Stuck again with the role of 'after'...
Please consider the following two sentences:
1. "The bridge appeared after the turn."
2. "The bridge appeared after I had taken the turn."
What is the role of "after" in the above sentences? "After the turn" appears to be a prepositional phrase (adverb, modfiying the verb "appeared").
What about the second sentence? Conjunction or preposition? If the answer is "preposition", then what is the object of this preposition? How can it be a preposition when there is a subject in the clause that immediately follows?
Here I disagree with Lewis. In the first sentence, "after" is a preposition, and "the turn" is a noun phrase functioning as the object of the preposition. In the second sentence, "after" is a subordinating conjunction beginning the subordinate clause "after I had taken the turn."
A clause is composed of a subject and a verb. When we add a subordinating conjunction, it makes the clause subordinate. For example, "He said," is a clause. "What he said," is a subordinate clause since we've added the subordinating conjunction "what."
In your sentences, "I had taken" is the subject/verb pair, "the turn" is the direct object (what had you taken?). After is connecting that clause to the first clause "The bridge appeared." So, in this sense, "after" is a subordinating conjunction turning the second clause into an adverb clause that explains when the bridge appeared.
