📌 Good to know
Some dictionaries also list canvas as a less common spelling of the asking verb. For writing, canvass is the spelling to learn when you mean asking people.
The cloth word comes from a Latin word for hemp, the plant whose fibres can be made into strong cloth. The history of the asking verb is less certain, and you don't need it to tell the two words apart.

💡 The OddLingo Trick
Canvas is something you can touch: stretched cloth for a painting, a tent or a sail. Canvass is an action: you walk around, ask questions and listen. If you can hold it, it's canvas. If you have to do it, it's canvass.
