Caesura is a noun that refers to an interruption or break. 

The Latin word caedere (ky DARE ay) means ‘to cut.’ Since the mid-16th century, our word of the day has been used by English speakers to refer to something that cuts someone off. Example:

After about an hour of a really tedious meeting, we were mercifully given a caesura. This much-needed break was a helpful way to let us rest up and prepare for three more boring hours.
