To make something more lively, energetic, or interesting; to add excitement or liveliness to.
From 'en-' (to cause to be) plus 'liven' (from 'live'), which in turn comes from Old English 'libban.' The word emerged in the 16th-17th centuries as writers sought a vivid verb for adding energy and vitality to things.
Enliven is one of the most useful English verbs because it describes that magical quality of bringing energy to something dull—a good song can enliven a party, a funny joke can enliven a dull meeting, and knowing about the history of words can enliven your understanding of the English language.
