So I'm guessing that this is an exception the rules?
Yes, unfortunately a lot of words are exceptions
Why is "birds" plural masculine but "speaking" is plural feminine?
Jarrettph is right. "ציפורים" is actually feminine, even though it has
the "ים" ending which makes it appear to be masculine.
So how would I write it if I wanted to say that only male birds are speaking?
I'm not sure if you can but if you could, you'd presumably use the masculine plural מדברים.
Even though ציפור is a feminine word that doesn't mean that whenever you use it that it is referring to a female bird. So, if I say ציפורים that wouldn't necessarily mean that I was saying female birds, just that I am talking about birds in general.
I'm guessing tsiporim is an irregular noun.
How is מדברות pronounced?
Same difference. The forvo link is a native speaker I'm pretty sure. The ə sound can be interpreted as a or e.
Should get a spelling correction rather than error
So when and how do we know there are exceptions?
