Past tense of disjask; to remove the jask or outer skin from something, particularly grain or seeds.
From dis- + jask (from Dutch or Low German origin, meaning 'hull' or 'husk'). This is an archaic agricultural term referring to the process of dehusking grain.
Disjask is one of those wonderfully specific old words that shows how farming communities had precise vocabulary for every step of food processing—there was a word for practically every grain-related task, but most have disappeared as industrial agriculture replaced hand labor.
