Future Middle Infinitive
Introduction
To make the future middle participle, simply add /εσθαι to the future stem. The last syllable of the base takes the accent:
ἔσ/σ/εσθαι > ἔσσεσθαι (Homer) or ἔσεσθαι (Classical)*
λάβ/σ/εσθαι > λήψεσθαι
* σσ becomes σ by geminate reduction.
| BASE | /σ/ or /ε/ | /εσθαι |
