Is It True That Reply Means ‘Fold Again’? The Real Origin of Reply
No, the idea that English reply comes from the modern prefix re‑ plus the verb ply (‘to fold’) is a folk etymology. The word entered English from Old French replier, itself from Latin re‑ + plicare ‘to fold back’. The myth gained traction online in the 2000s, but scholarly sources trace reply to medieval French, not a literal English “re‑ply”.
