Etymology

The word dermatologist combines Greek roots to describe a skin specialist. Derma (skin) has been used since ancient Greek medicine, while -logist emerged in scientific terminology to denote experts. The fusion reflects the systematic naming of medical professions, where -logist pairs with organ/system roots (e.g., cardiologist). The term solidified in the 19th century as dermatology became a distinct medical discipline.

  3. Dermatologists often perform skin cancer screenings.

  4. My dermatologist recommended sunscreen for daily use.

  5. He trained for years to become a board-certified dermatologist.
