Root Explanation

Phenacetin is formed from "phen-" (from Greek "phaino", meaning to show or to appear) and "acetin" (derived from acetic acid, which is a component of vinegar). The word refers to a compound that shows or appears to have analgesic properties, as it was used as a pain reliever.

Memory Tip

Think of 'phen-' meaning to 'show' or 'appear' and 'acetin' relating to a component of vinegar, which helps you remember that phenacetin is a compound that appears to relieve pain.
