英文词源


curve
curve: [15] Curve has a wide circle of relations in English. It comes from Latin curvus ‘curved’, which had connections with Greek kurtós ‘curved’, Greek korōnos ‘curved’ (source of English crown), and Greek kírkos ‘ring, circle’ (source of English circle). When English acquired it, it was still an adjective, and English did not convert it into a noun until the 17th century.
=> circle, crown, curb
curve (v.)
early 15c. (implied in curved), from Latin curvus "crooked, curved, bent," and curvare "to bend," both from PIE root *(s)ker- (2) "to turn, bend" (see ring (n.)).
curve (n.)
1690s, "curved line," from curve (v.). With reference to the female figure (usually plural, curves), from 1862; as a type of baseball pitch, from 1879.
