pur-

Forwards, out, or away.

Old French or Anglo-Norman French, from Latin por‑, pro‑.

Such words are closely related in origin and sense to those beginning with pro‑ (see pro‑¹). Examples include pursue (Anglo-Norman French pursuer, from an alteration of Latin prosequi, prosecute), purloin (Anglo-Norman French purloigner, put away); purport (Old French purporter, from Latin portare, carry or bear); purchase (Old French pourchacier, seek to obtain or bring about).
