Usage note
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 leave¹.

Etymonline

Word Origin & History

let

O.E. lætan "to allow, let go, bequeath, leave," also "to rent" (class VII strong verb; past tense let, pp. læten), from P.Gmc. *lætan (cf. O.S. latan, O.Fris. leta, Du. laten, Ger. lassen, Goth. letan "to leave, let"), from PIE *le(i)d- "to leave behind, leave, yield" (cf. L. lassus

"faint, weary," Lith. leisti "to let, to let loose"). The primary sense appears to be "to let go through weariness, to neglect." Obsolete let (n.) "hindrance" is from O.E. lettan "hinder, delay," from P.Gmc. *latjanan, related to Mod.Eng. late. Let on "reveal, divulge" is from 1630s; let up "cease, stop" is from 1787.

let

"hindrance," 1175, from O.E. lettan "hinder, delay," from P.Gmc. *latjanan (cf. O.S. lettian "to hinder," O.N. letja "to hold back," O.H.G. lezzen "to stop, check," Goth. latjan "to hinder, make late," O.E. læt "sluggish, slow, late"); see late.

Matching Quote

"When I was in grade school and we had to write papers about what we wanted to be when we grew up, I wanted to be a social worker or a missionary or a teacher. Then I got involved with tennis, and everything was just me, me, me. I was totally selfish and thought about myself and nobody else, because if you let up for one minute, someone was going to come along and beat you. I really wouldn't let anyone or any slice of happiness enter.... I didn't like the characteristics that it took to become a champion."
