- A colon introduces a list, explanation, example, or quotation
- A semicolon joins two closely related complete sentences
- Both marks are stronger than a comma, but they do different jobs
Section 1What a colon does
A colon points forward to something coming next. Use it before a list, example, explanation, or quotation. The thing to remember is: a colon says 'here it comes'.
Section 2What a semicolon does
A semicolon joins two complete sentences that are closely connected. It is stronger than a comma but not as final as a full stop. Example: 'The rain started; the match was postponed.'
Section 3The complete-sentence test
For a semicolon, both sides should usually be complete sentences. 'I packed three things; books, pens, and lunch' is wrong because the second part is not a full sentence. Use a colon there instead.
Section 4Exam writing
These marks can make writing sharper, but only when used carefully. Watch out: do not sprinkle semicolons everywhere to sound fancy. Clear punctuation beats decoration every time.
Examples
Choose the correct punctuation: 'Bring three items __ pen, ruler, and calculator.'
Use a colon: 'Bring three items: pen, ruler, and calculator.' The colon introduces the list.
Correct this: 'The bus was late, I missed assembly at Ardenne.'
Use a semicolon or full stop: 'The bus was late; I missed assembly at Ardenne.' Both sides are complete and closely related.
