  • -είω (-eíō)Epic (etymology #3: verbs that are derived from adjectives in -ής (-ḗs) or neuter nouns in -ος (-os))


There are five main sources:

  1. Primary verbs (present verbs of the simple thematic class in origin) from roots ending in *-w-, *-y-, *-s- with intervocalic loss of this consonant: e.g. ῥέω (rhéō), δέω (déō), ζέω (zéō)
  2. Denominative verbs with *-eyéti, from *-e- (noun thematic vowel) + *-yéti (denominative suffix), usually from nouns or adjectives in -ος (-os) or -ον (-on): e.g. οἰκέω (oikéō) from οἶκος (oîkos), μετρέω (metréō) from μέτρον (métron)
  3. Denominative verbs with *-esyéti, usually from adjectives in -ής (-ḗs) or neuter nouns in -ος (-os): e.g. τελέω (teléō) from τέλος (télos). These often have an alternative form in -είω (-eíō), for instance τελείω (teleíō).
  4. Stative verbs with *-éh₁yeti (stative suffix): e.g. φιλέω (philéō), ἀλγέω (algéō)
  5. Causative or frequentative verbs from o-grade of a root with *-éyeti (causative suffix): e.g. σοβέω (sobéō), φορέω (phoréō)
