Gazumped. London Calling's on the case. Sniffs out one of the great London words – gazump! From its East End Yiddish roots to its 1970s rebirth in the city’s cut-throat property market, this is the story of how a market-stall cry for “don’t get swindled!” became the headline-grabbing curse of London homebuyers.

It’s a word that sounds like what it means – half comedy, half cruelty – and it could only have been born in London. Pointer David’s on the scent again, and he’s tracked down a linguistic gem that’s equal parts etymology, history, and sheer London mischief.
