The suffix -logy means which of the following?

• A. record, writing
• B. specialist in the study of
• C. study of
• D. condition

Answer: (C)

The suffix -logy denotes the study of. It’s used to name fields that focus on a particular area, such as biology (study of life), cardiology (study of the heart), and dermatology (study of the skin). That makes it the best fit for the idea of “study of.”

It’s helpful to contrast it with similar-looking endings: -graphy means recording or writing (for example, radiography is the process of recording X-rays), -logist refers to a specialist in the study of something (biology student becomes a biologist, cardiologist is a specialist in cardiology), and other endings like -pathy or -itis refer to disease or inflammation rather than the study itself.
