stair

stair: [OE] A stair is etymologically something you ‘climb’. The word goes back to a prehistoric Germanic *staigrī (source also of Dutch steiger ‘scaffolding’). This was derived from the base *staig-, *stig- ‘rise’, which also produced English stile, stirrup, and sty in the eye. And this in turn went back to an Indo-European *steigh- ‘go, rise’, source also of Greek steíkhein ‘stride, go’ and Irish tiagu ‘go’.
=> stile, stirrup, sty

Old English st?ger "stair, flight of steps, staircase," from Proto-Germanic *staigri (cognates: Middle Dutch stegher, Dutch steiger "a stair, step, quay, pier, scaffold;" German Steig "path," Old English stig "narrow path"), from PIE *steigh- "go, rise, stride, step, walk" (cognates: Greek steikhein "to go, march in order," stikhos "row, line, rank, verse;" Sanskrit stighnoti "mounts, rises, steps;" Old Church Slavonic stignati "to overtake," stigna "place;" Lithuanian staiga "suddenly;" Old Irish tiagaim "I walk;" Welsh taith "going, walk, way"). Originally also a collective plural; stairs developed by late 14c.
