chadとは 意味・読み方・使い方

語源 1

Uncertain; possibly from the English slang term chat (“louse”). The word predates the chadless punch, which therefore cannot be its origin, and a derivation from Scots chad (“river gravel”) stated in some dictionaries is now thought to be nothing more than guesswork.

   • 2000 December 12, Supreme Court of the United States, per curiam, “Bush v. Gore”, in United States Reports, volume 531, page 98 at 105:

     Much of the controversy seems to revolve around ballot cards designed to be perforated by a stylus but which, either through error or deliberate omission, have not been perforated with sufficient precision for a machine to count them. In some cases a piece of the card—a chad—is hanging, say by two corners. In other cases there is no separation at all, just an indentation.
