How to Use Semicolons and Colons — Answers
Part A: Which mark?
A semicolon links two main clauses that are closely related, or separates items in a complex list. A colon comes after a complete clause and introduces a list, an explanation or an example. Circle the mark that fits each gap.
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: semicolon ( ; )
Two closely related main clauses, each of which could stand alone, can be joined with a semicolon. A comma alone would create a comma splice.
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: colon ( : )
A colon introduces a list after a complete clause (You will need three things for the hike).
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: colon ( : )
A colon can introduce an explanation of what came before. The second part explains the flaw.
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: semicolon ( ; )
Use a semicolon before a linking adverb such as however, therefore or meanwhile when it joins two main clauses, and a comma after it.
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: semicolon ( ; )
When list items already contain commas, semicolons separate the items so the reader does not get lost.
- Asemicolon ( ; )
- Bcolon ( : )
- Ccomma ( , )
Answer: comma ( , )
With a joining word such as and, but or so, use a comma (or nothing in a short sentence), not a semicolon.
Part B: Right or wrong?
Circle True or False.
Answer: False
The words before the colon (The subjects I enjoy most are) are not a complete clause. Remove the colon, or rewrite: I enjoy three subjects most: art, science and music.
Answer: True
Both parts are main clauses, and they are closely related (the second explains the first).
Answer: False
Because it was late is a subordinate clause and cannot stand alone. Use a comma: Because it was late, we went home.
Part C: Punctuate it
Rewrite each sentence with the punctuation asked for.
Answer: The museum was closed; we went to the park instead.
Answer: The road was flooded; therefore, the school buses could not run.
Answer: The recipe needs only four ingredients: flour, eggs, milk and butter.
Answer: Ava finally understood why the plant had died: nobody had watered it for a month.
Answer: The finalists were Leo, the drummer; Aisha, the singer; and Ben, the pianist. (Without semicolons, a reader might think there were six finalists.)
Part D: Your turn
Model answer: 1. The race started at dawn; the air was still cold and misty. 2. I had trained for months; however, my legs felt heavy from the first step. 3. At the drink station I grabbed three things: a cup of water, a slice of orange and a handful of jelly beans. 4. In the end I learned an important lesson: start slowly and finish strongly.
Success criteria:
- Semicolon correctly joins two related main clauses
- Semicolon before however or therefore, with a comma after it
- Colon introduces a list after a complete clause
- Colon introduces an explanation after a complete clause
- All four sentences are complete and make sense
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
