perceptual

Etymology

It is formed from English percept + -ual,^[2][3] on the model of conceptual.^[3][4][5] The OED derives it from the past participle stem of Latin percipiō (“to perceive”), the source of perceive, with the suffix -ual.^[4] The Latin verb meant to obtain or seize entirely, and figuratively to grasp with the mind.^[2] Percept, from 1837, was itself formed on the model of concept.^[2]

Earliest recorded meaning

Of or relating to perception; of the nature of percepts: 1878, in Shadworth Hodgson's The Philosophy of Reflection.^[4][6] Etymonline dates the word to 1852,^[2] and Dictionary.com to 1875–80.^[3]

Semantic evolution

The word arose in 19th-century philosophy, beside percept and conceptual, and kept the sense "of or relating to perception".^[4][2] Merriam-Webster sets it against abstract concepts and also uses it of sensation as conditioned by experience.^[6] In psychology the Shorter Oxford records perceptual defence, a raised threshold of perception when a stimulus is emotionally unwelcome, and the compound perceptual-motor.^[5] The Oxford Dictionary of English illustrates the modern use with a patient whose perceptual problems keep him from judging distances.^[7]
