Old Irish object pronouns are affixes attached to the verb. There are both suffixed pronouns and prefixed pronouns, of which latter are usually called “infixed pronouns” since they are inserted between a preverb and the verb and can never be the first morpheme in the verbal complex.
The suffixed pronouns are suffixed to absolute forms of simple active verbs only. In all other cases the infixed pronouns are used. The following forms are used only after 3rd person singular verb forms:
|3 m. & n.||-i||-us|
Before the suffixed pronoun, the -(a)id ending of the present tense is reduced to -th- (or -t- after a coronal consonant other than r), and the -(a)is ending of the preterite is reduced to -s-. For example:
- beirid (“carries”) + -i (“it”) = beirthi (“carries it”)
- sásaid (“satisfies”) + -um (“me”) = sástum (“satisfies me”)
- léicis (“(s/he) let go”) + -us (“her, them”) = léicsius (“(s/he) let her/them go”)
In addition to the above, the 3rd person singular masculine/neuter suffixed pronoun -it can be found:
- after a 1st person singular future verb form (the ending -a disappears), e.g. promfa (“I will try”) + -it (“it”) = promfit (“I will try it”)
- after a 1st person plural verb form ending in -mi (the two i’s merge into one), e.g. guidmi (“we pray”) + -it (“it”) = guidmit (“we pray for it”)
- after a 3rd person plural verb form ending in -(a)it (which reduces to -t-) e.g. gonait (“they slay”) + -it (“him”) = gontit (“they slay him”)
Despite the name, the infixed pronouns are technically prefixes rather than infixes as they always precede the entire root. However, they follow both preverbal particles and other prefixes, including those prefixes that are lexically part of the verb, e.g. do·gníu (“I do”) with an “infixed pronoun” becomes da·gníu (“I do it”). If no other preverb or prefix is available, they are attached to the “dummy preverb” no-.
There are three classes of infixed pronoun: class A, class B, and class C. Classes B and C are identical except in the 3rd person singular masculine and neuter.
|Person||Class A||Class B||Class C|
|1 sing.||m-L||dom-L, dam-L|
|2 sing.||t-L||dot-L, dat-L, dut-L, dit-L|
|3 sing. m.||a-N||d-N||id-N, did-N, d-N|
|3 sing. f.||s-(N)||da-|
|3 sing. n.||a-L||d-L||id-L, did-L, d-L|
|1 pl.||n-||don-, dun-, dan-|
|2 pl.||b-||dob-, dub-, dab-|
|L means this form triggers lenition.
N means this form triggers nasalization (eclipsis)
(N) means this form triggers nasalization in some texts but not in others.
Class A infixed pronouns are used after prefixes that were originally vowel-final: ro-, no-, di-, to-, fo-, ar-, and imm-, as well as the negative particle ní. The prefixes ro-, no-, di-, to-, and fo- lose their vowel before 3rd sing. m./n. a-, while a- itself disappears after ní, leaving only its mutation effect. The prefixes ar- and imm- take an epenthetic vowel (usually -u- or -i-) before the class A infixed pronouns that start with a consonant.
Class B infixed pronouns are used after prefixes that were originally consonant-final: ad-, aith-, com-, ess-, etar-, for-, fris-, and in-. The prefixes ad-, aith-, ess-, and in- all merge with the following pronoun to become atom-, atot-, etc.; com- merges with the pronoun to become cotom-, cotot-, etc.; and fris- merges with the pronoun to become fritom-, fritot-, etc.
Class C infixed pronouns are used:
- after preposition plus relative pronoun, e.g. indid·epiur (“in which I say it”)
- in relative clauses when the nonrelative takes class A, e.g. dod·gníu (“which I do”) (cf. class A da·gníu (“I do it”))
- in indirect relative clauses, e.g. hóre nondob·molor-sa (“because I praise you”)
- after the interrogative particle in, e.g. in da·hierr? (“will you slay them?”)
In many of these contexts, the infixed pronoun undergoes nasalization, so that the initial d- appears as nd- or even n-.
