Emily Dickinson Lexicon

RE-GRATE, v.t. [Fr. regratter, to scratch again, to new-vamp, to regrate, or drive a huckster's trade; re and gratter, to grate, to scratch, to rake.]

1. To offend; to shock. [Little used.]
2. To buy provisions and sell them again in the same market or fair; a practice which, by raising the price, is a public offense and punishable. Regrating differs from engrossing and monopolizing, which signify the buying the whole of certain articles, or large quantities, and from forestalling, which signifies the purchase of provisions on the way, before they reach the market. – Blackstone.
