    Usage notes
    The use of "let" to introduce an imperative may sometimes be confused with its use, as its own imperative , in the sense of "to allow". For example, the sentence "Let me go to the store." could either be a second-person imperative of "let" (addressing someone who might prevent the speaker from going to the store) or a first-person singular imperative of "go" (not implying any such preventer).
