I am confused on how to identify a sentence as a complex sentence or a simple sentence. The sentence is "The first recorded trip to the Yellowstone geysers was made in 1807 by John Colter." I think it is simple...but am not sure if there is a subordinate clause in there or not

Answer 1

The first thing to do is to identify the clauses, both independent and dependent. Remember that a clause has a subject and a verb.

The first recorded trip to the Yellowstone geysers was made in 1807 by John Colter.

In this sentence, there is one subject and one verb; therefore, it's a simple sentence.

one independent clause = simple
two independent clauses joined correctly = compound
one independent and one dependent clause = complex
two independent clauses joined correctly plus one dependent clause = compound-complex
