If you click on this link to the debate (Ibn Warraq, Aronovitch, Murray vs. Glass, Ramadan, Dalrymple) you can hear William Dalrymple quoting, and misunderstanding, and misapplying, a statement by the historian of the Crusades Stephen Runciman. Fifty minutes and 31 seconds (51:31) into the debate, Dalrymple quotes Runciman on the interaction and fusion and so on "between Okkident and Orient." You heard right. Okkident.
As the Italians say: Accidenti.
Thoughts of phonetician Daniel Jones (hereinafter Jones #2) likely put you in mind of the respectful-affectionate name attached to Sir William Jones (hereinafter Jones #1)--that is, "Oriental" Jones -- and thoughts of both Jones #1 and Jones #2 prompted your suggested "Okkident" Dalrymple.
I suggest a slight addition so that homoeoteleuton may secure the intended comical echo.
"Oriental" Jones. And "Okkidental" Dalrymple.
You heard right. Okkident.
I thought I'd misheard okkident, so rewound a couple of times. I then wondered if it was an academic or possibly Anglo-Indian variant, checked all my dictionaries and the bible of received pronunciation, Everyman's English Pronouncing Dictionary by the greatest-ever English phonetician, Daniel Jones. Nowhere is okkident mentioned.
Let Dalrymple henceforth be known as Okkident Dalrymple
