For many speakers and learners of English, the word "Oxford" spells authority about language. The second edition of the Oxford Dictionary of English is no exception. Any dictionary which comes from Oxford University Press (whose origins lie in the Middle Ages, the foundation of the university and the dawn of printing) tends to be in a different league from its competitors. Based on the "Oxford English Corpus", language databases, which amount to "hundreds of millions of words of written and spoken English in machine-readable form", this hefty single-volume dictionary has four million words of text. That includes 355,000 words phrases and definitions, 12,000 encyclopaedic entries and 68,000 explanations. The statistics are mind blowing. Like all good dictionaries it's bang up to date. "Greasy spoon", "data smog" and "WMD" are all here, scrupulously glossed. So, of course are wonderful, old, near-obsolete words like "editrice" and "bouffant". Plenty of proper names get in too. Did you know that a "Queensland blue" is a cattle dog with a dark speckled body as opposed to a "Queensland nut" which is another name for the macadamia nut?
