stair

Etymology

It is inherited from Middle English steir, also steyer,^[2][3][4] inherited from Old English stǣger (“stair, flight of steps”),^[5][4][6][7] from Proto-Germanic *staigriz,^[8][9] Barnhart's and the OED's *staigrī,^[5][10] a derivative of the Germanic base *staig-, *stīg- (“to climb”).^[5][7][11] The same base gave stīgan (“to climb, go up or down”) and stīg (“narrow path”),^[10][2][12] and English stile, stirrup and sty, a swelling on the eyelid.^[11] It is cognate with Middle Dutch steger (“ladder”) and Dutch steiger (“scaffolding, quay, landing stage”),^[2][5][4] with Middle Low German steiger,^[5][13] and, through the verb, with German steigen (“to climb”), Old Norse stíga and Gothic 𐍃𐍄𐌴𐌹𐌲𐌰𐌽 (steigan, “to go up, rise”).^[10][2][14] The root is Proto-Indo-European *steigh- (“to go, rise, stride, step”),^{[4][6][10][11]} which also gave Old Irish tīagu (“I walk”).^[2][11]

Earliest recorded meaning

An ascending series of steps, a flight of stairs: in Old English, about 1000, in Ælfric's Glossary.^[10][5] The Middle English form steire is recorded probably before 1200.^[10]

Semantic evolution

In Old English the word meant the whole flight of steps,^[5][4] and that collective singular survives in Scotland and in literary use.^[15][13][12] The plural stairs for a flight is recorded from the late 14th century, in Trevisa,^[5][4][15] and stair for a single step from 1530, in Palsgrave.^[5][4] Johnson (1755) noted that the word was once used for the whole order of steps, but now meant only one flight.^[16] A figurative "step" in an ascent or a scale of dignity is found from about 1225, in the Ancrene Riwle, to 1640,^[5][4] and the figurative sense of a means of rising in rank or virtue from 1596.^[5] Chaucer used stair for a degree of a circle (about 1374).^[5] The compounds staircase (1624) and stairway (1708) followed.^[10] Police slang of the 1950s called a thief who walks into unsecured offices a stair-dancer.^[17]
