A dependent clause (a sentence fragment set off by commas, dontcha know) helps you explore your story by moving you deeper into the sentence. It allows you to stop and think harder about what you've already written. Often the story you're looking for is inside the sentence. The dependent clause helps you uncover it.
Janet FitchSo much wanting and longing, clutching, desiring, passion and hatred and terrible need. Here, death was suitable, there was room for it, the grip of life's relentless urges slackened, replaced by this icy simplicity. This wasnt her death. It was his. That was the sad and honest truth. Though it would stay with her, it would be more like a black onyx heart on a silver chain, worn privately, under her clothes, close to her body, all her life. The guilt, the beauty, everything. It wasnt over, it had only begun. Well ok then, Okay.
