im-
Not, as prefix
Im- is a prefix with two distinct origins.
One means "not" or "opposite of," appearing before words starting with b, m, or p: impossible, immature, imbalance.
The other means "in" or "into": implant, immigrate, imbue.
Context usually makes clear which sense applies—negation or direction inward.
