Canvas

Canvas: the word itself is derived from cannabis, from which it was historically made. Now mostly made from cotton and or linen – it was made from hemp (also known as cannabis) in the early days.

 French Impressionists used hemp or linen to make their canvas as a painting surface. When hemp or cannabis became rare (due in part to prohibition), linen began to take over as a cheaper alternative.

According to historical research, the word may have French and Latin roots. Canevaz and canevas may have been previous spelling of this very old word.

The word “canvas” is derived from the 13th century Anglo-French canevaz and the Old French canevas. Both may be derivatives of the Vulgar Latin cannapaceus for “made of hemp”, originating from the Greek κάνναβις (cannabis).
