irish Academy, ISBN 9780901714299
- ^ The underlying root of de is di (see etymology below), hence díom etc.
- ^ The underlying root of faoi is fo, fu (see etymology below), hence fúm etc.
- ^ Retains the n when declined, broadened as ion-.
- ^ idir has no singular synthetic forms in the standard.
- ^ Both forms exist in Old Irish. In Modern Irish, the independent preposition and its contractions are based on ó, while the declension uses ua-
- ^ Orthographic change, a→o.
- ^ That is, tríd an..., but trí na
- ^ Ar aghaidh leo ansin tríd an gcoill go mall
- ^ San before a vowel and lenited f. The form sa obeys the dntls rule, even though the n is missing, e.g. sa bhosca, but sa tsráid, sa tigh. In these forms, the original preposition i has disappeared.
- ^ Stifter, Lesson 18.1
- ^ There is only a couple of exceptions to the paradigm shown.
- ^ Also called h-prothesis.
- ^ Eclipsis in certain phrases, e.g. ar ndóigh
- ^ Lenition of b/p, g/c, m only, i.e., not d/t, f, s, i.e., dntls + f.
- ^ As well as Scots Gaelic
- ^ Entries for Middle Irish are given only if they differ significantly from Old Irish.
- ^ Supscripts /∅, L, H, N/ indicate the mutation triggered; /a, g, p/ indicate the case/s governed.
- ^ 3rd sg m of co.
- ^ 3rd sgf of do
- ^ From attested Primitive Irish ᚐᚃᚔ (avi)
- ^ From the PIE zero grade form *tr̥h₂-
- ^ Also gives the suffix -amhail > -úil.
- ^ Proposed etymology. See also um above.
- ^ Also as older, literary preposition seach.
