Key Rules

1. Context determines register

Always consider context before choosing vocabulary.

Examples:
  • Academic → Formal
  • Business → Neutral–formal

  • Technical → Neutral

2. Audience shapes word choice

Adapt vocabulary to your readers.

Examples:
  • Experts → Technical terms
  • General audience → Accessible wording
  • Academic readers → Formal register
  • Friends → Informal register

3. Consistency matters

Maintain one dominant register unless you have a reason to change.

Examples:

  • Stay consistent within sections
  • Change register only when needed
  • Explain or signal major shifts
