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

Origin: Of multiple origins. Partly a borrowing from Latin. Partly formed within English, by clipping or shortening. Etymons: Latin trachy- ; trachyte n.

Etymology: In sense 1 < scientific Latin trachy- (in e.g. Trachynotus trachynote n. at sense 1) < ancient Greek τραχυ- (in e.g. τραχυφωνία trachyphonia n. at sense 1), combining form of τραχύς rough < the same base as ancient Greek θράσσειν to trouble, disturb. In sense 2 < trachy- (in trachyte n.).Compare French trachy-, German trachy-.

1. combining form, representing Greek τραχύς rough, in a few modern scientific terms.
