Is there any general agreement among linguists about the meaning
of the terms homonym, homophone and homograph.

My dictionary lists 'homograph' as two words spelled the same but
with different pronunciation.  However, it seems to me that the latter
requirement is not necessary.  I would say that homoghraphs are spelled
the same and means something different, and may or may not be pronounced
the same.

Similarly and vice versa, mutatis mutandis, for homophone.

Then for homonym, my dictionary says both words must be of the same
word class (part of speech) but differ significantly in meaning. Again,
the first requirement does not seem essential to me.

What do other linguists think?
