rhombo-comb. form

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

Forms: 1800s– rhomb-, 1800s– rhombo-.

Origin: Of multiple origins. Partly a borrowing from Latin. Partly a borrowing from Greek. Etymons: Latin rhombo-; Greek ῥομβο-.

Etymology: < post-classical Latin and scientific Latin rhombo- and its etymon medieval Greek ῥομβο-, combining form (in e.g. ῥομβοτετράγωνος having the shape of a rhombus) of ancient Greek ῥόμβος rhombus n. Compare -o- connective.Borrowings and adaptations of Latin words (in some cases via French) are found from the early 16th cent. (e.g. rhombus n., rhomboid n.). Formations within English are found from the early 19th cent. onwards. Compare French rhombo- (formations in which are found from the late 18th cent.: see rhomboèdre rhombohedron n.).
