1) One who avouches or guarantees.
It is generally an uncommon word but it featured more than twenty times in a document of 1631 which recorded the sale of horses at Adwalton horse-fair. By an Act of 1589 no sale was legal without the honesty of the vendor being vouched for by ‘A sufficient and credible person’. Typical of the numerous entries is: 1631 Jerimye Crabtree of Greetland ... clothier sould one fle bitten nagge trots unto Geo. Burnstone of Potter Newton ... price xxxs vjd. Walter Harrison of Ealand avowcher.
