The English language is where words go to be tortured and mutilated into unrecognizable shadows of their former selves. It's where Latin, Greek, and Germanic roots are shredded apart and stitched unceremoniously back together with misunderstood snippets of languages snatched from the wreckage of conquest and colonialism. It wreaks merciless havoc upon grammar and spelling. It turns clinical terms into insults and children's tales into filthy euphemisms. With an emphasis on understanding where the foulest words in the English language came from - and the disgusting and hilarious histories behind them - this book demonstrates the true filth of our everyday words. But it is more than just a list of vulgar words and salacious slang. It's a thoughtful analysis of why we deem words as being inappropriate as well as revealing 'good words' that have surprisingly naughty origins.
