The difference between "let" and "allow" lies in their level of formality, grammatical structure, and implied personal involvement. Here are the key distinctions:
- Let: This term is typically used when the subject actively grants permission, often in informal contexts. It can sometimes imply a personal willingness or choice on the part of the subject in granting permission, suggesting a more voluntary act of allowing something. The verb that follows "let" is in bare infinitive form (e.g., "The teacher let the students leave early").
- Allow: This term focuses on the permission itself without necessarily emphasizing the subject's personal involvement. It is more neutral and does not necessarily convey personal involvement or preference. "Allow" is followed by an object and a to-infinitive clause (e.g., "They do not allow students to use calculators in exams").
In summary, "let" is more informal and often implies personal involvement in granting permission, while "allow" is more neutral and focuses on the permission itself. Both terms are used to give someone permission to do something or not prevent them from doing it.
