The prefix esthesio- means which of the following?

• A. Feeling/Sensation
• B. Pain
• C. Sight
• D. Hearing

Answer: (A)

Esthesio- denotes sensation or feeling, coming from a Greek root meaning perception. It’s used in medical terms that describe sensing or perceiving stimuli, such as esthesiometer (an instrument that measures sensory thresholds) and esthesiology (the study of sensation and perception). A helpful way to see it is through anesthesia, which means without sensation—the root here points to sensation, while the prefix an- indicates without. The other modalities—pain, sight, and hearing—use different roots (pain with odyn- or -algia; sight with opt-/opto-; hearing with acoust-/aur-/audi-). So esthesio- is specifically about sensation.
