Understanding the Verb "To Let"

What Does 'To Let' Mean?
The verb “to let” has several meanings, most commonly “to allow” or “to permit.” In British English, it also means “to rent out a property” (e.g., a house to let). Unlike regular verbs, “let” does not change in its past tense or past participle forms — they all remain “let.”

This irregularity makes it unique and important to learn for both grammar accuracy and fluency.
