Having a doctorate from both Cambridge and Oxford makes Mabberley what Ghil'ad Zuckermann calls an "Oxbridge paradox": Mabberley belongs to the rare group of people who hold a "pair o' docs" (sounding like "paradox" but meaning "two doctorates"), a D.Phil. (Oxon.) and a PhD (Cantab.), from both Oxford and Cambridge universities (commonly abbreviated as Oxbridge) - see Biography.
