Grade 9 · Style and Syntax · Syntax for Effect
Parallelism and Sentence Variety
Use parallel structure, varied sentence length and semicolons and colons to control emphasis.
Learning objectives
- Correct faulty parallelism
- Vary sentence openings and lengths deliberately
- Use colons and semicolons accurately
Common Core ELA alignment
L.9-10.1
Demonstrate command of the conventions of standard English grammar and usage when writing or speaking. Grades 9–10 emphasis: sustain a line of analysis across complex texts, using precise evidence and a formal academic register.
L.9-10.2
Demonstrate command of the conventions of standard English capitalization, punctuation and spelling when writing. Grades 9–10 emphasis: sustain a line of analysis across complex texts, using precise evidence and a formal academic register.
L.9-10.3
Use knowledge of language and its conventions when writing, speaking, reading or listening, choosing precise and concise wording. Grades 9–10 emphasis: sustain a line of analysis across complex texts, using precise evidence and a formal academic register.
MYP criteria
- Criterion D — Using language
ENGAGE
Hear the wobble
She likes running, to swim, and cycling. Something is wrong, and it is not the meaning. The three items are not in the same grammatical form.
Think about it
- Fix the sentence three different ways.
- Why does the original feel unbalanced?
EXPLAIN
Three levers of style
1. Parallelism
- Items in a list must share a form: running, swimming, cycling.
- Paired conjunctions must frame equal structures: not only cheaper but also faster.
- Parallelism creates rhythm and makes complex ideas readable.
2. Sentence variety
| Opening | Example | Effect |
|---|---|---|
| Subject first | The committee rejected the plan. | Neutral, direct |
| Subordinate clause first | Although funds existed, the committee rejected the plan. | Sets condition before outcome |
| Participle first | Facing an election, the committee rejected the plan. | Adds motive economically |
| Short sentence after long | ...for eleven months. Then it collapsed. | Emphasis by contrast |
3. Colons and semicolons
- Colon: announces what follows, such as a list, explanation or quotation.
- Semicolon: joins two closely related independent clauses, or separates complex list items.
- Neither should be used where a full stop already works better.
Revision habit
Read your paragraph aloud and mark sentence lengths. Three sentences of similar length in a row is a signal to vary one.
EXPLORE
Revise for style
The proposal was expensive. The proposal was slow. The proposal was unpopular with staff. The committee rejected it. They rejected it because of the cost and it was slow and staff did not like it.
Think about it
- Combine these into two sentences using parallelism and a colon or semicolon.
- Which version emphasises cost most strongly, and why?
MYP_PRACTICE
Criterion D task
Take 150 words of your own recent writing. Revise it to include one parallel list, one sentence opening with a subordinate clause, one short emphatic sentence and one correct semicolon. Annotate each change.
EXIT_TICKET
Check yourself
Think about it
- Write one sentence with correct parallelism.
- When would you choose a colon over a semicolon?
