spin-off

We are about to broach the fraught saga of the Circle Line, but there is another Metropolitan spin-off that comes first, one that has always appealed to me by the baleful beauty of its name: the City Widened Lines or 'The Widened Lines' for short.

Space research often provides a spin-off for everyday technology.

"Frasier" was a spin-off from the sitcom "Cheers".
