IPA: /ˈkærəˌfʊr/
KK: /kærˈfɜr/
A place where two or more roads meet, often used to refer to a public square or plaza.
The carrefour was bustling with people and street vendors.
Carrefour is derived from the Old French "carrefour" (meaning crossroads), which is a combination of "carre" (meaning square or four-sided) and "four" (meaning to cross). The term originally referred to a place where roads cross each other, forming a square or intersection.
Imagine a 'crossroads' where paths 'cross' ('four') to form a 'square' ('carre') — that's what a carrefour is, a place where roads meet.
