Root Explanation

Thyreoid → It is derived from the Greek word "thyreoeides" (meaning shield-shaped), which is a combination of "thyra" (meaning door or opening) and "eidos" (meaning form or shape). The term refers to the shape of the thyroid gland, which resembles a shield or door.

Memory Tip

Imagine a shield ('thyreoeides') that represents the shape of the thyroid gland — this helps you remember that 'thyreoid' refers to something shield-shaped.
