In comparison to the verb лежать ( stem = легЯ-: historically e-stem verbs with a preceding VELAR CONSONANT) this verb has irregular formations for 1st pers sing. non-past,3rd pers. pl. non-past, imperative formations, and the pres. act. part similar to the verb мочь (stem = мог-).

Irregular stems occur for Imperative forms, just as with the imperfective бить; however, note that the stress for all forms falls on the perfectivizing prefix вы-. вы- with some regularity assumes the stress when attached to a non-productive imperfective stem. When the stem extension -вай-, denoting a general/iterative imperfective state, is attached to perfective verb stem with the prefix вы-, the stem extension syllable assumes the stress for all forms which follow the conjugation model of знать. (e.g., выбивать)

The normal correlation of non-past endings and the past extension vowel does not occur with this verb. When we compare the following forms (RUSSIAN: гнуть, гну, гнешь . . .--to bend, drive; гонять, гоняю, гоняешь . . .--to drive; OLD RUSSIAN: гънати, жену, женешь . . .; гонити, гоню, гонишь . . .) one could infer that the non-past forms are derived from the the Old Russian гонити. However, the verb спать reflects this same disparity between the non-past forms and the past extension vowel (сплю, спишь . . .). Thus, the stem гОнА- will be said to select irregular non-past endings.

давай- is considered to be the primary stem for this verb with the past forms, the imperative forms and several non-past participial forms able to be derived from it. Non-past forms are postulated to be derived from the secondary, irregular stem дай-.

This verb is classified historically as "athematic", i.e., it lacks a theme vowel in the singular non-past formations. In this project ед- is postulated as the basic stem. However, the past participle formations follow the pattern of other stems which end in д and have unstressed infinitive endings wherein the final д is lost before the ending which starts with the consonant в. Since this project applies the effects of stress as the final rule, there seems to be no way to predict the occurrence of these endings.
