As the common definition runs, an intransitive verb doesn't need an object as in "I run in the street." But my question is why some verbs are labeled intransitive, and at the same time, they take a preposition followed by an object: For example, agonize plus over/about and then an object:
- She agonized about what she should do.
Why shouldn't we call it a transitive verb? Other examples: apologize to, object to
