A subordinating conjunction introduces a dependent clause in a complex sentence.
Here is an example:
I checked my emails when I arrived home.
The clause <em>I checked my emails </em>is independent, and <em>when I arrived home </em>is dependent, and it starts with a subordinating conjunction <em>when.</em>
The stage in the writing process when you check your work to verify detail and a valid thesis statement is the: Revising stage. During the editing stage you check your essay for any type of grammar mistakes and faults. Hope that helps.
