From re- + dō (“give”). The double -dd- is a remnant of the reduplication that was lost in the base verb.
reddō (present infinitive reddere, perfect active reddidī, supine redditum); third conjugation
For the 1st person singular future active an old form reddĭbō is attested, which is the regular product of *reddăbō undergoing vowel weakening.
