As a personal prenomen this name is a dialectic abridgment of "Abun" ("Abin," "Rabin"; see Jastrow, "Dictionary," 147a; compare Pesiḳ, 30:192b; Yer. Ḥag. 1:76c; Yer. Suk. 5:55d), and appears exclusively in Palestinian literary sources (Yer. Ter. 8:45c; Yer. Pes. 3:29d; Yer. Sheḳ. 4:48b; Yer. Yeb. 3:4c). Several amoraim so cited are mentioned under the full name as it appears in the Babylonian Talmud (see, for example, ABIN B. ḤIYYA, ABIN B. KAHANA); and a Palestinian scholar of the fourth century is cited once under the name of "Bun b. Bisna" (Yer. Yeb. 4:7b), and once (ib. 1:2d) under that of "Abun b. Bizna."
