common (English)

Where does "common" come from?

The word 'common' traces its roots back to the Proto-Indo-European *mey-, meaning 'to exchange or change'. It evolved through the Latin commūnis, which described things held collectively, before passing through Old French and Anglo-Norman into Middle English. By entering the English language, it eventually displaced native terms like 'mean' to become our standard word for things shared, ordinary, or public.
