   • 1904, Леонид Андреев, “Отрывок пятый”, in Красный смех; English translation from Alexandra Linden, transl., The Red Laugh, London: T. Fisher, 1905:

     — Хорошо бы сейчас водки хлебнуть, — сказал студент.
     Мы хлебнули по глотку коньяку, и сон прошел совсем.

     — Xorošo by sejčas vodki xlebnutʹ, — skazal student.
     My xlebnuli po glotku konʹjaku, i son prošel sovsem.

     "It would be good to have a drop of vodka now," said the student.
     We drank a mouthful of brandy, and all sleepiness disappeared entirely.

A rare and awkward past passive participle хлёбнутый (xljóbnutyj) is sometimes found.
