Error: comma splice. A comma alone isn’t strong enough to connect two sentences.

-
Note: The semicolon is correct! The only issue is the capital T in “This.” It’s a minor error, but usually the word after a semicolon should not be capitalized unless it’s a proper noun.

Try It Yourself
Combine each pair with a semicolon:
-
The sky grew dark. The stars began to appear.
-
I forgot my homework. My teacher was not pleased.
-
Our team practiced hard. We wanted to win the game.
(Check yourself: each result should be two complete sentences joined by a semicolon.)
Semicolons + Transition Words
Sometimes you want to link two complete sentences with a transition word (like however, therefore, for example, in fact). A comma isn’t enough — you need a semicolon before the transition word and a comma after it.
Formula:
Sentence A ; transition word, sentence B.
Examples:
-
✅ They bring together people of different backgrounds and remind them of shared goals; therefore, this can foster a sense of pride and unity.
-
✅ The concert was canceled; however, the tickets will be refunded.
-
✅ She studied hard; in fact, she reviewed every night for a week.
Common Mistakes:
-
❌ They bring together people … , therefore this can foster … (comma splice: comma isn’t strong enough).
-
❌ They bring together people … ; therefore this can foster … (missing comma after therefore).
Practice
Combine each pair of sentences using a semicolon + transition word (you pick the right one).
-
We planned a picnic. It started to rain. (use “however”)
-
He didn’t prepare for the test. He still passed. (use “in fact”)
-
