-ptercomb. form

Some degree of stress is attracted to the syllable immediately preceding this combining form and vowels may be reduced accordingly; see e.g. orthopter n.²

Origin: A borrowing from Greek. Etymon: Greek πτερόν.

Etymology: < ancient Greek πτερόν wing (see ptero- comb. form). Compare French -ptère (formations in which are found from at least the late 18th cent. in sense 1, and from the second half of the 19th cent. in sense 2); with sense 1 compare also scientific Latin -ptera (see note).Scientific Latin -ptera ( < ancient Greek -πτερα , neuter plural of -πτερος : see -pterous comb. form) forms taxonomic names of orders and suborders of insects. Formations in it are found from the mid 18th cent. English words containing the combining form -pter frequently have an antecedent in French -ptère , as neuroptère (1754: see neuropter n.), hélicoptère (1861 or earlier: see helicopter n.). In sense 1, not freely productive in English, but available in principle to form terms corresponding to scientific Latin names in -ptera, and so used from the early 19th cent.
