Thayer's Greek Lexicon
ἀποσυνάγωγος, ἀποσυναγωγον (συναγωγή, which see), excluded from the sacred assemblies of the Israelites; excommunicated, (A. V. put out of the synagogue): Joh_9:22; Joh_12:42; Joh_16:2. Whether it denotes also exclusion from all contact with Israelites (2Es_10:8), must apparently be left in doubt; cf. Winers (or Riehm) RWB under the word Bann; Wieseler on Gal_1:8, p. 45ff (reproduced by Prof. Riddle in Schaff's Lange's Romans, pp. 304-306; cf. B. D. under the word ). (Not found in secular authors.)

Moulton & Milligan — Vocabulary of the Greek NT
ἀποσύναγωγος [page 70]
ἀποσύναγωγος is not found in prof. auth. (Grimm) : it is as naturally not quotable from our sources. This is of course just the sort of word that would have to be coined for use in the Jewish community.
