  • Complex Sentence Structures: Formal writing often contains long, complex sentences with sophisticated vocabulary.
  • Objective Tone: The tone is impersonal and objective, avoiding emotions and personal opinions.
  • Full Grammatical Structures: Formal language employs complete grammatical structures, including full noun and verb phrases.

Examples of formal register usage include academic papers, business correspondence, and official speeches. To learn more about the characteristics of formal and informal language, you can visit the Cambridge Dictionary.
