The meanings of some phrasal verbs can be guessed sometimes; like go after, give back, find out, etc.
1) Go after her quickly.
2) Give my wallet back.
3) Find out what I have lost.
The reason being (how I understand) from the context, it is clearly understandable what might these phrasal verbs mean. Sometimes they are same with the meaning of the verb itself, just a little addition/subtraction of the meaning, but the theme remains almost constant.
Again some phrasal verbs do not really mean what we guess it could be from the context; For example, put up with, bring up, chip in, etc.
1) I can not put up with you.
2) She brought him up.
3) If everybody chips in I can complete the work by tomorrow .
It is hard to guess meanings of these phrasal verbs even from the contexts and usages. So in these cases how can we guess the meanings of those?
