Apply William Strunk Jr.'s principles from The Elements of Style to improve any piece of prose. This skill enforces clarity, concision, and vigor through specific, actionable rules.
For reports, research write-ups, guidance, documentation and summaries, use references/report-writing-style.md.
Good writing is clear, concise, and vigorous. Every rule exists to serve the reader. Strunk's core tenets:
The mature writer knows the rules well enough to break them with purpose and payoff.
Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences.
| Bloated | Concise |
|---|---|
| the question as to whether | whether |
| there is no doubt but that | no doubt / doubtless |
| used for fuel purposes | used for fuel |
| he is a man who | he |
| in a hasty manner | hastily |
| owing to the fact that | since / because |
| in spite of the fact that | though / although |
Avoid: "the fact that" in all its forms. Replace with direct nouns or verbs:
Cut redundant words: If a word adds no meaning, remove it.
The active voice is usually more direct, vigorous, and concise than the passive.
When passive is appropriate:
Avoid double passives:
Avoid weak existentials:
Make definite assertions. Avoid tame, colorless, hesitating language. Tell the reader what is, not just what is not.
| Negative | Positive |
|---|---|
| not honest | dishonest |
| not important | trifling |
| did not remember | forgot |
| did not pay attention to | ignored |
| He was not very often on time | He usually came late |
When negation works:
Word position is the principal means of showing relationship.
Subject and verb: Do not separate with a phrase that can be transferred to the beginning
Relative pronouns: Should immediately follow their antecedents
Modifiers: Must come next to the word they modify
Parallel construction requires that expressions of similar content and function be outwardly similar.
Correlative expressions (both...and, not...but, not only...but also) must be followed by the same grammatical construction:
The most prominent position in a sentence is the end. Place the logical predicate — the new element — there.
Any element other than the subject becomes emphatic when placed first:
One paragraph per topic. The paragraph break signals to readers that "a new step in the development of the subject has been reached."
Ideal paragraph structure:
Exceptions:
Enclose interruptions between pairs of commas. You may omit both if the interruption is slight, but never omit one and leave the other.
Non-restrictive (adds supplementary info): set off by commas. Can be split into two sentences.
Restrictive (limits the noun): no commas. Cannot be split into two sentences.
Place a comma before and or but introducing an independent clause:
Deeper advice: These "loose" sentences often feel like after-thoughts. Recast with subordination:
Do not join independent clauses by a comma alone. Use a semicolon or period:
Adverbs are not conjunctions: If the second clause is introduced by accordingly, besides, so, then, therefore, or thus, the semicolon is still required.
Do not use a period where a comma belongs:
A participial phrase at the beginning of a sentence must refer to the grammatical subject:
Words drained of meaning through overuse signal lazy writing:
Replace vague, roundabout expressions with concrete, specific sentences:
A misspelled word signals inattention, and inattention in mechanics suggests inattention in thought.
| Word | Common Error |
|---|---|
| advice (noun) / advise (verb) | advise used as noun |
| affect (verb) / effect (noun) | Interchanged |
| led (past tense) / lead (present) | lead used as past tense |
| lose (verb) / loose (adjective) | loose used as verb |
| principal (main) / principle (truth) | Interchanged |
Always add 's to form the possessive singular, regardless of final consonant:
Pronominal possessives take no apostrophe: hers, its, theirs, yours, oneself
In a series of three or more terms, place a comma after each term except the last:
Evaluate any piece of writing against these criteria:
The best writers sometimes disregard the rules of rhetoric. When they do so, the reader will find in the sentence some compensating merit, attained at the cost of the violation.
Rule-breaking requires payment. Every rhetorical violation must be purchased with "some compensating merit." The violation is never free. The reader should sense that the departure from convention was deliberate and earned.
The learning sequence:
| Mistake | Why It Fails | Fix |
|---|---|---|
| "The question as to whether" | Wordy, indirect | "whether" |
| "There were a great number of..." | Weak existential, wordy | Direct subject + verb |
| "He is a man who is very ambitious." | Redundant construction | "He is very ambitious." |
| "I met them. Coming home from New York." | Sentence fragment | "I met them, coming home from New York." |
| "Walking down the road, the house was seen." | Dangling modifier | "Walking down the road, he saw the house." |
| "The ceremony was both long and very tedious." | Faulty parallelism | "The ceremony was both long and tedious." |
| "My opinion is as good or better than his." | Incomplete comparison | "My opinion is as good as his, or better." |
| "However, we at last succeeded." | Misplaced however | "At last, however, we succeeded." |
| "A literal flood of abuse" | Misused literal | "A flood of abuse" |
| "Most everybody" | Colloquialism | "Almost everybody" |
