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.

[EX Q]: I came upon this letter when reading a book, I couldn't find its name on the internet, you can imagine how hard it is to search about it. What is the name of the letter that follows 'sample space'? I know it's not really an English question, but I think this site is best fit for the question than say, the mathematics site.

[EX Q]: Possible Duplicate: Real quick question If you listen real close... Can you swing by real quick... Sentences like the above two are what I often hear in daily life. If I didn't hear them in the real world, I would probably be more ready to say 'If you listen really close...' and 'Can you swing by really quick...'. Is real being used as an adjective in this scenario? If so, is the usage of adj.+ adj. a common practice in English language?.
[EX A]: As intensifiers (words that make an adjective stronger), the adjective form of a word (without the ly) is used very often instead of the adverb form in English. As some of the other answers and comments have remarked, these words are indeed adverbs because they modify adjectives. For example: bloody stupid (U.K.), wicked cold (Boston), dead certain. If you said bloodily stupid in England, wickedly cold in Boston, or deadly certain pretty much anywhere, it would sound real funny. People say real hot but don't often say real true, because real is an intensifier in the first but not the second. (See Google Ngram).

[EX Q]: I was told in a Latin class that the name Christopher has Greek roots that mean 'one who carries Christ'. I assume that the Latin connection here is fero, which is the verb to carry. With that in mind, does the name Jennifer have a similar derivation? If so what would she be carrying?.
[EX A]:
No Jennifer is from From a Cornish form of the Welsh name Gwenhwyfar (see GUINEVERE). This name has only been common outside of Cornwall since the beginning of the 20th century, after it was featured in George Bernard Shaw's play 'The Doctor's Dilemma' (1906). GUINEVERE From the Norman French form of the Welsh name Gwenhwyfar, composed of the elements gwen meaning 'fair, white' and hwyfar meaning 'smooth'. In Arthurian legend she was the beautiful wife of King Arthur who engaged in an adulterous affair with Sir Lancelot. Her betrayal of her husband with Mordred prompted the battle of Camlann, which led to the deaths of both Mordred and Arthur. The Cornish form of this name, Jennifer, has become popular in the English-speaking world.
