af-, prefix1. Assimilated form of L. ad- to, bef. initial f-, as in af-fectus, af-flātus, af-fluentia. Reduced in OFr. to a-, and so adopted in Eng. But artificially restored in Fr. spelling in 4–5, whence extended to Eng. in 5–6; as in affair, affiance, affront, early Eng. afaire, afiaunce, afront. In all mod. words from L., aff- has been written from the first, though only one f- is pronounced.2. While the words from OFr. were being refashioned after L. spelling, af- was substituted for a- in various words where it did not represent L. af-, as in a(f)fray, a(f)fright; see ad- 2.
af- /af, unstressed əf/ prefix (rarely productive).Assim. form of Latin ad- before f. In Old French, Latin aff- was reduced to af-, which appears in early adoptions, but in later French, and hence in English, aff- was restored by Latinization, as affair, affront. Hence extended to some words of different origin, as affray, affright.
