So you have the perfective and imperfective form of verbs, e.g. дарить и подарить. This is sometimes determined by the prefix, as shown above. But verbs can also have other prefixes which determine meaning (I’ll refer to these as special “prefix meanings”, as I don't know what else to call them), e.g. ходить и уходить.
So, does this mean that only the perfective form of the verb can have a special “prefix meaning”, or does it just mean that verbs for which the prefix changes for the perfective (first example) cannot have a special “prefix meaning”. Is it possible for imperfective verbs to have a "prefix meaning"? or would giving an imperfect verb a prefix automatically make it a perfective verb?
