Origin

Early 18th century: from French, from Italian pistone, variant of pestone 'large pestle', augmentative of pestello 'pestle'.

The Latin pistullum meant pestle (Middle English) and is the source of the botanical pistil (early 18th century) from its similar shape. From the same source Italian formed pestone for a large pestle or rammer, and this, via French, is the source of piston.

Rhymes

cistern, Liston, Wystan
