Confused with 'exchange' which means to swap something., Using 'change' without an object, e.g., saying 'I change' instead of 'I change my clothes'., 'Changed' and 'change' misused in verb forms.	Confusing with 'modification', which is the noun form., Using 'modify' without an object, which is incorrect., Overusing 'modify' instead of synonyms like 'change' or 'adjust' in casual speech.	Confused with 'review'; 'revise' implies making changes, while 'review' means to look over., Using 'revise' without an object; it should always be 'revise something'., Using 'revise' in contexts that require 'edit'; be sure to consider the difference.

Usage notes	Use 'alter' when you want to indicate a change or modification. It is more formal than 'change'. Avoid using it for very minor or trivial adjustments.	Use 'change' when talking about making modifications or alterations. It's appropriate in both spoken and written English, in casual or formal contexts. Avoid using it in a situation that requires a more specific term, like 'transform' or 'alter'.	Use 'modify' when discussing changes to plans, documents, or objects. It's neutral, so it's appropriate in most contexts, such as academic or business settings.	Use 'revise' when talking about reviewing materials or making improvements. It's common in academic contexts but can also apply to work projects. Avoid using it in casual conversations.	Use 'transform' in contexts like science, personal change, or arts.
