I went to the toilet to drop a turd.
Origin of turd
- Middle English from Old English tord der- in Indo-European roots
From American Heritage Dictionary of the English Language, 5th Edition
- From Middle English toord, tord, from Old English tord (“piece of excrement, dung, filth "), from Proto-Germanic *turdÄ… (“mud, manure"), from Proto-Indo-European *der- (“to split, flay"). Cognate with Middle Dutch tord (“lump of excrement"), Old High German zort (“dung, excrement"), Old Norse torÃ°- (“dung-", in compounds), Old English tyrdel (“dropping, small piece of excrement"). More at tear, treddle.
