a serve that strikes the net before falling into the receiver's court; the ball must be served again
leave unchanged; "let it be"
actively cause something to happen; "I let it be known that I was not interested"
make it possible through a specific action or lack of action for something to happen; "This permits the water to rush in"; "This sealed door won't allow the water come into the basement"; "This will permit the rain to run off"
a quantity of no importance; "it looked like nothing I had ever seen before"; "reduced to nil all the work we had done"; "we racked up a pathetic goose egg"; "it was all for naught"; "I didn't hear zilch about it"
in no way; to no degree; "he looks nothing like his father"
