Crime was rampant in the Regency Era, and some people attributed the increase to an upsurge in population, particularly of male youths, boys from 8 to 16 years of age. A committee established to look at crime noted that they believed the increase arose “from more active and general prosecution of petty crimes.”
Petty criminals could be found anywhere, including on the streets, at exhibitions like Madame Tussaud‘s, or even in church and among those that traversed London streets were the cheats, swindlers, and pickpockets. If you were not one of them, you were busy keeping an eye out to avoid them. However, it was not easy to deter or steer clear of them, as they always kept “a sharp look out to entrap the property of the honest part of the community, to take in and cheat the unwary, — to rob and perhaps murder the unprotected, to make prey of the unsuspecting.”
One way the cheats, pickpockets, and swindlers accomplished their goal was using a language not readily familiar to the public. A few of the more interesting words, terms, and phrases they used are provided below:
