"You have water."
Translation:Tá uisce agat.
No, tá is the present tense of the verb to be, uisce is the subject. Agat is the preposition ag merged with the pronoun tú.
There's no verb to have in Irish, you have to say things in a different way... Imagine you're talking like some wizard - "A great destiny is upon you!"="You have a great destiny".
Thanks for the explanation. I'm still a little confused about the "ta"? Is apple you have?
Is "Tá uisce agat." the same as "Tá uisce agat?" The first is a statement and the second is a question. Am I just not far enough in my learning to know the difference?
No. To ask a question, you have to put the interrogative particle an before the verb. Because tá is an irregular verb, the question form is an bhfuil.
An bhfuil uisce agat? - "do you have water?"
