Reconstruction:Proto-Indo-European/tréyes

Etymology
Brugmann (1892: 464) suggested original meaning "middle (= protruding) finger", quoting 🇨🇬 and 🇨🇬. This idea was developed by Fay (1910: 416-17), who reconstructed *tri-sth₂-o-s (“tip finger”). In the first component he identified the locative *tr-í- “on-tip”, while the second ("stander") has also to form other finger names, e. g., , , etc.
