please tell me how do I know what is transitive verb or intransitive verb
Transitive verbs normally refer to an action performed by the subject on something or someone else, while intransitive verbs (reflexive verbs) don't.

She advises with a friend (She gets advice from a friend)

I mixed those up. I run is intransitive and I run a report is transitive... sorry!
