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
