A recent exchange with one of Cassidy’s supporters on the comments section of this blog (which I have since removed) had one useful outcome, as I realised that my treatment of Cassidy’s claims about the origins of the word boogaloo were not detailed enough.
The origins of boogie are mysterious enough. The known facts are that boogie was originally recorded in 1917 as a term for a rent party. Among poor black people, when they were unable to make the rent, they had a party (with alcohol during Prohibition) as well as music to raise the money to keep them from eviction. According to the excellent Etymonline, a song title “That Syncopated Boogie-boo” first appears in 1912. The style of music known as boogie or boogie-woogie dates back to 1928. The term boogaloo is quite late, being recorded first in the 1960s.
Cassidy ignores these subtleties and claims that the word boogie is from the Irish bogadh. He doesn’t mention boogie-woogie (because he can’t twist it into an ‘Irish’ form) but emphasises the late word boogaloo.
Bogadh is an Irish verbal noun. Its main meaning in modern Irish is ‘to move’. Because of this, Cassidy doesn’t mention the rent party origin, emphasising instead the meanings of dancing and movement. The word bogadh is a bad match in terms of sound. Bogadh is pronounced boggoo in the north and bogga in southern Irish.
As we have said, boogaloo is a very late development of the word boogie. Cassidy claims that it comes from an ‘Irish’ phrase bogadh luath. The word luath has the primary meaning of early, but can also mean fast. Because of this ambiguity, it is unlikely that it would be used in phrases like this rather than a word that unambiguously means fast, like gasta, tapa or mear.
To convince ignorant and gullible people that bogadh luath is an Irish phrase, Cassidy gives several examples of sentences using it. He claims that Níl bogadh luath ann means ‘he is unable to move fast’, while according to him, bogadh luath as áit means ‘to move fast out of a place; to boogaloo out of a joint’. Where did these examples of bogadh luath in use come from?
The answer, of course, is that they are crude fakes manufactured by Cassidy. He copied two phrases from Ó Dónaill’s dictionary, Níl bogadh ann and bogadh as áit, and then randomly stuck the word luath into them and pretended that they would make sense.
In fact, Níl bogadh ann is an all-or-nothing kind of a phrase. The best comparison would be expressions like the English ‘There wasn’t a peep out of him’. Just because you can say that doesn’t mean you can say ‘There wasn’t a big peep out of him’ if he spoke a little bit.
As for bogadh luath as áit, if you said ‘they moved quickly out of the house’, you would have to say bhog siad (or bhogaidis) as an áit GO luath. You need the adverbial particle go. People don’t bogadh luath or dul gasta or teacht réidh in Irish. Of course, Cassidy was completely ignorant of the Irish language and wouldn’t have had a clue what was right and what was wrong, either in terms of Irish grammar or personal morality.
