means A particular way of seeing or understanding something, shaped by where you stand — literally or mentally; also the technique that makes flat pictures appear to have depth.

from From Latin perspicere, "to see through, look closely," built from per- ("through") and specere ("to look"). It arrived in English through medieval optics, where perspectiva was the science of vision and lenses, before Renaissance painters borrowed it for the geometry of depth on a flat canvas — and only later did it drift into the figurative "point of view."
