curvi-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: A borrowing from Latin. Etymon: Latin curvi-.

Etymology: < scientific Latin and post-classical Latin curvi-, combining form of classical Latin curvus curve adj.; compare -i- connective. Compare French curvi- (formations in which are found from at least the early 19th cent.).Found earliest in the 17th cent. in curvilineal n., curvilinear adj., and related words. Found subsequently from the early 19th cent., in a number of borrowings and adaptations from Latin and French, and in new formations within English. Combining with second elements ultimately of Latin origin.
