a mistake is an action or decision that is not in accordance with accepted rules or logical principles, or based on incorrect or wrong information. It usually carries the connotation of being an unintentional error, rather than a deliberate choice. Some common examples of mistakes include spelling errors, misplacing or misusing a word, misreading an instruction, making a wrong decision, using the wrong assumptions or data to draw a conclusion, or making a miscalculation in mathematics.

2. She knew he was regretful for the mistake he had made.
3. He realized he had been making a mistake all night when revising for the exam.
mistake should be used when referring to an action or decision that is unintentional, rather than when referring to a deliberate action separate from honest errors. It can also be difficult to distinguish when an action is a mistake in the technical sense, versus simply a decision that resulted in a negative outcome.

'mistake' as a verb is often followed by an object (the thing being misunderstood) and then 'for' followed by another object (the incorrect interpretation or identification). For example
'mistake A for B.' A common error is the omission of 'for' when using 'mistake' as a verb. For instance, 'I mistook him his brother' is incorrect. The correct form is 'I mistook him for his brother.' The past tense of 'mistake' is 'mistook,' and the past participle is 'mistaken.'
