[EX Q]: Possible Duplicate: Do you use 'a' or 'an' before acronyms? I got the following sentence from the book I'm reading: You can take a database-first approach by first creating a SQL Server database schema. From what I learned, I think it should be 'an SQL Server database schema', not 'a SQL Server database schema'. So which one is correct?.
[EX A]: This depends, I would think, on your pronunciation of SQL. It can be pronounced as 'sequel', or spelled out as 'S-Q-L'. That perhaps doesn't help in written English. A thoroughly scientific survey of Google throws up many more hits for 'an SQL' than 'a SQL'. This is also the form used on that Wikipedia article and elsewhere, such as this Microsoft SQL Server documentation entitled 'Executing an SQL Query'.

[EX Q]: Ok, if I say 'this car is too expensive' or 'this car is very expensive', then I can not express the connotation of 'expensive'. However, if I say 'this car is damn expensive' then I better convey the connotation of 'expensive'. So my question is: What is the English idiom about 'expensive' that expresses the idea that 'It is so expensive that you feel like you got ripped-off and/or overcharged and/or unmeaningfully expensive'? For example, 'damn expensive' could be ok but is there any other term?.
[EX A]: exorbitant is also used for extremely unreasonable prices. An example of using it, quoting the Oxford dictionary: some hotels charge exorbitant rates for phone calls

[EX Q]: Is there a word that describes or denotes a type of conversation in which two speakers speak two different languages. In our country, Pakistan, there are approximately 75 languages, from which Urdu, Punjabi and Sindhi are common, excluding English. So today I found two women speaking two different languages. For example: Speaker 1 has Urdu as their mother tongue. Speaker 2 has Sindhi as their mother tongue. Speaker 1 and 2 spoke their own mother tongue, which are different (Urdu and Sindhi) but both can understand each other's language. I thought that this is known as 'intermingling conversation,' or a 'code switching.' In my opinion, we can't use such words because code-switching refers 'shifting completely to the other language for a word, a phrase or sentence, and then revert back to the base language.' Example sentences: They were in a bus and had [adjective] conversation. They were in a bus and had [noun or noun-phrase for such conversation]. I agree that the question (which is suspected as a duplicate one to this question) is really a duplicate, but its single answer still doesn't satisfy all. In that question, the phrase 'bilingual dialogue' was suggested, which I (and others may) think that this refers to the code switching as well, which I don't want here. Some words confuse the readers which sense do they mean. I would also love to quote the comment of @Lambie regarding the term 'bilingual' over here: 'Bilingual refers to one person. Not two people each of whom has a passive knowledge of the other's language but do not speak it well enough to use it actively.'.
[EX A]:
In his book Talk in Two Languages, Joseph Gafaranga examines, among other things, the patterns of conversation within bilingual families. He calls the pattern described in the OP's question the parallel mode. Here is a screenshot from Google Books of the introduction to his discussion of the parallel mode pattern. So by Gafaranga's terminology the Urdu and Sindhi speakers were conducting a conversation in parallel (language) mode.
