Run-On Sentences


What is a Run-On Sentence?

​​​

A run-on sentence packs two or more complete thoughts into a single sentence, lacking proper punctuation or connecting words. This grammatical error confuses readers by crowding ideas and making it difficult to follow the writer's message.

 

Types of Run-On Sentences

  • Fused Sentence: Two sentences joined with no punctuation. To illustrate the confusion, consider this example before correction: 'Ravi finished his homework and he went out to play cricket.' Notice how the absence of a period leads to ambiguity. Now, see the improved clarity with punctuation: 'Ravi finished his homework. He went out to play cricket.'

  • Comma Splice: If you join sentences using just a comma, you’re making a comma splice. For instance, consider the sentence: 'I went to the market, I forgot to buy turmeric.' This incorrect structure joins two independent thoughts with just a comma. I went to the market, but I forgot to buy turmeric.

  • Polysyndeton: This involves using many conjunctions in a row without commas or periods. Tons of conjunctions, but no commas or periods.

    The rain started, and the power went out, and everyone waited, and the mango seller laughed

Each type confuses, leaving readers unsure where one idea ends and another begins, thereby disrupting comprehension.

Run-On Sentence examples in daily life

  • The auto is late; my meeting starts at ten.

  • She brought sweets, and the guests arrived early. Everyone rushed to the counter, and the tickets sold out fast.

  • I enjoy biryani; he prefers dose. Meera went to the store, and she got soaked in the rain.

Notice how these run-on sentences cram multiple complete thoughts together, usually without the right punctuation or connecting words. In our modern communication landscape, run-ons also sneak into workplace emails. For example, 'I completed the report and sent it to the team. They should review it by tomorrow.' Consider social media posts as well: 'Just finished my workout and I feel amazing, what a great start to the day!' By recognizing these instances, whether in professional settings or casual chats, you can enhance clarity across all your writing platforms.

How to Fix Run-On Sentences

  • Add a Full Stop: The auto is late. My meeting starts at ten.

  • Use a Comma and a Coordinating Conjunction (words like "and," "but," "or," which join equal ideas): She brought sweets, and the guests arrived early.

  • Add a Semicolon: Everyone rushed to the counter; tickets sold out fast.

  • Split Into Separate Sentences: I enjoy biryani. He prefers dosa.

  • Use Subordination (start the sentence with a subordinating conjunction, such as "when," "because," or "although," to make one idea depend on the other): When Meera went to the store, she got soaked in the rain.

To avoid run-on sentences, check for complete thoughts, and use punctuation or joining words to separate them.

Run-On Sentence Rules

  • Each complete thought (independent clause) needs clear punctuation: a full stop, a comma with a conjunction, or a semicolon. Don’t use a comma alone to join your two sentences—it creates a comma splice.

  • Don’t pile conjunctions into your sentences without breaking them up.

To help you monitor your drafts for these rule points, try using a simple checklist. This step-by-step guide will offer a practical tool for self-editing. For each sentence, go through the following steps:

  • Check for complete thoughts and ensure they are punctuated correctly with full stops, semicolons, or commas followed by coordinating conjunctions.

  • Look for any instances where a comma is used without a coordinating conjunction, and make necessary corrections to prevent comma splices.

  • Analyze the use of conjunctions. Ensure they are not overused, which can result in unnecessarily long and confusing sentences.

By consistently applying this checklist to each sentence, you can significantly improve the accuracy and clarity of your writing over time.

Sentence fragments are incomplete ideas, while run-on sentences pack too much together without clarity. Both disrupt the flow. Fixing both problems ensures smoother, more professional writing. For example, consider a repaired fragment versus a repaired run-on:

Repaired fragment: Because the rain started, we grabbed umbrellas.

Repaired run-on: Everyone waited for the rain to stop; meanwhile, we decided to head out.

Placing these examples side by side helps crystallize the distinct fixes required for each issue.

Why fixing Run-Ons matters

Run-on sentences make your writing messy and hard to read. This is especially true in formal contexts. Readers can lose track of the message. Listen for natural pauses and add punctuation where you’d normally take a breath.
