Word History

Etymology

Noun

short for thyroid gland — more at thyroid entry 2

Adjective

borrowed from New Latin thyroīdēs, shortened from thyreoīdēs, borrowed from Greek thyreoeidḗs "shield-shaped (of the cartilage in the larynx)," from thyreós "stone put against a door to keep it shut, oblong shield" (probably originally noun derivative of an adjective meaning "shaped like a door," from thýra "door" + -eos, suffix of appurtenance) + -oeidēs -oid entry 2 — more at door

Note: The form thyroīdēs presumably arose because the word was taken as directly derived from thýra "door," rather than from thyreós. The word thyroeidḗs "like a door" is marginally attested in ancient Greek.
