“Humor sentence” or “sentence with a humor”

Why “Humor sentence” is incorrect

The phrase “humor sentence” is not standard English because:

1. Word order — In English, the adjective comes before the noun, but humor is a noun, not an adjective. The correct adjective form is humorous.
2. Correct way — You say “humorous sentence” (a sentence that is funny).

“Sentence with humor” — This phrase is grammatically correct because humor is a noun acting as the object of the preposition with. But it still needs no “a”: say “sentence with humor” not “sentence with a humor” because humor is uncountable.
