phloro-comb. form

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

Forms: Before a vowel phlor-

Origin: Formed within English, by compounding. Etymons: phlorizin n., -o- connective.

Etymology: < phlor- (in phlorizin n.) + -o- connective.Formations are found from the first half of the 19th cent., chiefly after French or German models. Compare French phloro- (formations in which are found from the first half of the 19th cent.), German phloro- (formations in which are found from the 19th cent.).
