Purview is a noun that refers to the scope of influence or concerns.
Coming from late Middle English with the original meaning of ‘foreseen,’ our word of the day’s use has shifted over the years. It is now used to refer to someone’s range of experience or their ‘view.’ Here’s an example:
Terry was outside of his purview when he gave us medical advice. Looking back, we might have been better off seeking the counsel of a lawyer instead of my plumber.
