What is the difference between "affect" and "effect"?

"Affect" is a verb meaning to influence or produce a change in something or someone. "Effect" is a noun meaning the result or consequence of something. So, "affect" is used to describe the action of causing a change, while "effect" is used to describe the outcome or result of that change. For example, "The new policy will affect the company's profits" and "The effect of the policy on the company's profits was significant."
