Blow

According to Cassidy, the English word blow, as in hit or strike, comes from the Irish bualadh. This is rubbish, of course. Blow is an old Germanic word. It has been in
English since at least the mid-15^th century and has German cognates such as bleuen. It is not the same word as blow in the sense of the wind blowing, which comes from Old English blawen. One or both of these words may be cognate with Irish bualadh. (In other words, they may share a root in common thousands of years ago.) I don’t know. But neither of them comes from Irish bualadh. Cassidy’s claim is simply nonsense, like almost everything in this idiotic, childish travesty of a book.
