An Etymological Dictionary of the German Language/Annotated/schrötig

by Friedrich Kluge

schrötig, in ein verschrötiger Baum, ‘a tree from which four posts can be made,’ early Modern High German only, is probably connected with Old High German viorscôȥȥi, ‘four-cornered’; compare Middle Dutch vierscoot, ‘square-built, thick-set,’ earlier Low German vierschötig, ‘four-cornered’; compare Schoß (3).
