comma splice or apposition: he slowed at the turn, the turn that

[ProtomanMt]

"He followed the road back and slowed at the first turn, the turn that brought the cabins into view."

Are these two separate sentences? If the later one, which I think is a sentence, is not a sentence, then what type of phrase/clause is it?

It looks to me like an appositive, which would make it a noun phrase.

 

[JB]

It cannot be a complete sentence because it
lacks a subject and predicate (verb).
I agree with xqby. The entire phrase "the turn that brought ... view" functions like an adjective, describing "first turn".

I agree that it is a noun phrase, because you could say:
The turn that brought the cabins into view (Subject)
was (Verb)
[whatever you want to add, for example]
the first turn he came to
clearly marked with a sign
dangerously sharp,
etc.

Yes, it's an appositive, an appositive of the kind that repeats the noun and adds an adjective phrase to further describe it.

It's not a comma splice as the phrase following the comma is not an independent clause.
