The term 'give permission to' can be expressed in two words: 'LET' and 'ALLOW'. 'LET' is a three-letter word meaning to permit or give permission, while 'ALLOW' is a five-letter word with the same meaning. This phrase is commonly used to grant someone the authority to do something, such as allowing a child to stay out late or permitting a friend to borrow something. It is also used to express permission in a more formal setting, such as when a boss gives an employee permission to take a day off.
