Styles of Communication: Formal, Informal, and Semi-Formal
Communication style refers to the tone, language, structure, and approach a speaker or writer
uses to convey a message. Choosing the right style depends on the context, audience, and
purpose of communication. Let’s explore the three main styles:
1. Formal Communication Style
Formal communication is structured, respectful, and used in professional or serious settings. It
follows standardized grammar, vocabulary, and etiquette.

o Often uses passive voice and technical or academic vocabulary
• Examples:
o Business reports, job applications, official speeches, academic writing
o “I am writing to inform you about the upcoming policy changes.”
• Purpose:
o To convey authority, professionalism, and clarity
o To maintain respect and credibility
• When to Use:
o In professional emails, official documents, presentations, interviews, legal or
academic contexts
2. Informal Communication Style
Informal communication is casual, friendly, and spontaneous. It’s commonly used among
friends, family, or in relaxed settings.
• Features:

3. Semi-Formal Communication Style
Semi-formal communication strikes a balance between formal and informal styles. It’s polite
and respectful but allows some degree of friendliness and ease.

interactions, speeches to mixed audiences

customers, or writing to a known audience in a workplace
