The New Scientist invented a term for such repetitions back in 2001. They called it RAS Syndrome, the RAS standing for Redundant Acronym Syndrome. But the habit is far older than that. In 1668 John Dryden was already referring to "the hoi polloi". Polloi is Greek for people and Hoi is Greek for the, so the hoi polloi means the the people. Indeed, his is the first usage cited by the OED.
Yet, Hoi polloi it must remain because if we dropped the hoi we'd lose the lovely rhyme that distinguishes the base peasantry from the hoity toity.
And if you're American and have been wondering what in blazes a cashpoint is, it's the British term for an ATM machine.

N.B. I am about to try to tinker with the RSS feeds. RSS stands for Really Simple Syndication, however to me it is a mystery on a par with the incarnation or the hard question of consciousness. If a post doesn't show up tomorrow could you inform me in the comments? In fact, does anybody know whether turning on smartfeed in feedburner simply consolidates all the feeds into one, and if so does it disrupt those who have already subscribed? RSVP please.
