[Q]: Today, I received a folder of Recruiting candidate CVs from one of our HR. In this folder, there is a sub-folder named 'pass'. Question is does this 'pass' mean the CVs inside are OK or not OK? If I want to mean the CVs in the folder that are not OK, what exact word should I use?.
[A]: I have encountered many people using the term 'pass' in recruiting. Each time, the person believed they were making a clear statement. Roughly half of them mean 'I don't like this one, pass' (as one might say when playing cards). The rest mean 'I like this one, please pass him or her to the next round' (as the term is used in quality control). Each group is surprised to learn about the existence of the other. I now insist that recruiting feedback never use the ambiguous term 'pass.' Useful terms to replace it are 'proceed' and 'no hire.' 'Proceed' makes it clear that the candidate is moving to the next round, as opposed to 'hire' which may convey a stronger meaning of 'make an offer now.' Simply using 'yes' and 'no' may suffice in some contexts, such as your example of labeling CVs.

[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.
[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.

[Q]: I've been reading Michael Innes books again (in this case 'From London Far'), and I came across the word gratricidal, in the a passage about a Scottish castle... Castle Moila was famous alike in legend, history, and fiction. To these courts Magnus Barelegs has brought fire; Donald, Lord of the Isles, a traitor's promise; Macleod of Lewis a gratricidal knife. Here had come Prince Charles Edward, thwarted of a throne, and daughters of a hereditary captain had offered him manchets and wine. So what is gratricide? Attempts to find this online are stymied by the spelling being corrected to fratricide.
[A]:
Magnus Barelegs, named in the question, was Magnus Olafsen who ruled in the 11th century. Therefore the 'MacLeod of Lewis' mentioned must be contemporary, or perhaps somewhat later. The Lewis branch of the clan MacLeod, descended from Leod, a son of Olaf the Black, was a notoriously bloodthirsty family, particularly among themselves : The traditional progenitor of the Macleods was Leod, whom tradition made a son of Olaf the Black, King of Mann and the Isles. Tradition gave Leod two sons, Tormod - progenitor of the Macleods of Harris and Dunvegan (Siol Tormoid); and Torquil - progenitor of the Macleods of Lewis (Siol Torcaill). In the 16th and early seventeenth centuries the chiefly line of the Clan Macleod of The Lewes was extinguished due to family infighting. This feuding directly led to the fall of the clan, and loss of its lands to the Clan Mackenzie. The modern line of chiefs of Clan Macleod of The Lewes are represented by the leading family of a cadet branch of the clan - the Macleods of Raasay. ScotWeb Thus the reference is almost certainly a misprint for 'fratricide'. Note : As one of the Johnstones of Annan (Numquam non Paratus - 'never unprepared') whose ancestors were prone to sneak over the border and raid the English, one can make no criticism of other Scottish clans.
