ほざく

According to one theory, from Old Japanese 呪く (<posaku> → hosaku, “to curse”), originally to be the same word with 祝く (<posaku> → hosaku, “to say words of celebration”), from the same root with 祝く (<poku> → hoku, “to chant words of celebration for hoping for good results; to cast a curse and consult the divine will”).

Compare ふざける (fuzakeru, “to joke around”) and dialectal words ほたく (hotaku, “(dated, chiefly Sado) act violently, struggle”), ほだく (hodaku, “(Kantō) (derogatory) to say; to make noise; to joke around”) and ほたえる (hotaeru, “(chiefly Kansai, Chūgoku and Shikoku) to joke around, to make noise”).
