In this grammar book I am working through, prepositions are defined as words that connect certain nouns and pronouns (AKA objects of prepositions) to clauses. However, in the following sentence, I am not sure how this is the case:
The man in the blue shirt stood in front of the store.
I understand that the object of the preposition is shirt, but how come it is connected to "The man" if "The man" is clearly not a clause? Similarly, how does the other object of the preposition (store) connect to "The man" (since it's not a clause)?
