✍️ The Comma That Costs Marks

You wrote a brilliant sentence. Then you wrote another one. You separated them with a comma. AQA just knocked a mark off for AO6.

A comma splice is one of the most common errors in GCSE writing — and one of the cheapest to fix. Two complete sentences joined only by a comma is not a stylistic choice: it is a boundary violation. Three letters and a capital can repair it.

What is a comma splice?
<strong>A comma splice</strong> is when two complete sentences (independent clauses) are joined with only a comma &mdash; which is not strong enough to hold them together.<br><br><strong>Error:</strong> &ldquo;She laughed, it was the funniest thing she&rsquo;d ever seen.&rdquo;<br><strong>Fixed:</strong> &ldquo;She laughed. It was the funniest thing she&rsquo;d ever seen.&rdquo;<br><br><strong>Test:</strong> can each side stand alone as a sentence? If yes &mdash; a comma alone is not enough.
What are the three ways to fix a comma splice?
<strong>1. Full stop + capital letter</strong> &mdash; simplest; equal weight on each idea.<br><em>&ldquo;It rained all day<strong>. Nobody</strong> came.&rdquo;</em><br><br><strong>2. Semicolon</strong> &mdash; keeps clauses close; use when they are tightly linked.<br><em>&ldquo;It rained all day<strong>; nobody</strong> came.&rdquo;</em><br><br><strong>3. Conjunction</strong> (but, so, and, yet) &mdash; shows the logical relationship.<br><em>&ldquo;It rained all day<strong>, so nobody</strong> came.&rdquo;</em><br><br><em>Tip: &ldquo;so&rdquo; = result; &ldquo;but / yet&rdquo; = contrast; &ldquo;and&rdquo; = addition.</em>
