A type of medicine that helps to reduce pain and lower fever.
I took acetaminophen to help with my headache.
Acetaminophen is formed from "acetyl" (from the Latin "acetum", meaning vinegar) and "aminophenol" (which combines "amino" from the Greek "aminon", meaning nitrogen-containing group, and "phenol" from the Greek "phaino", meaning to show or appear). The word refers to a compound that contains an acetyl group and an amino group attached to a phenol structure, commonly used as a pain reliever and fever reducer.
Think of 'acetyl' as relating to vinegar and 'aminophenol' as a combination of nitrogen and a phenol structure, which helps you remember that acetaminophen is a compound used for relieving pain.
