Which root means iris?

Which root means iris?

• A. lingu
• B. neuro
• C. irid
• D. jejun

Answer: (C)

Understanding how roots map to body parts helps decode medical terms. For the iris, the combining form is irid- (often written as irido- in some terms). That root shows up in words like iritis or iridotomy and specifically points to the iris of the eye. The other roots point to different structures: lingu- relates to the tongue or language, neuro- to nerves, and jejun- to the jejunum, a part of the small intestine. So irid- is the correct root for iris.
