Old Jargon, Slang, and Cant
last update: 17 May 2020
This is a special section devoted to old Jargon, Slang, and Cant.
Jargon is about terminology associated with a special field or area of activity, and as someone once wrote "Incomprehensible jargon is the hallmark of a true profession".
Slang is a vocabulary that in many ways is part of the identity of a group, and as the American poet Carl Sandburg (1878-1967) once wrote "Slang is a language that rolls up its sleeves, spits on its hands and goes to work".
Cant is a kind of jargon that is used as a kind of 'secret language' designed to exclude or mislead people who are outside the group.
Argot is originally a French word that would be translated as slang, but in many ways it's similar to cant, since it's designed to exclude 'outsiders' from a conversation.
Slang can range from the rhyming slang of the East End of London, to Lunfardo, the argot of Buenos Aires, to Cantonese internet slang, and to the Lavender linguistics of LGBT community.
The core text I've used is the 21st edition of the "Universal Etymological English Dictionary" of N. Bailey, published in London in 1675.
The focus on this webpage is more on the collection of old jargon. None of the below sections are designed to be complete or exhaustive, but they collect words that attracted my attention.
I have explicitly avoided some topics such as legal, medical and religious words, as well as specialist terms linked to astronomy and geometry, etc. But I have tried to collect words linked to physics, chemistry, measurements, architecture, …, as well as military, monetary and trade terminology. Also my focus is on words that either no longer exist, or have evolved in their spelling and/of definition. So I have not listed words that existed in 1675 and have remained unchanged until today.
In addition I've tried to both describe the original words in their modern context and provide some examples, etc.
