Etymology

Paraquat comes from two parts, para and quat. The para part shows where parts of the molecule sit on its chemical ring and the quat part comes from 'quaternary', linked to 'quarter' meaning 'four', so the name tells scientists about the molecule's shape and its charged parts, which is why paraquat is a very strong, poisonous weed killer.
