The BBC recently posted an article on “anti-languages,” essentially a type of encryption that allow those who possess the keys to communicate secretly, out loud in public. The piece begins:
“Since at least Tudor times, secret argots have been used in the underworld of prisoners, escaped slaves and criminal gangs as a way of confusing and befuddling the authorities.
“Thieves’ Cant, Polari, and Gobbledygook (yes, it’s a real form of slang) are just a few of the examples from the past – but anti-languages are mercurial beasts that are forever evolving into new and more vibrant forms.”
