The word 'vision' entered English in the late 13th century via Anglo-French, tracing its core to the Latin verb vidēre, meaning 'to see'. Its Proto-Indo-European ancestor is weid-, meaning 'to see' or 'to know', a root that also gave rise to words like 'wisdom' and 'idea', linking the concepts of sight and knowledge. The suffix '-ion' transforms the action of seeing into a noun denoting the faculty, the act, or the product of sight. Over time, its meaning expanded from literal eyesight to include mental images, prophetic dreams, and, in modern usage, the capacity for imaginative foresight and strategic planning.

Structure: vis (see) + ion (noun suffix) 'vis' is from Latin visus (sight, thing seen), itself from the verb vidēre (to see). 'ion' is a noun-forming suffix of Latin origin, indicating an action, process, or state.
