Well, дать and давать are a imperfective and perfective pair. Same meaning. As for other prefixed versions, usually they equate to English give, followed by a preposition/adverb. Дать--Give...Выдать--Give out. (вы- carries the meaning of out). If you understand what the word по means, you'll probably learn what подать means. по often is used just to turn imperfective verbs into their perfective counterpart. As a prefix focuses usually on the absolute start of actions. (though the preposition has to do with "dispersion").https://en.wiktionary.org/wiki/%D0%B...B0%D1%82%D1%8C (links to подавать as well)
