Conurbation is a noun that refers to an extended urban area.
The Latin prefix C-O-N means ‘together.’ Combined with U-R-B for ‘city,’ we get our word of the day which refers to a place where serval towns are merged into a giant urban area.
Having grown up in the conurbation of southern California, I’m accustomed to gigantic urban locations. Living in a large city that is isolated from other large cities seemed odd to me.
