I am curious as to the exact definition of a transitive verb. I had been under the impression that it is a verb which takes a direct object; however, I read something in 501 English Verbs which gives the impression that a transitive verb is one which is followed by an object (direct OR indirect). Also, is there an easy way to memorize the verb lists (verb + gerund and/or infinitve)? Students often ask me this. Thank you!
