22.1 Recall that among –μι verbs, there is a group of four particularly common verbs:
- δίδωμι δώσω give (verb stem: δω-/δο-)
- τίθημι θήσω put, make (verb stem: θη-/θε-)
- ἵστημι στήσω stand (verb stem: στη-/στα-)
- ἵημι ἥσω throw (verb stem: ἡ-/ἑ-)
Observe that the inflection of these verbs in the present middle share the following characteristics:
In the MIDDLE VOICE, these verbs end their stems in a SHORT VOWEL in both singular and plural. (In the ACTIVE VOICE, these verbs end their present tense stems in a LONG VOWEL in the singular and a SHORT VOWEL in the plural forms.)
To this stem is added the ATHEMATIC MIDDLE VOICE personal endings.
The INTERVOCALIC SIGMA found in the 2nd person singular does NOT drop (S 744).
