Hyoid

/ˈhaɪɔɪd/adjective

The Greek roots

the letter upsilon
+
εἶδος
eîdos
form, shape

Literally: upsilon shaped

The story of the word

Named for a letter: the bone is shaped like an upsilon, so ὑοειδής, upsilon-like. It is the only bone in the body that articulates with no other bone, slung in the neck by muscle alone, which is why a fractured hyoid is read at autopsy as a sign of strangling. Deltoid and rhomboid come from the same anatomical habit of naming a thing after the figure it resembles.
