Which combining form means angle at the end of the eyelid?

• A. Cantho-
• B. Trans-
• C. -cele
• D. Semen

Answer: (A)

The angle at the end of the eyelid is called the canthus. The combining form cantho- comes from a Greek word for corner or angle and is used to name structures and procedures related to that eye region, such as canthoplasty or canthotomy. That makes cantho- the correct choice for “angle at the end of the eyelid.” Trans- is a prefix meaning across or through, which isn’t specific to the eye. -cele is a suffix meaning hernia or swelling, not a field for eye anatomy. Semen is a root referring to semen, unrelated to the eye.
