peroxo-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Some degree of stress is always maintained on the second syllable. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. peroxonitric Brit.

/pəˌrɑksoʊˈnaɪtrɪk/.

Origin: Formed within English, by derivation. Etymons: per- prefix, oxo- comb. form.

Etymology: < per- prefix + oxo- comb. form, after peroxide n. Compare peroxy- comb. form.Found in a number of formations exemplified below and also in peroxonitric adj.

Chemistry.

Esp. in inorganic chemistry: designating, containing, or involving a peroxide group. Cf. peroxy- comb. form.
