The Μι-Conjugation

355. The distinction between the ω- conjugation and the μι- conjugation applies only to the present system. In the μι- conjugation the present stem does not end in -ο:ε-, and the fuller endings -μι, -ς, -σι,
-ᾱσι, -σαν (§ 263) are used. There are two classes.

356. (1) Nasal Class (cp. § 261): The suffix -νυ:ῡ-, after a vowel

-ννυ:ῡ-, is added to the verb stem.

357. (2) Root Class: The present stem is the verb-stem, always a root, sometimes reduplicated.
