““ἀλλ᾽ οὐδὲ τούτων στερήσονται” but no; even of these shall they be deprived” X. A. 1.4.8, ““ὅτ᾽ οὐδ᾽ οὕτω ῥᾴδιον ἦν” when besides it was not so easy” I. 18.65 (= καὶ οὐ also not). With οὐδ᾽ ει᾽ (ἐά_ν) not even if οὐ belongs with the main clause, while δέ even goes with the dependent clause. Thus, ““οὐδ᾽ ἂν εἰ βούλοιντο, ῥᾳδίως πονηροὶ γένοιντο” even if they wished, they could not easily become wicked” X. C. 7.5.86 (= καὶ εἰ βούλοιντο, οὐκ ἂν γένοιντο). Similarly with a participle: ““οὐδὲ πεπονθὼς κακῶς ἐχθρὸν εἶναί μοι τοῦτον ὁμολογῶ” I do not admit that this man is my enemy even though I have been ill-used” D. 21.205.
