οὐδέ (from Homer down), a neg. disjunctive conjunction, compounded of οὐ and δέ, and therefore properly, equivalent to but not; generally, however, its oppositive force being lost, it serves to continue a negation. (On the elision of ἐ when the next word begins with a vowel (observed by Tdf. in eight instances, neglected in fifty-eight), see Tdf. Proleg., p. 96; cf. WHs Appendix, p. 146; Winers Grammar, § 5, 1 a.; Buttmann, p. 10f) It signifies:
1. and not, continuing a negation, yet differently from οὔτε; for the latter connects parts or members of the same thing, since τέ is adjunctive like the Latin que; but οὐδέ places side by side things that are equal and mutually exclude each other [(?). There appears to be some mistake here in what is said about 'mutual exclusion' (cf. Winer's Grammar, § 55, 6): οὐδέ, like δέ, always makes reference to something preceding; οὔτε to what follows also; the connection of clauses made negative by οὔτε is close and internal, so that they are mutually complementary and combine into a unity, whereas clauses negatived by οὐδέ follow one another much more loosely, often almost by accident as it were; see Winer's Grammar, at the passage cited, and especially the quotations there given from Benfey and Klotz.] It differs from μηδέ as οὐ does from μή [which see ad at the beginning]; after οὐ, where each has its own verb: Matthew 5:15 6:28; Mark 4:22; Luke 6:44; Acts 2:27; Acts 9:9; Acts 17:24; Galatians 1:17; Galatians 4:14; οὐκ οἶδα οὐδέ ἐπίσταμαι, Mark 14:68 R G L marginal reading (others, οὔτε... οὔτε) (Cicero, pro Rosc. American 43, non novi neque scio); cf. Winers Grammar, 490 (456) c.; (Buttmann, 367 (315) note); οὐ... οὐδέ... οὐδέ, not... nor... nor, Matthew 6:26; οὐδείς... οὐδέ... οὐδέ... οὐδέ, Revelation 5:3 (R G; cf. Buttmann, 367 (315); Winer's Grammar, 491 (457)); οὐ... οὐδέ; followed by a future... οὐδέ μή followed by subjunctive aorist... οὐδέ, Revelation 7:16. οὐ... οὐδέ, the same verb being common to both: Matthew 10:24; Matthew 25:13; Luke 6:43; Luke 8:17 (cf. Winers Grammar, 300 (281); Buttmann, 355 (305) cf. § 139, 7); John 6:24; John 13:16; Acts 8:21; Acts 16:21; Acts 24:18; Romans 2:28; Romans 9:16; Galatians 1:1; Galatians 3:28; 1 Thessalonians 5:5; 1 Timothy 2:12; Revelation 21:23. preceded by οὔπω, Mark 8:17; — by οὐδείς, Matthew 9:17; — by ἵνα μή, which is followed by οὐδέ... οὐδέ, where μηδέ... μηδέ might have been expected (cf. Buttmann, § 148, 8; (Winer's Grammar, 474 (442))) Revelation 9:4. οὐδέ γάρ, for neither, John 8:42; Romans 8:7.
2. also not (A. V. generally neither): Matthew 6:15; Matthew 21:27; Matthew 25:45; Mark 11:26 (R L); Luke 16:31; John 15:4; Romans 4:15; Romans 11:21; 1 Corinthians 15:13, 16; Galatians 1:12 (οὐδέ γάρ ἐγώ (cf. Buttmann, 367 (315) note; 492 (458))); Hebrews 8:4, etc.; ἀλλ' οὐδέ, Luke 23:15; ἤ οὐδέ, in a question, or doth not even etc.? 1 Corinthians 11:14 Rec.; the simple οὐδέ, num ne quidem (have ye not even etc.) in a question where a negative answer is assumed (see οὐ, 7): Mark 12:10; Luke 6:3; Luke 23:40; and G L T Tr WH in 1 Corinthians 11:14.
3. not even (Buttmann, 369 (316)): Matthew 6:29; Matthew 8:10; Mark 6:31; Luke 7:9; Luke 12:27; John 21:25 (Tdf. omits the verse); 1 Corinthians 5:1; 1 Corinthians 14:21; οὐδέ εἷς (Winers Grammar, 173 (163); Buttmann, § 127, 32), Acts 4:32; Romans 3:10; 1 Corinthians 6:5 (L T Tr WH οὐδείς); οὐδέ ἕν, John 1:3; ἀλλ' οὐδέ, Acts 19:2; 1 Corinthians 3:2 (Rec. ἀλλ' οὔτε); 1 Corinthians 4:3; Galatians 2:3. in a double negative for the sake of emphasis, οὐκ... οὐδέ (Buttmann, 369 (316); Winer's Grammar, 500 (465)): Matthew 27:14; Luke 18:13; Acts 7:5.
