ptero-comb. form

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

Inflections: Before a vowel pter-.

Origin: A borrowing from Greek. Etymon: Greek πτερο-.

Etymology: < ancient Greek πτερο-, combining form (in e.g. πτεροϕόρος feathered, winged) of πτερόν feather, wing < the same Indo-European base as feather n. Compare scientific Latin Ptero- (formations in which are found from the mid 18th cent.), French ptéro- (formations in which are found from the beginning of the 19th cent.), German Ptero- (formations in which are found from the second half of the 19th cent.).Attested earliest in the late 18th cent. in the Latin loan Pterocarpus n., and subsequently in a number of loans and adaptations of scientific Latin and French terms, all belonging to scientific vocabulary. Formations within English are found from the first half of the 19th cent., apparently earliest in pterotheca n. Combining with second elements ultimately of Greek origin.

Of, relating to, or shaped like a wing or feather; winged, feathered.
