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 there a word which has this definition: usage of vulgar or abusive words too often especially while chatting or talking to someone or while giving a speech. What do you call a person who uses abusive words too often without needing to.
Example Output: Two adjectives come to my mind for a person who uses excessive foul language: 1) crass having or showing no understanding of what is proper or acceptable; rude and insensitive 2) vulgar (as you used in the title of your own question) not having or showing good manners, good taste, or politeness. Both of these suggestions are more reflective of the person's demeanor or temperament than the cursing itself, but I think they could be more colorful (pun intended) alternatives. I hope this is helpful to you!

Example Input: Do the English have an ancient (obsolete) verb for the action of the book opening? For example, in Russian we say otkrit' (open the book), but in the Old slavonic the verb razognuti (to unbend the book) was used.
Example Output: This is a very interesting question. There may not be an old word in English that does what you describe, but it is important to note that the English word 'open' relative to a book meant something different in earlier times. To open a book now usually means to part or spread the cover and the pages into a position so you can read the pages contained in the book. However, books used to be made by folding sheets of paper larger than the page size and they would be sold without trimming the edges, so when you got your new book, it would be 'unopened' meaning that you couldn't turn the pages. You had to 'open' the book with a dull knife (like a letter opener) by ripping along the folds. (This is why some books have ragged edges of the text block, to evoke the memory of those ripped page edges.) The OED has e. transitive. To cut open the leaves of (a book) when they have been left joined along an edge during the making; to cut open (the leaves) of such a book. You will find old books described (by knowledgable book dealers) as 'unopened'. This correctly means that the folded sheets are un-ripped; it doesn't mean that no-one has ever spread the covers and looked inside.

Example Input: Possible Duplicate: Which is the proper spelling: 'disfunction' or 'dysfunction'? What's the rationale behind dysfunctional being spelled dys- and not dis-?.
Example Output:
From WordReference.com on Dysfunction vs. Disfunction: dys- is a Greek prefix meaning 'bad', 'abnormal', 'difficult', or 'impaired'. dis- is a Latin prefix with none of the above meanings. dys- has the right meaning, but function is a Latin word. Hence the confusion. Latin dis- can mean 'lack of', 'not', 'opposite of', 'away from'. This all explains why something dys-functional has a bad or abnormal function, rather than a lack of function that dis-functional implies.
