A morphemic noun, person, place, thing, or idea, is a noun that can have suffix added to make it into an adverb word, which is a word used to describe a verb. In the case of the word "Man," you can use "Man" as a noun, for example "The man sat down." If you add "-ly" to the end, you get "manly", an adverb. "The boy had sang manly."
