Not to have the same traits or characteristics; to be unalike or distinct.

In plain English: To differ means to be different from something else.
"The two brothers look alike but they differ in their personalities."
Usage: Use "differ" to indicate that two things are not alike in specific ways or possess distinct characteristics. It describes a state of being unalike rather than an active process of changing.
The word "differ" comes from the Latin verb differō, which originally meant to carry apart or put off. It is formed by combining the prefix dis-, meaning "apart," with ferō, meaning "to carry."
