"'S e hama a th' ann."
Translation:It is ham.
Basically every time you see an apostrophe in Gaelic, the apostrophe is representing a letter.
In this case the apostrophe in 'S is representing the letter i. So 'S is "is", as in the phrase "is mise". The apostrophe in th' is representing the letter "a". So "th'" is "tha".
The reason both "is" and "tha" are used is because you are using "is" to identify the object as ham, and then using "tha" to reinforce that identification by describing it as being in its state of being as ham. Basically, it's definitely ham.
Oh I see! I didn't know that! Thanks so much! I found out in another sentence that " 'S e" means "It is" and "A th' ann" means "That it is", but this definitely helps with explaining it! What does the "a" mean in "A th' ann" mean though? I know th'/tha means is, and "ann" means "there", but not sure about "a"? Maybe someone explained it already, but I've forgotten :/
