Etymology

Origin of hilarity

1560–70; earlier hilaritie, from Latin hilaritās, equivalent to hilari(s) ( see hilarious) + -tās -ty 2

Explanation

Hilarity is that side-splitting, tear-inducing, laugh-until-you-can't-breathe happiness of a romping good time. There's usually an atmosphere of hilarity just after the ball drops on New Year's Eve. It's that feeling of cheerfulness — hilaritas in Latin — that fills the room when the clock strikes midnight. If your teacher passes out cupcakes and lets you play games instead of reading aloud, she may have a hard time controlling the ensuing hilarity in the classroom.
