To grace or adorn something; to add beauty, elegance, or blessing to something.
From be- + grace (from Old French grace, from Latin gratia meaning 'favor' or 'charm'). The verb form with be- means to confer grace upon or to embellish.
The word 'grace' comes from the Latin concept of divine favor, but by adding be-, English speakers could turn it into a verb meaning 'to make graceful'—it's a perfect example of how English's flexible word-formation system lets us treat abstract qualities as things we can give to others.
