Root Explanation

Redshifted → It is formed from "red" (from Old English "read", meaning the color red) and "shifted" (from Old English "scyftan", meaning to cause to change or move). The term "redshifted" refers to the phenomenon where light from an object is shifted towards the red end of the spectrum, indicating that the object is moving away from the observer.

Memory Tip

Think of the color 'red' indicating a shift or change in light towards the red spectrum, which helps you remember that 'redshifted' means light that has changed towards red.
