To make someone laugh or smile, or to provide entertainment or enjoyment to keep someone's mind occupied.
From Old French 'amuser' (to cause to muse or wonder), from 'a-' (to) + 'muse' (to think). Originally meant to distract or bewilder, then evolved to mean entertain pleasantly.
The word 'muse' is connected to the Greek Muses (goddesses of inspiration), so 'amuse' literally means 'to turn away from thinking'—it's why a joke or funny video amuses you, because laughter is basically your brain getting delightfully distracted!
