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.

Let me give you an example: How are i.e. and e.g. pronounced?
The answer to this example can be: i.e. stands for id est (Latin), which means 'that is'. You use it to link in a deeper explanation about something.

Here is why: Perfect answer because it's consistent with context uses required information from the question to provide the detailed answer with an example.
