[EX Q]: I want to ask whether I can use the word 'Fuck' in a formal context. Apparently, the word dates back to the early 16th century, so it shouldn't be considered slang (although, it is misused as slang for other reasons), but regardless of its vulgarity, could I use it in a formal context with its original definition? I imagine that people will be surprised, but when realizing in what context I am using it in, then it will be more understandable and acceptable to use it. Firstly, I do not even know the definition of the word due to its vastness in meaning, I always thought it was an exclamation-like word meaning nothing (for it to mean sexual activities is a slang definition, is that not correct?), but used purely for emphasis. What does it first and foremost mean in its original/accurate and/or formal definition? I also know of another definition of the word 'Fuck,' which is 'I will fuck you' as in 'I will defeat you' (in context of fighting or combat), is that a formal definition as well? I mainly ask for this, because I need to use the word in this context, specifically and especially. Also, side question, is it possible not to always make it a vulgar word? Thanks in advance.
[EX A]: Let's just go ahead and say, no. It's questionable to use expletives here, so... unless you're writing a dissertation on the usage of the word in question, again: no. You shouldn't use any word you don't know the definition of, but here at Stack Exchange you may use them to talk about them. They are permissible when they are the context.

[EX Q]: I see a lot of times when something is a politically-oriented scandal that the suffix gate is added to the end of the word the scandal revolves around. Examples include: Watergate Weinergate Valijagate (Spanish for 'suitcase-gate') I believe that it originated during the Watergate scandal, but I don't know why the suffix gate was perpetuated to other scandals. Is there a name for this literary mechanism of using part of previously popularized term to elicit a comparison or similar connotation?.
[EX A]: This is a great example of a back-formation: a word is treated as if it were composed of prefixes or suffixes, then taken apart (incorrectly) and remixed to form new words. Another famous example is cheeseburger. The burger suffix is incorrectly taken from hamburger, which is a dish from Hamburg, not a burger made from ham. Watergate was a big enough scandal, and sounds enough like it's composed of Water and gate, that the suffix has been back-formed into plenty of other scandal names.

[EX Q]: What would be the opposite of 'sexy clothes', as in 'clothes that hide sexual bits' ? Like for a woman, a top that would hide and make her breasts much less pronounced? Thanks in advance.
[EX A]:
OED Modest (of a woman) dressing or behaving so as to avoid impropriety or indecency, especially to avoid attracting sexual attention. 'the modest women wear long-sleeved dresses and all but cover their faces' I think modest clothing conveys the meaning you're looking for.
