noun, masculine/tɔ̃.ljø/plural: tonlieux
a feudal tax paid by stallholders at a fair or market
Inherited from Old French tonliu, tolniu, from Vulgar Latin *tolōnēum, variant of Latin telōnēum (“tollbooth, custom house”), from Ancient Greek τελωνεῖον (telōneîon, “custom house”). Influenced by lieu due to folk etymology.
