Perhaps one of the most interesting and colorful words in the English language is the word "Fuck.
" It is the one magical word, which, just by it's sound describes pain, pleasure, love, and hate.
In language, "Fuck" falls into many grammatical categories. It can be used as a verb, both transitive (John fucked Mary) and intransitive (Mary was fucked by John).
It can be an active verb (Mary doesn't really give a fuck); or an adverb (Mary is really fucking interested in John); and as a noun, (Mary is a terrific fuck).
It can be used as an adjective (Mary is fucking beautiful). As you see, there are very few words with the versatility of "Fuck."
