What type of language should academic essays avoid?

Academic essays are designed to convey ideas clearly and effectively, requiring a level of professionalism and formality in language use. Casual language, characterized by its informal tone, colloquial expressions, and everyday terms, can undermine the scholarly nature of an essay. This type of language may lead to ambiguity or a lack of precision, which is crucial in academic writing where clarity and a formal tone are essential for the reader's understanding.

By avoiding casual language, academic writers are better equipped to present their arguments, analyses, and findings with appropriate seriousness and respect for the subject matter. This helps ensure that the essay meets the standards expected in an academic context and communicates the ideas to the audience effectively.
