Some Greek etymologies

Five short articles are presented offering, in some, new etymological suggestions (§§ 1. μάχομαι ‘fight’, μισθός ‘reward’, 2. βούλομαι ‘want, wish’ : Slavic *gòlъ ‘bare, naked’, 4. εἵλη ‘warmth, heat of the sun’), in others, comments on existing etymologies (§§ 1. μισθός ‘reward’, 3. οὖτα ‘wound’, 5. ὄνυξ ‘nail’ and delabialization by *l in North and East Germanic). Two of the items present alternatives to reconstructions with PIE *a (§§ 1, 3).
