Part of speech: verb, noun

Definitions

1. A tendency for a line or shape to rise or bend upward, reflecting an increase in measurement or value over a certain interval

Etymology: "Upcurve" is a plain compound: the prefix "up-" joined to "curve," so the word describes a line that bends or rises upward. The prefix "up-" is an old English element, used in English from its earliest records to mean motion or position toward a higher point, and "curve" comes from Latin "curvus," meaning bent or crooked, which entered English through French. The combination is transparent, so the word's meaning follows directly from its parts. It works as both a verb ("the road upcurves toward the ridge") and a noun ("the upcurve of the wing"), with the sense of a gentle rise rather than a sharp climb.

Synonyms: rise, ascend, increase, surge, climb
