Question

What do we call a group of words that has a subject and a predicate but does not make complete sense?

Answer 1

A clause, or even just a fragment.
it is not a full sentence.
hope that this helps. =)

Answer 2

Inproper i think because if its a subject is part of the predicate but the predicate it explains the subject but if they both don't make complete sense then i would say in proper unless I'm saying it wrong because I'm helping my little sis with her math home work but I am sorry if i gave u the wrong answer.
