  • Indeed, in 1991, the annual average ex-vessel red sea urchin price differential between Santa Barbara and Fort Bragg was $0.26/kg, rising to $0.42 in 1992 and $0.54 in 1993.

Is there any reason to mess with our differentials with the tranny?

Morphology

differential = differ (semi-transparent) = differ + ential

The mechanical device meaning is not immediately obvious from 'differ'.

Etymology

Differential (noun, car part) comes from the same root as different and difference, meaning 'not the same'. A vehicle differential lets two wheels turn at different speeds, so the origin is easy to remember: it makes the wheels move 'differently'.
