Sentence combining for flow
Writing that uses too many short sentences in a row can feel choppy and hard to read. Combining sentences creates smoother flow and shows how ideas connect. Three tools do this well: conjunctions, adverbials and relative clauses — each joining ideas in a different way without creating a run-on.
- How to combine short sentences using conjunctions, adverbials and relative clauses
- How each combining method creates a different kind of connection between ideas
- How to avoid run-on sentences when combining
- Conjunction — a joining word that connects two clauses. Coordinating conjunctions (and, but, so) join equal ideas; subordinating conjunctions (because, when, although) show how one idea depends on another.
- Adverbial — a word or phrase that shows when, where or how. Moving it to the front of a combined sentence helps ideas flow. For example, After the game, they shook hands.
- Relative clause — a group of words beginning with who, which or that, used to add information about a noun inside the sentence. For example, The student who raised her hand knew the answer.
- Run-on — two complete sentences joined without any punctuation or conjunction. For example, She was tired she went to bed is a run-on and must be fixed.
How it works
1Combining with conjunctions
Conjunctions are the most direct way to combine two short sentences. Choosing the right conjunction shows the relationship between the ideas.
- Coordinating conjunctions (and, but, so, or) join two ideas of equal weight. For example, She was tired. She went to bed. becomes She was tired, so she went to bed.
- Subordinating conjunctions (because, when, although, after) show that one idea depends on the other. For example, He paused. He chose calm words. becomes He paused before he chose his words.
- Comma with coordinating conjunctions — when joining two complete clauses with and, but or so, add a comma before the conjunction.
2Combining with an adverbial starter
An adverbial can move to the front of a combined sentence to show when or how something happened. This reduces choppy repetition and creates a smoother opening.
- Move the time or manner idea first — take the idea that tells when or how and place it at the start, followed by a comma. For example, After the bell rang, the students lined up.
- Comma after the starter — a comma always follows a fronted adverbial before the main clause begins.
3Combining with a relative clause
A relative clause adds information about a noun without starting a new sentence. This reduces repetition when two sentences refer to the same person or thing.
- Who is used for people. For example, Liam paused. He was feeling frustrated. becomes Liam, who was feeling frustrated, paused.
- Which is used for things. For example, The note was on the desk. It helped everyone. becomes The note, which was on the desk, helped everyone.
- Commas around the clause — when a relative clause adds optional extra information, commas wrap around it.
See it in action
Two choppy sentences combined with a conjunction
She was upset. She stayed calm.
She was upset, but she stayed calm.
Adding but and a comma joins the two ideas and shows the contrast between them clearly.
Adverbial moved to the front to improve flow
He took a breath. He answered the question after that.
After taking a breath, he answered the question.
Moving the time idea to the front removes repetition and creates a smoother, more natural sentence.
Relative clause added to reduce repetition
Maya raised her hand. Maya knew the answer.
Maya, who knew the answer, raised her hand.
The relative clause adds the second idea inside the first sentence, avoiding the repeated use of Maya.
- Conjunctions join two clauses and show how ideas are related — use a comma before coordinating conjunctions.
- Adverbials at the front of a sentence show when or how, and are always followed by a comma.
- Relative clauses add information about a noun using who, which or that.
- A run-on is two complete sentences joined with no punctuation or conjunction — always fix these.
- Mixing combining methods creates writing with better rhythm and flow.
- conjunction(n.) a word that joins clauses or ideas — and, but, so and because are conjunctions used to combine sentences.
- run-on(n.) an error where two complete sentences are joined without a conjunction or punctuation — She was tired she went to bed is a run-on.
- relative clause(n.) a clause beginning with who, which or that that adds information about a noun — in The student who answered was correct, the relative clause is who answered.
