Morphology

graywater = gray + water (semi-transparent) = gray + water

Morphologically a clear compound 'gray' + 'water', but the precise technical meaning (wastewater from sinks/showers excluding toilet waste) is specialized and not fully predictable for an average learner.

Etymology

Graywater comes from the simple parts gray and water, and it names water from sinks, showers, and washing machines that is 'not toilet waste' and can be reused for things like watering plants. Think of 'gray' as the color between 'clean' and 'dirty', which helps explain why this water can be reused.
