Explanation
OK is a very common word used to show agreement, acceptance, or that something is fine. People use it in conversations, messages, and writing. When someone asks a question, replying with “OK” means you agree or understand. It can also describe a condition, meaning not bad and not excellent, just fine. Sometimes OK explains how something was done, used to mean “well” or “satisfactorily”; for example, she did OK on the test (meaning she did well). It can also be a thing someone says, as the name of an agreement or approval, like he gave his OK. The word is informal and friendly. Depending on tone, “OK” can show happiness, permission, or simple confirmation.
