What is a complex sentence?

According to Grammarly, a complex sentence is one of the four sentence types: simple sentences, complex sentences, compound sentences, and compound-complex sentences.  Complex sentences contain a dependent clause, also known as subordinate clauses. These are clauses that cannot be a complete sentence on their own, and are considered a sentence fragment without an independent clause. Many complex sentences contain a comma, have an adjective clause or noun clause, or follow an if-then structure. These sentence structures form a complete thought, as opposed to a simple sentence that simply gives a short answer. These types of sentences utilize a coordinating conjunction or subordinate conjunction with punctuation like a semicolon, comma, or colon. The numerous types of sentence structure may seem confusing, but they will make sense in no time! Take a look at the below complex sentences from literature:

  •  As Grainier drove along in the wagon behind a wide, slow, sand-colored mare, clusters of orange butterflies exploded off the blackish purple piles of bear sign and winked and fluttered magically like leaves without trees. – Train Dreams, Denis Johnson
  •  Because he was so small, Stuart was often hard to find around the house. – Stuart Little, E.B. White
  •  The Scarecrow and the Tin Woodman stood up in a corner and kept quiet all night, although of course they could not sleep. – The Wonderful Wizard of Oz, L. Frank Baum
  •  Because he was so small, Stuart was often hard to find around the house – E.B White,  Stuart Little
  • I’ve never any pity for conceited people, because I think they carry their comfort about with them. – George Eliot, The Mill on the Floss
  •  Many years later, as he faced the firing squad, Colonel Aurelian Buendia was to remember that distant afternoon when his father took him to discover ice. – One Hundred Years of Solitude, Gabriel Garcia Marquez
  •  If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. – Walden, Henry David Thoreau
