"Fluctuation" flowed into English from "fluctus," the Latin noun meaning "wave." "Fluctus" came from the Latin verb "fluere," which means "to flow." Which of the words below do you think also comes from "fluere"?

"Affluence" comes from the Latin "affluere," which means "to flow abundantly," and which ultimately comes from "fluere." "Affluence" refers to a tide of material wealth which has "flowed abundantly" to someone. It can also have a more literal meaning, such as the "affluence," or flow, of a stream. The adjective "fluent," which points to the ability to flow, change, or move smoothly is another "fluere" descendant. It frequently describes someone from whom words "flow" easily. The noun "influence" also comes from "fluere." It originally referred to a fluid believed to flow from the stars that caused people to act a certain way.
