filch
To steal, or purloin. Originally a cant word, derived from the FILCHES, or hooks, thieves used to carry, to hook clothes, or any portable articles from open windows.—Vide Decker. It was considered a cant or gipsy term up to the beginning of the last century. Harman has "FYLCHE, to robbe." Probably from "FILICHI," Romany for a handkerchief.
