Possessive Pronouns

for a definition see Possessive Pronoun (definition)

There are two ways to indicate possessive pronouns (my, your, his, her, our, their) in Gaelic. The first way, which is both more formal and indicates a close relationship between the possessor and the possessed item, uses a pronoun that comes before the noun. The second way, which can be used for a less close relationship (and is, in fact far more common) is to combine the use of a noun and an article followed by an inflected form of the preposition aig

Prenominal possessive pronouns

Gaelic has pronouns roughly equivalent to English my, your, his, her, etc. However these tend to only be used when the possession is of a particularly close or personal nature. For example, they are used with body parts (my arm), family members (my mother), and possession that is clearly ownership and not temporary.

Person	Singular		Plural
1	my	mo^L	our	àr^N
2	your	do^L	your	ùr^N
3 masc	his	a^L	their	an/am
3 feminine	her	a^H	their	an/am

Notes:

^L stands for lenition trigger, ^N stands for Eclipsis/nasalization trigger, ^H indicates the word prefixes an <h> in front of the following word. These letters are not written but are provided here as guides.
am is used instead of an in front of words beginning with any labial consonant (i.e. <b, m, f, p>), eg. their table am bòrd
before words beginning with vowels "mo" is reduced to mo', do is reduced to d', and a^L his is deleted.
