In sentences with the combination “verb + preposition + noun phrase” is there a procedure to identify whether it is a phrasal verb + object or a verb + prepositional phrase? or does it solely depend on the meaning?
For example consider these two examples from which I think the first one has a phrasal verb and the second one a prepositional phrase:
She always talks about her childhood friends
She fell from her bicycle
I think in the first example “talk about” is the verb and “her childhood friends” the object. As for the second example, I think “fell” should be the verb and “from her bicycle” a prepositional phrase.
The two examples seem a lot similar to me and the fact that one has an object and one doesn’t is somehow unexplainable to me.
