sulung

Etymology

Learned borrowing from Old English sulung, from sulh (“plough, ploughland”).

noun

1. (historical) A unit of land in medieval Kent, comparable to the hide and the carucate.
   The counting of sulungs (as of hides) is a horrible task on which no two scholars agree, and it is not surprising that before the age of the computer Jolliffe made slips and that his desire to find eighty-sulung units sometimes overrode the evidence or the geographical probabilities. 2000, Nicholas Brooks, Anglo-Saxon Myths: State and Church, 400–1066, page 57
