What does rev mean?
Rev is a short, informal word with two strongly recognizable uses. In political and social contexts, it means a revolution or uprising, as in describing a campaign of resistance as a rev against authority. It can also refer to one complete rotation of an engine or another rotating mechanism; the plural revs is particularly common when describing engine speed, as in “running at high revs.” As a verb, rev means to speed up an engine and, figuratively, to increase enthusiasm, activity, or intensity. The word is especially associated with informal and rebellious registers in its political sense, but its mechanical use is widespread in ordinary and technical English. Its brevity makes it useful in headlines and conversation, although revolution or a more precise term may be preferable in formal writing. Rev ultimately comes from revolution and belongs to a family of English words connected with the idea of turning, cycling, or profound change.

Rev compresses both a political upheaval and an engine at full throttle into four letters.
