Etymology
The word visor originates from the Anglo-French viser and Old French visiere, meaning the face guard of a helmet. These terms derive from the Latin visus, meaning "sight" or "face," which itself comes from the past participle of videre, "to see." The literal logic is clear: a visor is an instrument for seeing or a part that relates to the face and sight. Over time, its meaning specialized from a general face covering to the protective or shading screen on headgear, maintaining the core semantic link to vision and the face.
Analysis
vis is from Latin visus (sight, thing seen) and videre (to see), acting as the core root. or is a Latin-derived agent noun suffix indicating a person or thing that performs an action.
