Bert: oh how people have already come to know me on here. But I believe swearing to be a completely legitimate part of language, i do remember a thread that dealt somewhere with this, but i can't be "arsed'(bothered) to look for it. When you have students that are going to live in the UK for any length of time and they will encounter these words so I always want them to be prepared.

The eff-word is a particularly all embracing word that is used as a conjunction,adverb, verb, adjective, noun, phrasal verb and the list goes on. I used to work with a guy who used it in all of the above grammatical senses all of the time, became a bit embarrasing when you went in to a caff for our breakfasts.
