Future -σειν -σεσθαι -θήσεσθαι
1st Aorist -σαι -σασθαι -θῆναι

Attic dialect; Homeric variant forms noted where they diverge (e.g. -οισι, -ῃσι, -αων). All forms show stem endings only — prefix the appropriate verb/noun base. Augment = ε- prefix for verbs beginning with a consonant; initial vowel lengthens for vowel-initial stems.
