🌳Etymology
Origin
Visible derives from Latin videre (to see), with the suffix -ible (capable of) added to form 'able to be seen'. Light comes from Old English leoht, meaning 'illumination or radiance'. The compound term refers to electromagnetic radiation perceptible to the human eye, distinguishing it from infrared and ultraviolet wavelengths.
Breakdown
vid- (to see, from Latin videre) + -ible (capable of, able to be) + light (illumination, from Old English leoht). Together: 'light capable of being seen' or radiation visible to human perception.
