Common mistakes	'Adapt to' vs. 'adapt for': Confusing these phrases., Using 'adopt' instead of 'adapt': These words have different meanings., Omitting the object: Forgetting to specify what is being adapted.	Confusing with 'change' - 'alter' usually implies a more significant adjustment., Using 'alter' without an object - it should always follow an object., Incorrectly using 'altered' as a noun.	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.
Usage notes	Use 'adapt' when talking about making changes to fit new conditions or requirements. It's appropriate in both formal and informal contexts but is often used in discussions about learning or adjusting to new environments.	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.
