Hello, Do you know the oldest known written down sentence in your mother tongue? Do you know circumstances when it was written? How much this spelling is different from modern language? Is it possible and easy to guess its meaning? I give the known oldest Polish sentence in Old Polish spelling . Day ut ia pobrusa, a ti poziwai. Daj, ać ja pobruszę, a ty poczywaj. It means: Let me grind (I will curl the quern), and you rest (or see as it to do). This sentence was said by Czech Boguchwal to his Polish wife. So the first written sentence in Polish was just said by some Czech. It was found in the Latin text around 1270 year in the abbey of Cistercian monks chronicle written down in Latin.
