percept

A learned borrowing, after concept, from Classical Latin perceptum (“a proposition, principle, general idea”), from the neuter of perceptus (“perceived”), the past participle of percipiō (“to perceive”); see perceive. Coined by the Scottish metaphysician Sir William Hamilton, 9th Baronet (1788–1856), in Lectures on Metaphysics and Logic, published posthumously in 1860 (see the quotation).

Learned borrowing from Classical Latin percept-, the past participial stem of percipiō (“to perceive”). In etymology 2 sense 2, perhaps independently from percept (“something perceived”).
