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.
Daniel Cassidy informs us in his etymological hoax How The Irish Invented Slang, that the obsolete slang term for the moon, oliver, comes from the Irish oll ubh óir, a great golden egg. This is one way (a wrong way – it should be ollubh óir) of saying big golden egg in Irish, though certainly not the usual way (ubh mhór óir) but why óir? Why golden? Surely the moon is always regarded as silvery, in contrast to the golden quality of the sun? I don’t know the real origin of oliver though folklore apparently links it to Oliver Cromwell and his bald pate. But I don’t believe it comes from oll ubh óir, which makes no sense at all.
