perspectief n (plural perspectieven, diminutive perspectiefje n)
From Old - or Middle French, from the first word of the Medieval Latin perspectiva ars (“science of optics”), the feminine of perspectivus (“of sight, optical”), from perspectus, the past participle of perspicere (“to inspect, look through”), itself from per- (“through”) + specere (“to look at”); the noun sense was influenced or mediated by Italian prospettiva, from prospetto (“prospect”).
