Thayer's Greek Lexicon
σύζυγος (L T Tr WH συνζυγος (cf. σύν, II. at the end)), συζυγον, (συζεύγνυμι), yoked together; used by Greek writers (from Aeschylus down) of those united by the bond of marriage, relationship, office, labor, study, business, or the like; hence, a yoke-fellow, consort, comrade, colleague, partner. Accordingly, in Php_4:3 most interpreters hold that by the words γνήσιε σύζυγε Paul addresses some particular associate in labor for the gospel. But as the word is found in the midst of (three) proper names, other expositors more correctly take it also as a proper name ((WH marginal reading Συνζυγε); see Laurent, Ueber Synzygos in the Zeitschr. f. d. Luther. Theol. u. Kirche for 1865, p. 1ff (reprinted in his Neutest. Studien, p. 134f)); and Paul, alluding (as in Phm_1:11) to the meaning of the word as an appellative, speaks of him as 'a genuine Synzygus', i. e. a colleague in fact as well as in name. Cf. Meyer and Wiesinger at the passage; (Hackett in B. D. American edition under the word ).

Moulton & Milligan — Vocabulary of the Greek NT
σύνζυγος (~ σύζυγος ) [page 607]
yoke-fellow. We can produce no evidence for σύνζυγος as a proper name, though its use as such in Php_4:3 seems probable (WH marg.) : see Kennedy EGT ad l . For its use as an appellative Thieme (p. 32) cites the Magnesian graffito 328 (prob. i/A.D.) σ ]ύζυγοι Βαίβιος Κάλλιπος : cf. 321.
