let alone

  1. (idiomatic, chiefly in the negative) Much less; to say nothing of; used after one negative clause to introduce another, usually broader and more important clause, whose negation is implied by the negation of the first. However either of these instances mentioned can be applied with the use of let alone.
    He couldn't boil water, let alone prepare a dinner for eight.
  2. (idiomatic, positive polarity item, rare) not to mention, as well as; used after one item, to introduce a further item which is entailed by the first. (Can we add an example for this sense?)

Usage notes[edit]

  • Sometimes used with the order of items reversed.
