Here, independent means main, and dependent means subordinate. An independent clause can stand alone: 'The torch glowed.' A dependent clause cannot stand alone as a complete sentence: 'Although the torch flickered' needs a main clause. Find the subjects and verbs, then test which clauses can stand alone. A simple sentence has one independent clause and no dependent clauses. Several verbs can share its subject: 'Noor and Ben packed bags and checked the map.' This is still simple. A compound sentence has at least two independent clauses and no dependent clauses. Join them with a comma and a coordinating conjunction such as and, but or so, or with a semicolon. A comma alone cannot join two independent clauses correctly. *(drawing: Each clause can stand alone. A comma and 'and' join them into a compound sentence.)* **Example.** A compound sentence can have more than two clauses: 'The kettle whistled, the toast popped, and Dad poured tea.' Test each part: 'The kettle whistled', 'the toast popped' and 'Dad poured tea' can each stand alone. That gives three independent clauses. In this series, commas separate the clauses, and 'and' introduces the last one. A complex sentence has one independent clause and at least one dependent clause. To build one, add because for cause, when or after for time, or although for contrast before a clause. Attach it to a main clause. Put a comma after an opening dependent clause. Dependent clauses can also follow the main clause. While can show two events happening together. A sentence can have more than one dependent clause: 'Before we left, I waited while Noor tied her boots.' A compound-complex sentence has at least two independent clauses and at least one dependent clause. In 'The crew waved while the ferry docked, and we walked aboard', 'The crew waved' and 'we walked aboard' are independent. 'While the ferry docked' is dependent, even in the middle. Count clauses instead of using sentence length. Relative clauses, which describe nouns, also count as dependent clauses. Sentence type and length are different choices. Repeated short sentences can sound choppy, while repeated long ones can tire a reader. A short simple sentence after longer ones can add emphasis or tension. To revise, combine some ideas into a complex sentence and leave another simple, or split a long sentence. Keep every event, its timing and any stated cause or contrast. Choose joining words for the meaning you want. **Example.** Combine two simultaneous events with as or while: 'While Jo danced, I clapped. Ben sang at the same time.' 'While Jo danced' cannot stand alone, so it is dependent. 'I clapped' is independent. One independent clause with a dependent clause makes the first sentence complex. Use a comma after an opening dependent clause. 'Ben sang at the same time' has one independent clause and no dependent clauses, so it is simple. Keep every event and its timing. **Example.** Keep contrast with but and cause with so: 'Ice formed, but we skated. The sun warmed us, so we smiled.' Each has two independent clauses that can stand alone and no dependent clauses, so each is compound. Split 'When music stopped, we bowed' into 'Music stopped. We bowed then.' Each new sentence has one independent clause and no dependent clauses, so each is simple. Then preserves when we bowed. Keep every event and relationship. **Recap.** Simple, compound, complex, and compound-complex sentences combine clauses in different patterns, so choose the pattern that fits the relationship you want to show. *Original sentence-structure lesson, revision examples, questions and flashcards written for this dataset.* ## Practice 24 questions on this page, each with its working shown. ## Needs first - [Fixing Fragments & Run-Ons](https://lightmysky.com/learn/english/fixing-fragments-and-run-ons-mt_7oZ2YenzhX) - [Phrases & Clauses](https://lightmysky.com/learn/english/phrases-and-clauses-mt_IdFxLz-UW9) - [Relative Clauses](https://lightmysky.com/learn/english/relative-clauses-mt_YQ64pzcLDl) ## Optional connections - [Correlative Conjunctions](https://lightmysky.com/learn/english/correlative-conjunctions-mt_S7CnyZCnxg) ## Opens up - [Grammar for Effect](https://lightmysky.com/learn/english/grammar-for-effect-mt_N5tiL3uIeq) - [Joining Ideas: Clauses in Another Language](https://lightmysky.com/learn/languages/joining-ideas-clauses-in-another-language-mt_Vf6M9DJmW7)
