What is a perfixes of behave?

A prefix is a group of letters added to the beginning of a Word to modify its meaning. The Word "behave" itself does not have commonly used prefixes, but if we consider "un-" as a prefix, it would form "unbehave," which is not standard English. Instead, "misbehave" is a more appropriate example, where "mis-" serves as a prefix meaning to act incorrectly or poorly.
