Principle Reference

• Choose a suitable design and stick to it — Plan your structure. Know whether you're building a tent or a cathedral. The design may change, but have one.

• Make the paragraph the unit of composition — Each paragraph should develop one topic. Begin with a topic sentence; end with emphasis. Don't chop into single sentences or let paragraphs run too long.

• Use the active voice — "The active voice is usually more direct and vigorous than the passive." Write "I shall always remember my first visit" not "My first visit will always be remembered by me."

• Put statements in positive form — Say what is, not what isn't. "He usually came late" is stronger than "He was not very often on time." Avoid not un- constructions.

• Use definite, specific, concrete language — Prefer the specific to the general, the definite to the vague, the concrete to the abstract. "A period of unfavorable weather set in" → "It rained every day for a week."

• Omit needless words — "Vigorous writing is concise." Every word should tell. Common offenders:
• "the question as to whether" → "whether"
• "there is no doubt but that" → "no doubt" / "doubtless"
• "the fact that" → often deletable
• "who is" / "which was" → often deletable

• Avoid a succession of loose sentences — Don't string together clauses with "and," "but," "so." Vary sentence structure. Use subordination.

• Express coordinate ideas in parallel form — Similar content deserves similar form. "The French, the Italians, Spanish, and Portuguese" → "The French, the Italians, the Spanish, and the Portuguese."

• Keep related words together — Place modifiers near what they modify. "He only found two mistakes" → "He found only two mistakes."

10. In summaries, keep to one tense — When summarizing a work, use present tense throughout. Don't shift between present and past.

11. Place the emphatic words at the end — The end of a sentence is its most prominent position. Build toward the key word. "Humanity has hardly advanced in fortitude since that time, though it has advanced in many other ways" → weak ending. Revise for emphasis.

Summary

Overall Structure: [Well-organized/Needs Work/Disorganized]

Top 3 Improvements:

• [Most impactful structural change]
• [Second priority]
• [Third priority]

Guidelines

• Focus on patterns rather than isolated instances
• Active voice isn't always better—passive is appropriate when the actor is unknown or unimportant
• "Omit needless words" doesn't mean "omit all words"—rhythm and clarity sometimes need extra words
• Technical writing may legitimately need longer explanations
