Like many languages, there are two genders in Gaelic, as a general rule, the article for “a” like “a sheep” does not exist, therefore you will not see it in Gaelic. There are articles for “the” (a and am) but since “an” can have many meanings, such as common articles, possessive, preposition, question, etc it cannot be used to define gender, these articles also change depending on the first letter of the following word, my advice is to learn the gender and its accompanying article and keep in mind that before B, F, M or P it will always be M.
The verb “to be”
Tha mi : (ha mee) I am
Tha thu: (ha oo) You are
Tha e: (ha eh) (as in get) He is
Tha i: (ha e) (as in feet) She is
Tha sinn: (ha sheen) We are
Tha sibh: (ha shiv) You (Pl) are
Tha iad (ha eeut) They are
