Etymology

PABA is a short name made from the first letters of para-aminobenzoic acid. A helpful way to remember it is to break the parts: para- means 'next to', amino is a 'part that has nitrogen', benzoic names a common acid group, and acid means 'a type of chemical', so the name itself tells you about the chemical parts of PABA and why it is used in sunscreens and drugs.
