Phrasal Verbs consist of a verb plus a particle:
verb + adverb or verb + preposition or verb + adverb + preposition.
The meaning of this combination is mostly very different from the verb and the adverb or preposition alone.
There are no rules that might explain how phrasal verbs are formed correctly - all you can do is look them up in a dictionary and study their meanings.
In fact many phrasal verbs are metaphorical, and if you understand the metaphors they use, it will be easier to understand and remember their meanings.
Phrasal verbs are mainly used in spoken English and informal texts.
Many phrasal verbs are transitive, meaning that they take an object. Other phrasal verbs can stand alone (intransitive verbs).
Some phrasal verbs are separable (the verb and the preposition can be separated, putting the object in the middle), while others are inseparable (the object must come at the end because the verb and the preposition must stay together).
Separable verb:
Correct: Put on your coat.
Correct: Put your coat on.
Inseparable verb:
Correct: Get on a bus
Incorrect: Get a bus on

How to remember English phrasal verbs?

The first thing to do with phrasal verbs is to learn them as phrases and not only as separate words. Try to remember them as if they were a single verb.
The second thing that will help you is to remember them in groups.
For example, make a list of phrasal verbs with the word get in them and try to remember them.

You will find it easier, if you put them in groups of verbs with the same preposition. For example, phrasal verbs including the word ON. It is useful to group them on the basis of their meaning and using.
The third thing that will help you learn phrasal verbs is to make up or write sentences that will help you remember how they are used.
The fourth important thing about phrasal verbs is to remember if there are any other prepositions which always follow them.
For example: "I get ON well WITH my sister."
