In academic writing, when is it important to avoid colloquial expressions?

In academic writing, it is crucial to avoid colloquial expressions because they often reduce word precision and clarity. Academic writing relies on a formal tone that conveys ideas in a clear and precise manner. Colloquial expressions, which are informal and conversational, can introduce ambiguity and may not be universally understood within a diverse readership. This lack of clarity can hinder effective communication of research findings, arguments, or theoretical discussions, which are fundamental in scholarly work. Maintaining precision in language ensures that the intended message is conveyed unambiguously, thus supporting the credibility and professionalism of the writing.
