What's the difference between "ask" and "request"?

“Ask” is often used in everyday conversations, such as “Can you pass me the salt?” or “I’d like to ask you a question.” It suggests a more casual and conversational tone. On the other hand, “request” is typically used in more formal settings, such as in written communications, business transactions, or official procedures. For example, “I would like to request a meeting with the manager” or “Please submit a written request for time off.” “Request” implies a more formal and polite way of asking for something, often with an expectation of a response or action.
