Colons, semicolons & hyphens

Answers and reasoning. Review before teaching.

1. Which punctuation mark correctly introduces a list after a complete main clause: “Please pack the following three items____ a compass, a notebook and a water bottle” (a colon : or a semicolon ;)?
Colon (:)
A colon follows a complete independent clause to introduce a list or explanation.
2. Choose the punctuation mark that links these two contrasting independent clauses: “Some planets have rocky surfaces____ others are giant spheres of gas” (Semicolon ; or Apostrophe ’).
Semicolon (;)
A semicolon balances two parallel or contrasting independent clauses.
3. When list items themselves contain internal commas, which punctuation mark should separate the items: “We visited Male, Maldives____ Colombo, Sri Lanka____ and Kochi, India” (semicolons ; or commas ,)?
Semicolons (;)
Semicolons act as “super-commas” to separate complex list items that already contain commas.
4. Which sentence uses the colon correctly: “Remember the carpenter’s rule: measure twice and cut once.” or “Remember: to measure twice and cut once.”?
Remember the carpenter’s rule: measure twice and cut once.
“Remember the carpenter’s rule” is a complete clause that sets up the appositive rule after the colon.
5. What punctuation mark indicates a trailing-off thought or omitted words in a quotation (. . .): an ellipsis or a colon?
Ellipsis
An ellipsis (...) shows an omission in quoted text or a pause/trailing thought.
6. Which prefix almost always requires a hyphen when attached to a noun, as in “self-confidence” and “self-reliant”: self- or un-?
self-
Compounds formed with the prefix “self-” are hyphenated in standard English.
7. Which punctuation pair encloses a quiet clarification, date range or acronym definition such as “World Health Organization (WHO)”: parentheses / round brackets ( ) or semicolons ;?
Parentheses / round brackets ( )
Parentheses enclose supplementary dates, acronyms and non-essential clarifications.
8. In “a ten-minute walk”, why is “ten-minute” hyphenated and singular: it acts as a unit modifier before the noun “walk”, or it is a plural verb?
It acts as a unit modifier before the noun “walk”
Measurement phrases before a noun (“a ten-minute walk”, “a five-kilometre run”) are hyphenated in singular form.
9. Which punctuation mark correctly links two closely related independent clauses without a conjunction: “The tide had turned____ the lagoon was now deep enough for the boat” (a semicolon ; or a comma ,)?
Semicolon (;)
A semicolon joins two closely related independent clauses; using only a comma creates a comma splice.
10. In “twenty-three”, what punctuation mark joins the tens word and the ones word: a hyphen (-) or an apostrophe (’)?
Hyphen (-)
A hyphen connects compound numerals from 21 to 99.
11. Why does “a slowly moving cloud” NOT take a hyphen after “slowly”: adverbs ending in “-ly” are not hyphenated before participles or adjectives, or adverbs are nouns?
Adverbs ending in “-ly” are not hyphenated before participles or adjectives
Because “-ly” already signals that the word modifies the following participle, no hyphen is used.
12. Is a colon correct directly after a verb in “The three primary colours of light are: red, green and blue” (Yes or No)?
No
Do not place a colon directly between a verb or preposition and its objects; a colon should follow a complete clause.
