Whats the difference between these two words? Please supply example sentences to cover the basic meaning of a versus á.

Thanks!

In Munster Irish:

A:

a is his/her/their, the third person possessive pronoun.

Tá a charr deisithe His car is fixed.

a is also the relative particle which/who:

Is é an sagart is túisce a dhein an obair It's the priest who first did the work.

a is often used with the verbal noun, to make what would be an infinite in English:

Ba mhaith liom an cloch san a thógadh I would like to life that stone.

a is used before numbers when counting:

a haon, a dó, a trí one, two three

It's also used in the vocative, that is when calling somebody's name:

A Bhreandáin

Á

á expresses at his/at her/at their.

Either in the form ag á, used in most situations:

Tá t'Athair ag á carr Your father is at her car.

Or just á on its own with verbal nouns, that is, to express what would be the object of a present participle
in English:

Táid siad á bhualadh They are hitting him.

never heard about it. You don't say "aigena carr" in Munster?
