"We are and they are."
Translation:Táimid agus tá siad.
This is somewhat confusing. I don't think the lesson covered "muid" at any point. But apparently Taimid is just the contracted form of Ta muid?
This is the first time I've seen muid as well. In workouts or lessons (I'm coming from a workout).
Not necessarily an alternate spelling, but an alternate form. Not all dialects contract the verbs in the first person singular and plural tenses. Munster does (actually, they contract in more tenses than that), but Connacht and Donnegal Irish don't.
On any smart or android phone just keep finger pressed down on a letter and it will display a menu of accents and you'll see the letter with the fada normally third or second from right.
If you have a touchscreen phone, usually, you just long press the letter and the letters with fadas are available.
