Which suffix denotes "worm"?

Which suffix denotes "worm"?

• A. -graph
• B. -helminth
• C. -graphy
• D. -gram

Answer: (B)

Understanding suffixes that name what kind of organism is involved helps you decode terms. The ending that designates a worm is -helminth, as in helminth and helminthology, used for parasitic worms such as nematodes and cestodes. In contrast, -graph refers to an instrument or device that records something (for example, an electrocardiograph), -graphy means the process or field of recording (like radiography, the act of recording with X-rays), and -gram denotes a written record or a unit/diagram (such as a cardiogram or kilogram). Therefore, -helminth is the suffix that denotes worm.
