How is slang word become word?

Usage. In 1970 the word ripoff was two words and was considered inner city slang. Forty years later it's one word (usually hyphenated) and has a formal meaning: rip-off - A bad deal; an unfair price or rate; A theft or robbery; A scam; A copy, especially one that is illegal or inferior It obviously had a very specific meaning that did not originally have a word or phrase assigned to it in English, so when the slang version came along it stuck Groovy?

Not so much.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
