The noun pause means "a short break," like the pauses in television shows that allow for commercials to be shown.
Pause can also be a verb that means "to stop for a short time." Teachers, for example, often pause after making an important point to check that students understand and to give them time to ask questions. Pause which rhymes with laws and cause, comes from the Greek word pausis, "stopping, ceasing," which comes from pauein "to stop, to cause to cease." Why don't you pause and think about that for a moment.
