Etymology: "Thyro-" is not a standalone English word but a combining form, a prefix used in medical terms relating to the thyroid gland. It comes from the Greek "thyreoeides", meaning "shield-shaped", which itself came from "thyreos", a large oblong shield. The gland was named for its shape: the two lobes of the thyroid cartilage in the throat resemble the curved shields that Greek soldiers carried. The Greek element was adopted into scientific Latin and then into English medical vocabulary, where it appears in words such as "thyroiditis" and "thyrotoxicosis". Its usage is a product of modern medicine rather than ancient Greek practice: the gland itself was not described in detail until the 17th century, and the names built from this root were coined in the 18th and 19th centuries, when physicians needed precise terms for the glands and their diseases.
