oxy-comb. form¹

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

Origin: A borrowing from Greek. Etymons: Greek ὀξυ-, ὀξύς.

Etymology: < ancient Greek ὀξυ-, combining form (in e.g. ὀξύβαϕον oxybaphon n.) of ὀξύς sharp, keen, acute, pungent, acid, cognate with ear n.²First attested in a number of borrowings of Latinand Greek words from the Old English period onward, earliest in oxymel n. In many early examples the element has the sense ‘containing vinegar; acidic; sour’, especially in medical terminology (as e.g. oxycroceum n., oxyrrhodine n., oxysaccharum n.), although compare in more domestic vocabulary oxoleum n. and oxybaphon n. Loans and adaptations immediately from French are also found in medical terminology showing this sense, earliest in oxycrate n.; compare also (in chemistry) oxygen n. The English formations given at sense 2 below are also antedated by loans and adaptations from Latin and Greek in biology and zoology, in which the element has the sense ‘sharp, pointed’: early examples include oxyrhynchus n. and oxycedar n. in the 17th cent. Borrowings and adaptations immediately from French are also found from the mid 19th cent. in this sense, as e.g. oxystome n. The same sense of the combining form is attested in other technical fields: compare from the 16th cent. in geometry oxygonium n. and from the 17th cent. in rhetoric oxymoron n. English formations are increasingly common in all senses from the mid 19th cent., usually with second elements ultimately of Greek origin. Compare post-classical Latin oxy-, French oxy- (formations in which are found from the late 18th cent.), German oxy-, etc.

oxy-comb. form²

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

Etymology: Shortened < oxygen n. Compare oxo- comb. form, oxy adj.²Attested in a large number of English formations in chemistry from the late 18th cent., earliest in oxymuriated adj., oxymuriatic adj., and oxymuriate n. Formations in pharmacology are also occasionally attested from the second half of the 20th cent. (as e.g. oxytetracycline n., oxazepam n., oxamniquine n.). Loans and adaptations from French (e.g. oxamide n., oxylithe n.) and German (e.g. oxazole n., oxychromatin n., oxyproline n.) are occasionally found from the first half of the 19th cent. Combines chiefly with elements ultimately of classical origin, although formations with second elements of other origins are also found, especially in sense 3: compare e.g. oxy-alcohol n. at sense 3a, oxy-salt n., oxy-coal-gas n. at sense 3a, oxy-fatty adj., etc. Compare French oxy- (formations in which are found from the beginning of the 19th cent.), German oxy- (formations in which are found from at least the first half of the 19th cent.).

单词	oxy-
释义	oxy-comb. form¹ Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Origin: A borrowing from Greek. Etymons: Greek ὀξυ-, ὀξύς. Etymology: < ancient Greek ὀξυ-, combining form (in e.g. ὀξύβαϕον oxybaphon n.) of ὀξύς sharp, keen, acute, pungent, acid, cognate with ear n.²First attested in a number of borrowings of Latinand Greek words from the Old English period onward, earliest in oxymel n. In many early examples the element has the sense ‘containing vinegar; acidic; sour’, especially in medical terminology (as e.g. oxycroceum n., oxyrrhodine n., oxysaccharum n.), although compare in more domestic vocabulary oxoleum n. and oxybaphon n. Loans and adaptations immediately from French are also found in medical terminology showing this sense, earliest in oxycrate n.; compare also (in chemistry) oxygen n. The English formations given at sense 2 below are also antedated by loans and adaptations from Latin and Greek in biology and zoology, in which the element has the sense ‘sharp, pointed’: early examples include oxyrhynchus n. and oxycedar n. in the 17th cent. Borrowings and adaptations immediately from French are also found from the mid 19th cent. in this sense, as e.g. oxystome n. The same sense of the combining form is attested in other technical fields: compare from the 16th cent. in geometry oxygonium n. and from the 17th cent. in rhetoric oxymoron n. English formations are increasingly common in all senses from the mid 19th cent., usually with second elements ultimately of Greek origin. Compare post-classical Latin oxy-, French oxy- (formations in which are found from the late 18th cent.), German oxy-, etc. 1. Medicine.
