"There are clothes in the basket."
Translation:Tá éadaí sa chiseán.
I apologize. That must have been a stupid question to ask. Apparently someone somewhere mentioned that h- and t- were added to separate or perhaps it would be better said as clarifying pronunciation when vowels are next to each other in certain circumstances. Obviously I got that wrong, and I apologize for asking the question.
Unfortunately, people say a lot of simplistic and inaccurate things to learners (of any topic, not just languages). Some of them are just simplifications, because a learner doesn't know enough to understand a more complex explanation, and some are just "myths" that are so appealing simple that they persist, even after learners start seeing counter-examples, though in this case, most learners will have used sentences starting with Tá an before they are told this particular "myth".
There are certain limited circumstances where a words that starts with a vowel gets a h-prefix after specific words that end in a vowel. "separating the sounds" is sometimes the justification for doinf this. But these are actually the exceptions, not the rules - there are many, many more places where a word starting with a vowel quite happily follows a word ending in a vowel.
Hello, it seems I am the one who began this topic long ago. First of all, I would like to thank Katy for the interest shown and our mods as well. Secondly, I hope you understand I don't take any other source to learn the Irish language rather than Duolingo and teangalan, or other dictionaries I am currently using on my mobile phone. I apologise if my question sounded stupid, perhaps it was, and you are utterly right when telling there is not a specific need in Irish to separate vowels. I believe I saw some words on some of the exercises provided in the platform putting and "h" before some substantive beginning with a vowel. That made me think there was some kind of linguistic rule, that I repeat, I assumed it wrong from some exercises. For example A húll. Now I understand the "h" is used in the sentence to distinguish "her apple" from "his apple".
That is all my question was about. Thank you very much to all the people who have made it possible to learn this beautiful language in Duo! I wish some day I could visit Ireland and study it firsthand.
