Root Explanation

Trinitrotoluene is formed from "tri-" (meaning three), "nitro" (from Latin "nitrum", meaning saltpeter or nitrate), and "toluene" (from the Spanish "tolueno", referring to a type of aromatic hydrocarbon derived from the resin of the Tolu tree). The word describes a compound that contains three nitro groups attached to a toluene molecule.

Memory Tip

Think of 'three' ('tri-') nitro groups being added to a 'toluene' base — that's how trinitrotoluene is formed.
