redshifted

The term 'redshifted' is a modern scientific compound, directly built from common English elements to describe a precise physical phenomenon. The word 'red' anchors the concept in the visible spectrum, where longer wavelengths correspond to the color red. The component 'shift' conveys the idea of movement or change in position, specifically the displacement of spectral lines. The suffix '-ed' transforms the verbal idea into an adjectival state, describing radiation that has undergone this change. Thus, the literal construction "moved-toward-red" provides a perfectly logical and transparent description of the observed increase in wavelength, whether caused by relative motion or cosmological expansion.
