Boh
A magical word greatly used to frighten children. "Boe," a Greek word is synonymous with the Latin "Clamor" signifying our English "cry;" and it is possible that the cry of the ox "boo' may have suggested this exclamation, as this sound would quite naturally be very terrifying to a young child. One also suspects some connection between this monosyllable and the "Bogle-boe or bwgwly of Welsh people. According to Warton, it was the name of a fierce Gothic general, whose name like those of other great conquerors was remembered as a word of terror. 66 Bohmius, Jean: The author of a work entitled Pyschologie, a treatise on spirits, published at Amsterdam in 1632. Of its author nothing is known.
