Is monk a noun or a proper noun?

Answer 1

The noun 'monk' is a noun, a common noun, a general word for a male member of a religious community; a word for any monk anywhere.

A proper noun is the name or title of a specific person, place, or thing; for example, The Merry Monk (restaurant) in Saratoga NY or "Monk" the TV series.

Answer 2

The lower-case word "monk" is a regular noun, because it is not the name of a particular person, place or thing.
