sentient

Etymology

It is borrowed from Latin sentiēns (“feeling”), the present participle of sentiō (“to feel, perceive”),^{[2][3][4][5][6]} with the English suffix -ent.^[4][7] The Latin verb is the source of sense.^[3][4][6] The American Heritage Dictionary traces it to Proto-Indo-European *sent-.^[5]

Earliest recorded meaning

As a noun, that which has sensation or feeling: 1603, in Philemon Holland's translation of Plutarch's Morals.^[2] The adjective, capable of feeling, is first recorded in 1632, in the second edition of Guillim's Display of Heraldrie,^[2][8][4] and Etymonline dates it to the 1630s.^[3] Dictionary.com dates the word to 1595–1605.^[9]

Semantic evolution

The word began in philosophical use, for a being that has the power of sensation.^[2][3] Johnson (1755) entered both the adjective, "perceiving; having perception", and the noun, "he that has perception", with a quotation from Glanvill.^[10] From 1814, in Southey, it also meant conscious or aware of something,^[2] and in 1822 physiology applied it to organs and tissues that respond to stimuli.^[2] The noun sentience is first found in 1839, in Poe's The Fall of the House of Usher.^[4] Merriam-Webster now defines the adjective as capable of sensation and of at least rudimentary consciousness,^[8] and Collins marks the noun as rare.^[11]
