Etymology

Compound of Buche +‎ Ecker. The now rare simplex Ecker from Middle High German ackeran, eckern; only once attested in Old High German as ekarn. Ultimately from Proto-Germanic *akraną, whence also English acorn. An original neuter or masculine whose final -n was interpreted as a plural morpheme and which was subsequently made into a feminine. Kluge (24th edition) considers it a chiefly Low German word (compare Middle Low German ākeren, eckeren).
