Euphemisms like frak have a long history. They’ve been around for as long as people have been getting upset by particular words. But seldom has a euphemism been used as a perfect synonym in 100% of original word’s uses. There is no semantic difference between frak and its forbidden cousin; the only difference is a couple of phonemes. It is not the meaning or the sentiment that is considered offensive and therefore censored, it is the sound of the word. It is not the idea that is banned, but the particular form that idea takes. It makes no frakking sense, but there it is.
You F-word, you N-word, you C-word!
Strange days indeed.
If these constructions have no meanings they would not be words.
Reality, of course, doesn’t give a S-word.
