Choose a boundary that expresses the link

1 · Learn

A semicolon can join closely related independent clauses: 'The rain stopped; the match resumed.' Each side could stand as a sentence. A colon can introduce an explanation: 'We had one problem: the key was missing.'

A dash can mark a strong break or added explanation. These marks are choices for meaning, not replacements for every comma. Check clause structure before inserting them.

Key words and supplied examples.

2 · Worked example

I use a semicolon in 'The door was locked; nobody could enter' because both clauses stand independently and are closely linked.

3 · Your turn

Join 'The model looked sturdy. Its joints were loose.' with a semicolon. Explain why it is possible.

Check your answer

'The model looked sturdy; its joints were loose.' Each part is an independent clause, and the second contrasts with the first.

4 · Apply your learning

Write an explanatory colon sentence and a semicolon sentence, then test both sides aloud.

Adult guidance and safety

Read the supplied text together if needed. Accept well-supported alternative interpretations, not invented evidence. Use wider whole books, poems and plays alongside these short original models; provide specific feedback on writing and revisit spelling over time.
