palpable

Etymology

It is borrowed from Middle French palpable (“that may be touched”) and directly borrowed from Late Latin palpābilis (“that may be touched or felt”),^[2][3][4][5] from Latin palpō (“to touch gently, stroke”) and the suffix -bilis.^[2][6][7] The OED records the Latin adjective in the sense "that may be touched" from the Vetus Latina, and in British sources from before 1215 also as "easily perceptible, obvious"; the Middle French word is recorded from about 1365, and in figurative uses from the 15th century.^[2] The American Heritage Dictionary and Watkins connect the Latin verb with Proto-Indo-European *pāl-, the root of feel,^[8][6] and Ayto and Barnhart also relate it to that verb,^[9][3] but Etymonline reports that de Vaan rejects the connection on phonetic grounds and finds no known etymology; some sources think the verb imitative.^[6] The same Latin verb gave palpitate, palp and palpate.^[9][10]

Earliest recorded meaning

Barnhart's first record is from about 1380, in Chaucer's House of Fame, with the sense "plain, evident",^[3] but Skeat's Chaucer glossary and Benson's concordance gloss that use as "capable of being felt, tangible".^[11][12] The OED's first record, from 1395, is in a Wycliffite text on the sacrament of the altar, which is "visible and palpable".^[2][5]

Semantic evolution

The word passed from touch to the other senses and to the mind.^[2][13] Before 1425 the Lantern of Light spoke of "dercknesse palpable, þat is, so þick þat it may be gropid",^[5][2] echoing the Vulgate's darkness that may be felt (Exodus 10:21);^[2] this use, of darkness, heat or mist so intense as to seem tangible, later spread to feelings and atmospheres.^[2][13] From about 1435, in Lydgate, it also meant plainly noticeable by sight or another sense; before 1460, in Bokenham, it already meant obvious to the mind.^[2] Hoad dates the sense "evident, manifest" to the 17th century.^[14] Johnson (1755) gave "perceptible by the touch", quoting the dagger in Macbeth, and "gross; coarse; easily detected".^[15] According to Word Origins, Osric's "a very palpable hit" in Hamlet still uses the literal sense, "truly feelable".^[10][16] The medical sense, perceptible by palpation, is recorded from 1897.^[2][13] From 1585 to 1607 the word was also used as an adverb, for palpably.^[2]
