not all
Less than everything
Not all limits a statement to some members of a group rather than every member: Not all birds can fly, Not all criticism is constructive.
The phrase often corrects overgeneralizations or introduces exceptions.
In logic, "not all X are Y" means at least one X is not Y—distinct from "no X are Y."
