▪ I.ap- prefix¹assimilated form of L. ad- ‘to,’ bef. initial p-, as L. ad-proba-, ap-proba-. In OFr. this ad- ap- was, by regular phonetic law, reduced to a- (as in the separate word ad), and in this form the Fr. words were adopted in Eng., as a-part, a-pere, a-ply, a-pose, a-prise, a-prove. In imitation of the Latin forms, the scribes began to double the p in Fr. spelling in 14th c., and in Eng. in 15th, though, in speech, the prefix is still really a- (cf. əˈpɛnd, ˈæplɪkənt). By mistake ap- was also substituted for a- in several words where it had a different origin, as appair, appeach: see ad- prefix 2, a- prefix 10.▪ II.ap- prefix²in words of Greek origin, for ἀπ' the shortened form of ἀπό ‘off, away,’ bef. a vowel, as in ἀπ-αγωγή ap-agoge: see apo-.▪ III.ap-, prefix³[Welsh ap, from map son, used in pedigrees and a common prefix in surnames, as Apjohn, Aprys; cf.

patronymic prefix in Welsh names, earlier map "son," cognate with Gaelic mac. Since 17c. merged into surnames (Ap Rhys = Price, Ap Evan = Bevan, etc.).

It is said that a Welshman who evidently was not willing to be surpassed in length of pedigree, when making out his genealogical tree, wrote near the middle of his long array of 'aps' -- "about this time Adam was born."
