What is the difference between let, allow, and permit?

While “let,” “allow,” and “permit” are often used interchangeably to convey permission or authorization for something to happen, there are subtle differences in their usage:


Informal: “Let” is typically used in informal contexts and conversations.

Personal Control: It often implies giving someone personal control or permission over a situation.

Example: “She let her children stay up late to watch a movie.”


Formal and Neutral: “Allow” is more formal and neutral compared to “let.”

General Permission: It is commonly used to express general permission or authorization.

Example: “The Company allows employees to take paid time off for vacation.”


Official Authorization: “Permit” is the most formal of the three terms.

Legal or Official Contexts: It is typically used in legal or official contexts to denote official authorization or licensing.

Example: “You need a permit to operate a food truck in the city.”

In summary, while all three terms convey the idea of giving permission, “let” is more informal and implies personal control, “allow” is neutral and commonly used for general permission, and “permit” is the most formal and used in legal or official contexts for official authorization.
