eye

eye: [OE] In Old English times eye was ēage, which is related to a whole range of words for ‘eye’ in other European languages. Its immediate derivation is from prehistoric Germanic *augon, which was also the source of German auge, Dutch oog, Swedish ?ga, and many others. And *augon in its turn goes back to an Indo-European oqw-, which supplied the word for ‘eye’ to all the other Indo-European languages except the Celtic ones, including Russian óko (now obsolete), Greek ophthalmós, and Latin oculus (with all its subsequent derivatives such as French oeuil, Italian occhio, and Spanish ojo).

Amongst its more surprising English relatives are atrocious, ferocious, inoculate, ullage, and window.

eye (n.)

c. 1200, from Old English ege (Mercian), eage (West Saxon) "eye; region around the eye; apperture, hole," from Proto-Germanic *augon (cognates: Old Saxon aga, Old Frisian age, Old Norse auga, Swedish ?ga, Danish ?ie, Middle Dutch oghe, Dutch oog, Old High German ouga, German Auge, Gothic augo "eye").

Apparently the Germanic form evolved irregularly from PIE *okw- "to see" (cognates: Sanskrit akshi "the eye; the number two," Greek opsis "a sight," Old Church Slavonic oko, Lithuanian akis, Latin oculus, Greek okkos, Tocharian ak, ek, Armenian akn).
