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.
One example is below.
Q: How are i.e. and e.g. pronounced?
A: i.e. stands for id est (Latin), which means 'that is'. You use it to link in a deeper explanation about something. Pronounce it 'eye - ee'. e.g. stands for exempli gratia (also Latin), which means 'for example'. You use it to link in an example of a more generic term. Pronounce it 'ee - jee'
Rationale: Perfect answer because it's consistent with context uses required information from the question to provide the detailed answer with an example.
Q: But I am unsure, if I should write 'on' or 'at'. May anybody help me with that?.
A:
'At url' would be the idiomatic way to say this. For these sorts of questions google ngram is your friend. There you see that the usage of 'at' occurs and 'on' does not. One of the commenters is correct though, when you are talking about a web site by name rather than by url you can say either 'at StackOverflow' or 'on StackOverflow' but the latter is more common. Again, using 'cnn.com' as an example, google ngram votes clearly for 'on' but certainly allows for 'at'.
