Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

Example Input: Is it ok to talk about 'personal PCs', in the sense of distinguishing it from a work PC? Or would it be regarded as a case of RAS Syndrome?.
Example Output: Though the word personal is repeated in the expansion 'personal personal computer', the two repetitions use different meanings of the same word. The first personal means 'owned or used by a specific single person' (definition 1 here), while the second indicates 'designed to be used by a single person' (definition 2 here, again). Both instances are required to convey the full idea and thus are not redundant. Consider the following examples spelled out in full: Personal PC: personal personal computer, (the usual case of a personal computer owned by a person) personal mainframe computer (I have a Cray in my bedroom), Public PC: public personal computer (a PC that is installed in a kiosk usable by anybody)

Example Input: I'm having a serious argument with a friend on the status of the word 'suck' when I used it about him by saying 'You suck!' because he missed a train. We are both non-native English speakers. He claimed that I used it as a foul or slang term. I vehemently disagreed with him about it. I told him that the word 'suck' can be used to describe something inefficient or not good enough as well like it is used in the example 'Samsung mobile sucks'. Am I right to describe the use of the word 'suck' in such context?.
Example Output: Yes, you can use the word in the way that you have described, but it's considered more harsh than polite, and it has somewhat vulgar overtones. How it's regarded or received might be generational. I typed is suck vulgar? on Google, and found mixed responses. Feel free to do the same if you want diverse opinions on the matter. I thought this excerpt from a blog post, though, was worth pasting into an answer here: Some may not believe this, but suck as in 'Man, this class sucks' was also in the raw obscenity category when I was a teenager. It was used plenty in the school hallways but not in front of your teacher and never in front of your mother. I remember some agitation by certain culturally-advanced youngsters who tried to railroad their elders into accepting sucks as a safe and harmless substitute for stinks. The elders weren't having any of it, last I checked, but the liberalizing linguists seem to have carried the day. I have always assumedrightly or wrongly, I do not know that the word was originally intended to carry sexual overtones, which was the reason for its suppression. Today, the sexual overtones are either forgotten or are now acceptable in mixed company. I'm not sure which explanation disturbs me more. I think you and your friend are unlikely to come up with an agreed-upon viewpoint, because you're both right in a way. Feel free to use it on message boards and the like when you want to express a negative opinion, but realize you'll risk sounding a bit uncouth to some when you do. Then again, maybe I'm just showing my age here. As a footnote, you might want to check out our sister site, English Language Learners.

Example Input: I'm a little bit confused with the following phrase. I was reading an article about concurrency in Java and there was a sentence saying: It is worth noting that both unlockRead() and unlockWrite() calls notifyAll() rather than notify(). This phrase seemed quite strange to me. What does it mean?.
Example Output:
'It is worth noting that' simply means 'here's something, which you should remember:' or 'here's something you should pay attention to:' or 'here's something that is worth reading and remembering:' It's that simple. Regarding (1), there is no connection at all to 'apropos' or 'besides...' Regarding (2), it always means exactly the same thing. It simply means 'Here's an interesting point:' (There is utterly no connection in any way to 'useless' or 'costs nothing'.) It is worth noting that, the ELL site exists for basic questions about the meanings of phrases.
