TWEED, a cloth, so called from the name of the river which falls into the sea at Berwick, where it is largely manufactured. It is said, however, that some cloth called on an invoice tweels, or tweeled, that is, woven diagonally, having been sent to London, the word, which was blotted or imperfectly written, was misread Tweed, and as the cloth was manufactured in the valley of the Tweed, and the designation tweed was consequently an appropriate one, it was allowed to stand, even after the error had been detected.
