Considering words (nominals, verbs and adjectives) we can notice that lexical items derived from a same stem (e.g. -лив-/-лит-) like полив, разлив, перелив, вылить, долить, отлить, etc. suggest certain actions pertinent to some liquid.
Again, considering words with same prefixes, like почёт, помощь, побег, поступь, познать, разнос, раздрай, размазать, etc. we notice that they imply certain scenarios: surficial distribution (po-) or centripetal perfective/telic/progressive distribution (raz-).
The question is, whether these event scenarios, or event structures, are defined by semantics of the words, or by the prefixes.
