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: Possible Duplicate: How do I say 'Our meeting is preponed'? A friend of mine asked me this question, and it caught my curiosity. Is there an explicit opposite of the word postpone? As in, do something in advance? Clearly what I just said is functionally equivalent to the answer I am seeking, but I was wondering if there was a single word that is the antonym. More context: Bob was supposed to start work in July, but due to a work visa issue, he had to begin in advance.
Example Output: The most business-speaky option is expedite. Other alternatives include accelerate, hasten, and advance. Technically prepone is in fact the precise antonym, but I honestly wouldn't be caught dead using it.

Example Input: Possible Duplicate: 'Toward' or 'towards'? Which is the correct usage? 'Onwards' or 'Onward' ? For example: I would be free any time Tuesday onward. vs I would be free any time Tuesday onwards. Or is both correct/wrong? The spell checker in my browser says onwards is wrong but I've heard people using it. (p.s: Sorry if this question is redundant. I searched here but couldn't find a related question).
Example Output: Apparently, there is a slight difference, but only in British English: Note: In British English, 'onwards' is an adverb and 'onward' is an adjective. In American English and sometimes in formal British English, 'onward' may also be an adverb. So, depending on where you are, the difference maybe slight. However, they both mean the same thing practically, and most people will understand you if you use either anyways

Example Input: What's the difference between the two? Later the doctors found out that my case was a bit different. Later on the doctors found out that my case was a bit different. Is one more common than the other?.
Example Output:
'later' and 'later on' have the same meaning. Sometimes 'later on' is preferred because it has another, smoother rhythmical flow. You can consider 'later on' as just a variant for 'later'.
