Sign up and fuck
it is uncertain to what extent the word fuck was considered acceptable at the time.
The stem of fuccant is an English word used as Latin: English medieval Latin has many examples of writers using English words when they did not know the Latin word: "workmannus" is an example.
However, there is no clear past lineage or derivation for the Latin word.
These roots, even if cognates, are not the original Indo-European word for to copulate, but Wayland Young argues that they derive from the Indo-European *bug– ("be", "become"), or as causative "create" [see Young, 1964].
In any event, the word fuck has been in use far too long for some of these supposed origins to be possible.
In modern usage, the term fuck and its derivatives (such as fucker and fucking) can be used as a noun, a verb, an adjective, an interjection, or an adverb.
There are many common phrases that employ the word, as well as compounds that incorporate it, such as motherfucker, fuckwit and fucknut.
The word is considered obscene, but is common in many informal and familiar situations.
It is unclear whether the word has always been considered vulgar, or, if not, when it first came to be used to describe (often in an extremely angry, hostile or belligerent manner) unpleasant circumstances or people in an intentionally offensive way, such as in the term motherfucker, one of its more common usages in some parts of the English-speaking world.
