Stress is usually determined by a subsequent element and vowels may be reduced accordingly; see e.g.
omohyoid adj. and n.Origin: A borrowing from Greek. Etymon: Greek ὠμο-.
Etymology: < ancient Greek ὠμο-, combining form (in e.g. ὠμοπλάτη : see omoplate n.) of ὦμος shoulder, cognate with classical Latin umerus (see humerus n.). Compare post-classical Latin omo- (formations in which are found from at least the 4th cent.), French omo- (formations in which are found from at least the early 19th cent.).Rare before the 19th cent. Earliest in Middle English in the loan omoplate n., ultimately from ancient Greek. Apparently not otherwise attested until the late 18th cent. in the scientific Latin loan omohyoideus n. Chiefly in classical loans, although English formations are found from the mid 19th cent. (e.g. omohyoid adj., omohyoid n.).
