canvas: [14] Canvas is related ultimately to hemp, for originally canvas was a cloth made from hemp. Latin cannabis (from the same source as English hemp) produced the Vulgar Latin derivative *cannapāceum, which passed into English via Old Northern French canevas. The verb canvass [16] appears to come from the noun: it originally meant ‘toss in a canvas sheet’, and this was perhaps the basis, via an intermediate ‘criticize roughly’, of the metaphorical sense ‘discuss thoroughly’. It is not clear where the political meaning ‘solicit votes’ came from. => cannabis, hemp
canvas (n.)
"sturdy cloth made from hemp or flax," mid-14c., from Anglo-French canevaz, Old North French canevach, Old French chanevaz, literally "made of hemp, hempen," noun use of Vulgar Latin adjective *cannapaceus "made of hemp," from Latin cannabis, from Greek kannabis "hemp," a Scythian or Thracian word (see cannabis).
Latin adjectives in -aceus sometimes were made in Romanic languages into nouns of augmentative or pejorative force. Especially as a surface for oil paintings from c. 1700; hence "an oil painting" (1764).
