Homophones

[starseeker]

Paw and paw are the same word.

Hair, hare, hear and here is the only four-way homophone that I know of.

Maw and ma are most certainly different.

It depends on accent. For me hair and hare are the same. So are hear and here. But hair (h-air) and here (hee-ya) aren't the same for me.
