nitro-comb. form

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

Forms: before a vowel usually nitr-.

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

Etymology: < nitre n. + -o- connective. Compare Byzantine Greek νιτρο- (in e.g. νιτροπώλος natron-seller), post-classical Latin nitro- (in e.g. nitro-aereus nitro-aereous adj.), French nitro- (formations in which are found from at least the late 18th cent.), Italian nitro- (formations in which are found from at least the late 19th cent.), German nitro- (formations in which are found from at least the early 19th cent.).Attested in one loan from post-classical Latin (late 17th cent.: see nitro-aereous adj.; compare the adaptation nitro-aerial adj.) and in loans from French (from the late 18th cent.: see e.g. nitromuriatic adj., nitrogen n.) and German (from the early 19th cent.: see nitrobenzide n., nitrosamine n.). English formations are relatively rare before the 19th cent., although the earliest examples are found in the late 17th cent. (e.g. nitro-aluminous adj., nitro-tartareous adj. at sense 1, nitrosulphureous adj., nitro-sulphurious adj.). Compounds in sense 2 are all of late 18th- to mid 19th-cent. origin, but sense 3 continues to be freely productive as a word-forming element in systematic chemical nomenclature.

English formations are relatively rare before the 19th cent., although the earliest examples are found in the late 17th cent. (e.g. nitro-aluminous adj., nitro-tartareous adj. at sense 1, nitrosulphureous adj., nitro-sulphurious adj.).
