canvass

Origin

The verb is derived from canvas (“type of coarse cloth woven from hemp”). The connection between “to toss (someone) in a (canvas) sheet; (by extension) to batter, beat, or thrash (someone or something); etc.” and “to seek the support of voters or a constituency in a forthcoming election or poll” is not entirely clear. The noun is derived from the verb. It has been suggested that noun sense 4.2 (“rejection (at an election, of a suit, etc.)”) may refer to the canvas bag used by journeymen mechanics which they used to pack up their tools after they had completed their jobs, in which case it is not derived from the verb but directly from canvas (noun).
