↔️ Contronyms

Some English words quietly contain their own opposites. Cleave can mean to split apart or to cling tightly. Sanction can mean to approve or to punish. These words are called contronyms (or auto-antonyms). Context almost always makes the intended meaning clear, yet the double life of each word remains surprising.

The words below are among the most useful and frequently noticed. Each entry shows both meanings, gives realistic examples, and notes how speakers usually tell the two senses apart.
