Sense: noun/1
For noun sense 1, permission is the everyday word for being allowed to do something by a person or group with authority. Approval is broader: it can mean support for an idea, plan, or behavior, not only the right to act. Consent is more formal and is common in law and medicine, especially when the person affected agrees. Leave is a formal or slightly old-fashioned word, often found in set phrases such as ask leave to speak. Authorization is formal and often appears in business, security, or legal settings, especially when rules or documents matter. You ask a teacher for permission to leave class, sign a consent form before surgery, and need authorization to enter a secure lab.

Etymology
Permission came into English from Latin through French. Its older Latin source meant letting something go through or allowing it, and English later used permission both for the act of allowing and for the formal approval itself.
