"Elephants eat apples."
Translation:Itheann eilifintí úlla.
I have to agree. Some words are just used over and over again but others hardly at all. I may never remember what "seal" is and "The crab has water" I am never going to get because it doesn't make much sense. Why can't "The dog has water" be a sentence. THAT one I would use!
??? Why would you add a h-prefix?
Do you put a h-prefix between the ending vowel in tá & the beginning vowel in an? Or between the ending vowel in tá sé & the beginning vowel ag rith?
There is no general rule that requires a h between any word that ends in a vowel and a following word that starts with a vowel. When a h-prefix is used, it is only used between two vowels (or vowel sounds, at least), but that doesn't mean that you always use a h-prefix between two vowels - as the verb tá is extremely common and so is the definite article an, and prepositions that start with vowels regularly come after the pronouns sé and sí, the h-prefix is the exception, not the rule.
