Forms

re-[1] Before vowels and h it appears as red- (redeō, redhibeō), on the model of prōd- beside prō-.[2][3]

Etymology

It is probably inherited from Proto-Italic *wre (“back”),[3][1] whose origin the OLD and Wiktionary call uncertain;[2][1] de Vaan, following Klingenschmitt, traces it to Proto-Indo-European *u̯re (“back”); he calls this the only acceptable etymology proposed so far,[3] and the TLL also finds it probable.[4] The form ⟨red-⟩ was made on the analogy of prōd- beside prō-, and spread by a new division of verbs such as reddō, from earlier *re-di-dō.[3][4]

Cognate with Umbrian re- (“again”) (in ⟨restatu⟩, ⟨revestu⟩) and Albanian rrë- (“back”).[3] The TLL also compares Ancient Greek ἔρρε (érrhe, “go away!”) and Tocharian B wrattsai (“against”).[4]

Semantic evolution

As a verbal prefix it marks movement back or in reverse, withdrawal, the undoing of an earlier process, restoration, response or opposition, separation, and repetition.[2] The sense “again” is the one later languages took over most freely: English re- was taken from Old French re- and directly from Latin from about 1200.[5]

Meanings

Prefix

  1. Back, backwards, in reverse (redeō, revocō).[2][1]

  4. Back to an earlier state, of restoration (renovō).[2]

  6. Apart, of separation (removeō).[2]
  7. Again, of repeated action (repetō).[2][1]

Word family

Usage notes

In verbs with a reduplicated perfect the prefix leads to syncope: reddō for *redidō, repperī for *repeperī.[2]
