this has too many diffrent meanings: she is sarah, she sings\is singing, she is a minister
"Sings" is pronounced as "shara", while "Sarah" and "minister" are pronounced as "sarah". The place of the stress can help to differentiate between these two meanings - if the stress falls on the last syllable it means "minister", on the first it means "sarah".
To clear up any possible confusion, you mean "minister" as in the noun "minister", right, and not the verb?
Does this only mean minister as in a government minister "שר הביטחון" or can it also be a minister of a church?
So, as an example sentence (He is my minister), I could have:
הוא השרה שלי.
Is this correct?
This is a chapter dealing with verbs, so it would only make sense that it would be a verb, namely the verb for to sing
True, but you can strengthen the entire tree at once if you just click strengthen on the main page, so it's possible to get a word or a sentence taken out of the context of its specific skill group.
