Hello. According to Wiktionary, 'abstract verbs are always imperfective in aspect'. However, I noticed that ходи́ть (abstract and imperfective) does have a perfective version, сходи́ть. For this verb, wiktionary offers the following example: Мне нужно сходить в банк. - I need to go to the bank (and come back). Isn't the idea of 'going and coming back' a feature of abstract verbs? So, ultimately, isn't сходить an abstract perfective verb?
Isn't побегать (the perfective counterpart to бегать) another example of an abstract perfective verb?
Isn't побегать (the perfective counterpart to бегать) another example of an abstract perfective verb?
