1580s, "to cover with a fort," from en- (1) "make, put in" + sconce "small fortification, shelter," perhaps via French, probably from Dutch schans "earthwork" (compare Middle High German schanze "bundle of sticks"), which is of uncertain origin. Hence, "to fix firmly, settle" (1590s). Related: Ensconced.
