Etymology

Origin of warren

1350–1400; Middle English warenne < Anglo-French; Old French g ( u ) arenne < Germanic *warinne game park, equivalent to *war- (base of *warjan to defend) + *-inne feminine noun suffix

Explanation

When Bugs Bunny outruns Elmer Fudd and vanishes down his rabbit hole, he's escaping into a warren — a network of underground tunnels where rabbits live. A warren isn't just the maze-like tunnels where rabbits live. You may encounter a warren of subway tunnels or a warren of interconnected bomb shelters. Bring those narrow paths above ground and cluster them with homes and you have another kind of warren, or a maze-like residential area.
