Morphology

coordinated + universal + time

The meaning is a direct combination of 'coordinated' (arranged together), 'universal' (applying everywhere), and 'time' (measurement of moments), so a learner who knows these words can infer it refers to a standardized/global time system. Although it is a technical term, its sense is compositional and widespread across languages (e.g., Spanish 'Tiempo Universal Coordinado'), making it immediately understandable.

Etymology

Coordinated universal time gets its name from the idea of many clocks being set together for the whole world: coordinated means the clocks are set to agree and universal means 'for everyone'. Scientists use very accurate atomic clocks and sometimes add small extra seconds so the time keeps matching the Earth's spin, so coordinated universal time is the single time people use for schedules around the world.
