Morphology

Greenwich + time

Given knowledge of the place-name 'Greenwich' (noted for Greenwich Mean Time) and the noun 'time', a B1 learner can directly infer this refers to the time measured at Greenwich/the Prime Meridian and used as a standard. The meaning is a straightforward compositional place+time construction found across languages, so it is immediately derivable from the constituents.

Etymology

Greenwich Time comes from the town of Greenwich in England, where a special place kept the official clock on the zero line that divides east and west of the world. That's why Greenwich Time means the standard or 'world' time used for schedules and comparing clocks.
