For some time now, some of my on-line friends have advised me to provide a version of CassidySlangScam without the invective aimed at Cassidy and his supporters. In response to that advice, I am working on providing a glossary of the terms in Cassidy’s ludicrous book How The Irish Invented Slang with a short, simple and business-like explanation of why Cassidy’s version is wrong.
The word ‘puncher’ meant a cowboy. The word punch means to strike or to prod or to poke. It derives from French and has been in common use in English for six hundred years.
Daniel Cassidy, in his etymological hoax How The Irish Invented Slang, doesn’t mention these facts in his discussion of the word. He chooses instead to trace the word to the Irish paintéar, which he says means ‘a tying cord or rope, a noose, a lasso, a snare for catching animals …’ He cites Dinneen’s Irish dictionary as a source. Strangely, this isn’t what Dinneen’s dictionary says. Dinneen’s entry for paintéar begins thus: ‘a painter or panter, a snare, noose, gin or trap, a binding cable …’
In other words, this is an Irish word, certainly, but it was borrowed from the familiar English word painter, which is a nautical term for a rope used to tie up a boat. This is also of French origin (i.e. the English borrowed it from French) but unrelated to the French term which is really the origin of punch. Cassidy doctored the evidence to hide these facts that were inconvenient for his case.
