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.
Wherever you look, in any English dictionary, you will find that this word is described as deriving from Irish or from Scots Gaelic go leor with the same meaning. For some reason, Cassidy fails to mention this fact. The reason is probably that according to Cassidy, the makers of English dictionaries are determined to deny the influence of Irish on English. As this example shows, where genuine evidence exists, lexicographers are quite willing to accept Irish derivations.
