re
UK: riː | US: riː
prefix. again; back (used to indicate repetition or return to a previous state)
The prefix "re-" originates from Latin, where it functioned as an inseparable particle meaning "again" or "back." It was adopted into Old French and later Middle English, retaining its core sense of repetition or reversal. For example, "rebuild" (build again), "return" (turn back), and "review" (view again) all demonstrate its enduring role in forming words with cyclical or restorative meanings.
