Etymology: "Thyroids" is the plural of "thyroid," so the gland's name comes from a Greek word for a shield. Ancient Greek "thureos" meant an oblong shield, and "thyreoeidēs," meaning "shield-shaped," was built from it with the suffix "-eidēs," "-like." Scholars writing in New Latin borrowed that compound as "thyreoīdēs," and English took it up as "thyroid." The name refers to the gland's shape. Its two lobes, one on each side of the windpipe, were compared to the large, curved shields of Greek soldiers, and the Greek-derived term stuck. The shape looks nothing like a shield to most people today, but the naming logic is the same as in any anatomical term built from a visual comparison.
