I think that Duo is a cannibal...
But, are irrational things referred to it with הם or הן ? Cause if not it is canibalism.
ANY noun that is in plural can be הם or הן. Just like "they" in English. Not sure why that is even an issue.
For what reason can't we just say "?הם טעימים" Do pronouns always need "האם" in questions?
Yes/no questions start with האם. But it is often dropped and in spoken language considered optional. הם טעימים? is perfectly fine in conversation.
