Formal Writing vs. Informal Writing: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on October 13, 2023
Formal writing adheres to traditional conventions and is impersonal, while informal writing has a relaxed, personal style and may include colloquial expressions.

Key Differences

Formal writing is characterized by its adherence to standard grammatical structures and often exhibits a professional or academic tone. The language employed in formal writing is typically more complex and intricate, adhering strictly to grammatical and syntactical rules. In contrast, informal writing tends to be more conversational and may involve the use of slang or colloquial expressions.
In the realm of formal writing, pronouns such as “one” may be used to maintain a sense of impersonality, avoiding the direct reference to self or others. Informal writing might freely use pronouns like “I”, “you”, and “we”, nurturing a direct and personal connection between the writer and reader. Formal writing maintains a distance, employing an objective and neutral tone throughout.
Formal writing often utilizes longer sentences and a sophisticated vocabulary to convey its message with precision and clarity. On the flip side, informal writing may employ shorter sentences and a simpler vocabulary to create an easy, relatable, and digestible narrative. Formal writing tends to avoid contractions (such as can’t, won’t), while informal writing may embrace them for a smoother, conversational flow.
Specific contexts call for formal writing, such as academic essays, official reports, and business correspondence. Whereas, informal writing often finds its place in personal letters, blogs, and social media posts. Thus, formal writing and informal writing are not merely about language choices, but also the appropriateness and effectiveness of communication in various scenarios.
Despite their differences, both formal writing and informal writing serve crucial roles in diverse communicative contexts. Striking a balance and knowing when to employ either style enhances the writer’s ability to convey messages effectively to varied audiences.
