eyesight
UK: ˈaɪsaɪt | US: ˈaɪsaɪt
n. the ability to see; vision
n. the range or power of vision
The word "eyesight" is a compound of "eye" (from Old English ēage, meaning the organ of vision) and "sight" (from Old English siht, gesiht, meaning vision or the act of seeing). The combination directly reflects the literal meaning—the power or faculty of seeing through the eyes. This transparent structure makes it easy to understand and remember, as both components retain their original meanings in modern English.
