Think of a prop as a rotating, somewhat twisted, wing. Just like a
regular wing, the angle of the prop blade can cause the prop to stall,
i.e. experience a dramatic loss of lift. When this happens you end up
with very little lift, with the prop energy being used to turn the
prop against drag.
Usually the entire prop doesn't stall, but only a portion of it. You
can modify the twist of the prop to minimize the prop tips from stalling.
Okay, now that I've said something, someone will correct me so we will
have the "real" definition.
