"The boy eats an apple."
Translation:Itheann an buachaill úll.
I'm not really sure what you are asking, but the basic order of a sentence in Irish is "Verb-Subject-Object" so itheann an buachaill úll.

But Irish doesn't have a verb for "have", so to say "X has Y" you use the construction tá Y ag X.

I am Irish, I grew up learning both Connemara and Donegal Irish, I got a wrong answer for 'Itheann an buachaill an úll' , as a native speaker this is what I would say. I use duolingo to brush up on my language because if you don't use it enough you forget it. Sometimes this app gets it wrong and some comments don't help. I understand Munster Irish can be different so this might explain it?
Why wouldn't it be correct?
Masculine nouns that start with a vowel get a t-prefix after the singular definite article in the nominative case:
an t-aerfort, an t-eireaball, an t-iasc, an t-ollamh, an t-uachtarán
Feminine nouns that start with a vowel don't:
an abhainn, an eilifint, an íomhá, an ollscoil, an ubh
It's not very fun for us Americans that are used to English as our first language, but you'll find that we put words in a very different order than other languages. I took 3 years of spanish in college and you see this kind of thing often. It's just the way Irish developed as a predecessor to English.
"I" in Irish is mé. It doesn't have anything to do with the verb to be. There are two different forms of "to be" in Irish, which as used in this question are Tá and Is. They refer to two different types of being. Is ... mé refers to WHAT something is, while Tá mé ... refers to HOW somthing is. For example. "Is buchaill mé" means that you are a boy, while Tá mé (usually shortened to Táim) means how you are it. For example: Táim tart.
The Irish course on Duolingo was set up with the expectation that people who already speak Irish would take the course, and, at some point one of those people suggested that as a correct answer. There are indeed narrow circumstances in which it could be used to translate this exercise.
When you submit a wrong answer, Duolingo doesn't just give you the sentence that the course creators want to teach, it check to see if your answer was close to any of the alternative answers, and presents that as the "right" answer, even though that's sometimes more confusing for learners.
So, the word order is eats, the boy, apple? Verb, subject, object? What's up with Irish's strange word order?
