An Etymological Dictionary of the German Language/Annotated/pochen

by Friedrich Kluge

pochen, verb, ‘to knock, beat,’ from Middle High German puchen, bochen; compare Middle Low German boken, Dutch pogchen, ‘to boast,’ English to poke. The Modern High German verb is not borrowed from the Low German; compare Alemannian bochen. It is derived from a Teutonic root puk, buk.
