Who invented profanity?

Fashion decides which words are okay, which words are sacred and which words are profane.  Usually driven by self-appointed arbiters of "decency".  It's actually an interesting subject if you dig into it a bit.

If you use profanity enough, it starts to become a habit, and they just slip without you even meaning to say so - I know because I occasionally finding myself cursing in rather inappropriate situations.\n\nAlthough I'm not a fan of overused profanity, it can sometimes be a very good way of expressing a tremendous amount of anger in a clear, succinct way that doesn't involve either going off on a 20-minute-rant or throwing anything.

Christopher Latham Sholes and his colleagues, Carlos Glidden and Samuel Soulé, invented the first practical typewriting machine in 1866.\n\nThe type-bar system and the universal keyboard were the machine’s novelty, but the keys jammed easily. To solve the jamming problem, another business associate, James Densmore, suggested splitting up keys for letters commonly used together to slow down typing. This became today’s standard "QWERTY" keyboard.

Unfortunately profanity is becoming used more and more. It is a "sign of the times" so to speak. Bubbles2006 had probably a good solution, ask the person to quit saying profanities around you. But this can lead to the person doing it even more to aggravate you. Although I don't care for it I have learned to ignore it and let the person speak as they wish. We cannot change them they must do the changing on their own.\n\nOne very intelligent person once told me, "Profanity is used by those whom lack the intelligence to communicate in any other way." I have often though of that statement when I am around someone who uses gross and frequent profanity.

The application of the word to human intercourse dates at least as far back as Proto-Germanic times, about 2500 years ago.  The form was *fukan "to have intercourse".  It was not vulgar originally.  Indeed, it started life as a euphemism for another word (perhaps lost in time).  The original meaning in Proto-Indo-European (about 6000 years ago) of *pug- was "to strike" (*pug- is the ancestor word for *fukan).

This does not exactly answer your question, but Shakespeare made up many of the words in his plays that have become common words today.  I can't think of one right off, but we had a big discussion about it in my upper division college English class.  There are a lot of words that we just assume have always been around, but in reality Shakespeare made them up.

It's known as elite-speak, or L337 $p34k. It originated in communities of computer gamers/hackers when they wanted to codify what they had to say. It's quite commonly used online these days, but I find it mightily irritating!\n\nThere's a couple of pages on leet for you to peruse below, and an ever-so-helpful leet translator that I just stumbled upon! Good luck!\n\nCrazy kids...

Since the earliest moments of modern human language 100,000 years ago, there were things which people feared--death and the spirit world. Linked to this were processes which were not completely understood--conception (including the procreative act) and the inner workings of the human body. As a response to that fear or ignorance certain groups of words became taboo, which means that you don't talk about them. Why not talk about them? Because by naming death, you summoned it to you; by talking about reproduction, you risked the life of the unborn; by naming a deceased relative, you summoned their ghost; by talking about a body part used in reproduction, you risked its malfunction; by naming a deity, you called it to you and that was never a good idea.\n\nDeath is a common one. No one says, "My father died". People say, "He passed away", "He went to meet his Maker", "He went to the great golf course in the sky". In fact, we know that there was an Old English word that meant "to die", because the Middle English word is clearly derived from an Old English word, but it was never, ever written down anywhere in all the Old English texts that exist. In some cultures, you never again mention the name of a dead person.\n\nAnother common place for taboo words is in human reproduction. We don't say, "I f**ked her and she got pregnant" in polite company. You say, "We fell in love and she is now eating for two." The same goes for waste elimination processes.\n\nWhen someone says a taboo word, the common reaction is to cringe or shy away from that person. You don't want to bring the wrath of deity down on your head, you don't want death to come, you don't want a woman to miscarry. All these things are common responses to the use of taboo words.\n\n"Cursing" is just an extension of the use of taboo words. In Modern English, there is a certain set of words referring to body waste elimination, the reproductive act, and the body parts used in that act, that are considered wrong to use in polite company. This is just a modern version of the taboo words that have always been with us.\n\nEDIT: And BTW, there is not a single solitary curse word in English that is derived from an acronym. They are all ancient words in English and date back to Proto-Germanic. In fact, 2500 years ago, "f**k" was the POLITE way to talk about intercourse. Then it was the POLITE way to talk about breeding animals. It is only in the last few centuries that it became taboo and not a respectable word to use in formal settings.

There are a couple of possible theories of origin for the term "gibberish". One says that the basis is in the old word "gibber" which is allied to "jabber". However, "gibberish" was in use before the word "gibber", therefore making this a dubious theory. A better explanation says the word comes from Geber, the name of an Arabian alchemist in the 11th century. He invented a strange terminology so that his works could not be understood by others; more importantly, he could not be accused of heresy, which was punishable by death. "Gibberish" in its modern sense was certainly used by 1811.
