Confused About Using Semicolons When Combining Two Sentences
Hi everyone, I'm having trouble figuring out when it's appropriate to use a semicolon instead of a comma, especially when I'm joining two related sentences. For example, I wrote: "She finished her homework; then she watched TV." But I'm not sure if that's correct, or if I should use a comma or just start a new sentence.
I've also seen examples like: "I went to the store, I bought some apples." Is that a situation where a semicolon is needed? I'd really appreciate any clarification or rules you use to decide when a semicolon makes sense.
Context:
I'm preparing for an academic English exam and want to improve my punctuation skills.

A helpful pattern to remember is: use a semicolon to join two independent clauses (complete sentences) that are closely related, without a coordinating conjunction (such as 'and', 'but', 'or').
Pattern:
- Independent sentence ; independent sentence.
Examples:
- "The meeting ended; everyone left quickly."
(Correct: both sides can stand alone, and are closely related in thought) - "The meeting ended, everyone left quickly."
(Incorrect: comma splice—two sentences joined by only a comma)
Self-check:
Try splitting your sentence at the punctuation mark. If each part makes sense on its own, and the ideas are linked, a semicolon is probably correct.
Practice:
Write two related sentences that could each stand alone. Join them with a semicolon. Now, try the same with a comma—a comma should feel wrong if you're joining complete sentences that way.
When reviewing your work, look for places where you have two complete sentences joined by just a comma; this mistake is called a comma splice and is often fixed by replacing the comma with a semicolon. For example:
- "The sun set, the streetlights turned on." (Incorrect: comma splice)
- "The sun set; the streetlights turned on." (Correct: two related complete sentences, joined by semicolon)
Tip: If you find a comma between two full sentences, try reading each side separately. If both are complete thoughts but you don't use 'and' or another conjunction, a semicolon is correct.
Quick Practice:
Take a draft of your writing and highlight every comma. For each, ask: Is this joining two independent sentences without a conjunction? If yes, switch to a semicolon.
To decide whether to use a semicolon or a comma, compare sentences with connectors versus those without. Use a semicolon when linking two complete, related sentences without a conjunction; use a comma when a coordinating conjunction (for, and, nor, but, or, yet, so) is present.
Example A:
- "He packed his suitcase; he called for a taxi."
- "He packed his suitcase, and he called for a taxi."
The first sentence uses a semicolon because there is no conjunction. The second is correct with a comma because of 'and.' Using only a comma: "He packed his suitcase, he called for a taxi." is incorrect (comma splice).
Practice:
Write a pair of related sentences. Combine them once with a semicolon and once with a comma + conjunction. Notice how the meaning changes (or stays the same), and check that both parts are complete sentences.
