permission
[U] Uncountable
This word carries a sense of hierarchy and authorization. It implies a power dynamic where one party holds the authority to grant or deny a request, making it more formal and restrictive than simply saying someone is allowed to do something. In legal or technical contexts, it refers to a specific right or privilege granted to a user or entity, such as file permissions in computing. This creates a feeling of a gated system where access is a binary state: either you have the permission or you are blocked.
Usually refers to the general concept of being allowed to do something, as in "Permission is required."
