From Middle English pouren (“to pour”), of uncertain origin. Perhaps from Old Northern French purer (“to sift (grain), pour out (water)”), from Latin pūrō (“to purify”), from pūrus (“pure”). Compare Middle Dutch afpuren (“to pour off, drain”). To pour displaced several Middle English verbs: schenchen, schenken (“to pour”), from Old English sċenċan (“to pour out”) and Old Norse skenkja, from Proto-Germanic skankijaną. Compare dialectal English shink, skink. yeten, from Old English ġēotan (“to pour”), from Proto-Germanic geutaną. * birlen (“to pour, serve drink to”), from Old English byrelian (“to pour, serve drink to”). * hellen (“to pour, pour out”), from Old Norse hella (“to pour out, incline”). * temen (“to pour out, empty”), from Old Norse tœma (“to pour out, empty”). Compare archaic English teem.
