usage note for let
Let us is used in all varieties of speech and writing to introduce a suggestion or a request:
Let us consider all the facts before deciding. The contracted form
let's occurs mostly in informal speech and writing:
Let's go. Let's not think about that right now. Perhaps because
let's has come to be felt as a word in its own right rather than as the contraction of
let us, it is often followed in informal speech and writing by redundant or appositional pronouns:
Let's us plan a picnic. Let's you and I (or
me )
get together tomorrow. Both
Let's you and me and
Let's you and I occur in the relaxed speech of educated speakers. The former conforms to the traditional rules of grammar; the latter, nonetheless, occurs more frequently. See also
