What is the difference between the imperative forms of a Impf Verb and a corresponding Pf Verb ? I can't imagine what kind of meaning an Impf verb could express. Could anybody give me more examples of this usage ))) Thank you ))) e.g. Спросите кого-нибудь ! (I can understand) Спрашивайте кого-нибудь ! (???) пей ! - Drink it! выпивай - ???
