Maybe this question is a duplicate, but I'm not finding it in my searches.  There are several acronyms in several websites, such as: MMA, MWE, ...  I visit several sites, but as I visit some of these sites infrequently, I do not know what some people are commenting on.  Is there a glossary of this in the Help Center?

What are the common phrases, words, abbreviations that are used on Stack Overflow, Server Fault, Super User, Meta Stack Overflow, and the other Stack Exchange sites? This is meant to be a very quick overview, not an in-depth tutorial. When considering whether a term ought to be included, please use this test:  New user comes in and posts on day 1. What terminology or jargon are they likely to run into (comments, support, system messages, etc.) that cannot be understood from the context without prior experience with the site (that is, clear only if known). For example: &quot;This is a dupe. Flag a diamond mod to close or migrate to SU.&quot; Huh? Can these instruction be made clear from the glossary? Is it clear for those for whom English is a second language?  Please:  Edit the existing answer Insert relevant links to more detailed information on the term/phrase/abbreviation Add only factual information Keep it very, very brief, terse, and to the point Delete your own comments once they become irrelevant (integrated into the glossary) Use the Edit Summary box to note reasons for your edit, not comments  Please avoid:  Opinion Using abbreviations, terms, and phrases inside a description Unverified information Uncommon terms, abbreviations, phrases Long descriptions Unnecessary detail - link to the relevant FAQ instead Citations or examples of usage Inside jokes that are not common on all of the trilogy () Common Internet jargon (that is, , , , etc.) unless usage here differs significantly  Recurring discussion: While the experiment to keep meta-discussion in the comments is going well (that is, deleting them once consensus is reached) it is clear that some discussions will be recurring, and we'll have to keep a record around so people new to the glossary can understand the consensus already reached. Add a new answer if you believe a new issue is likely to come up repeatedly. For instance, discussion about what terms to include, whether the glossary should be broken up to make linking easier, or formatting issues might be best discussed in new answer/comment posts.

As far as I know, a period is commonly used for an abbreviation (e.g., Feb., Mon., Inc.). But I can also see a slash in these cases: w/, w/o.  Is there any grammar rule for an abbreviation? or is latter case an exception?

What is it called when you use many words to describe the word you want to use?  I know there is a technical word that's used in foreign language acquisition that means using many words to describe a word you don't know.  I'm doing it now, just talking and beating around the bush until someone can tell me the word I'm looking for.

IANAL et al. is usually the start of answers to [legal] questions on any SE site (e.g. ). You usually end up with personal opinions which sound sensible and the accepted answer is often the one closest to the OP's hopes. But it's probably often not correct. I know the situation can be rather complicated and even differ by location, but it would be really helpful if the SE team were providing official lawyers (indicated maybe by using a § in the username, forbidden for everyone else, just like the mod ♦) to provide some orientation that one could actually rely on beyond much doubt...

I'm quite new to League of Legends (LoL) but try to improve through reading guides. All too often I stumble upon abbreviations I am not sure what they mean.  Some of those are:   AD AP ArPen AS bot blue carry CC CDR CS Drag Dive mia mid MM Mp5 MP5pL MPen Proc pull (red/blue/drake) red SR ss top TT IMO

What does it mean and where would I use it?

There is clearly a prefix in names like McDonald, McChrystal, O’Brian, O’Neal.  What does this Mc- and O- prefix signify? It looks like Donald, Chrystal, Brian, Neal are perfectly fine names on their own, so why is there a prefix before it?

I just sent a text to a friend, who didn't understand an acronym I used for a game:      "Ah, I said it in a previous text so thought it was ok to abbreviate   it."   Though, since it was an acronym I had created, could I have used the word 'acronymise/ze' to be more specific?   I'm pretty sure it isn't a (formally used) word, but I wondered, as you often refer to acronyms specifically as acronyms, rather than abbreviations. Can you be more specific with a verb, too?  It sounds too odd to me, so I'm guessing generally no. But I wondered—so perhaps I'm wrong. Or half wrong.

A few questions I've run into lately are somewhat confusing, because they are vaguely asking about client-side operations and tagged with .  This can lead to users posting answers that are web related and not client related, or to situations like the one that , where my editing the question and answering the question became sort of a conflict of interest.  It seems likely, in the two instances of this that I've run into in this week alone, that the OP originally specified  for the question, which would have automatically synonymized to .  The questions are too vague with the latter.  In order to clarify these questions from web-related questions, I've been adding .  In this case, however, because I'd also answered the question I was accused of editing the question to fit my answer.  It could be that the assumptions I made were wrong, though I believe it's highly unlikely and I think that's probably a topic for a different post.  There's also a  complaining about this problem, and it does appear to be causing confusion.  JScript is a flavour of ECMAScript, as is JavaScript, so I can understand the desire to have the synonym, but I think in this case an exception should be made.  Examples:    (Conflicted answers, assuming browser or wsh)  (Comments required OP to clarify)  (First answer assumes browser)

I was always under impression, that acronyms ought to be written all caps. However reading  site very often I see some of the common acronyms written as proper names (first cap). For example "Nato" instead of "NATO".   I know that BBC is quite strict in proper English usage, so what would be the reason behind this?

I've discovered that there are many Stack Exchange sites: , ,  and perhaps others.  What are the differences between these sites, and what is  mainly about?  Where can I find a list of all the Stack sites?

Which is proper/acceptable?  Take for instance this sentence:     We would like to use IBM machines.   Now consider that I needed to fully qualify IBM... How do I make this not read strangely?     We would like to use IBM (International Business Machines) machines.   or      We would like to use International Business Machines (IBM) machines.   (Please note that IBM is not the real acronym but it's similar to what I need to pull off)  EDIT:  I should add that part of my question is that if it's incorrect or less correct to put [Fully qualified name] (Acronym) or [Acronym] (Fully qualified name)

I see this ad sometimes and I would like to know what the acronyms are.

On Stack Exchange sub-sites it seems to be a common practice to refer to other Stack Exchange sites by abbreviating the ".stackexchange.com" part of the domain to simply ".se" (often capitalized), as in "math.SE" or "unix.SE". These aren't actual Stack Exchange domains, but they could be, answering only to GET on the root path and redirecting to the relevant .stackexchange.com URL.  Pros:   Leverages an existing community custom from an abbreviation convention to actual references to the relevant sites. Shortens getting to the main page of a site by 15 characters.   Cons:   Some domains such as unix.se are already in use, which at the very least complicates things. Introduces an inconsistency if .se domains for some important sites cannot be bought.

I remember there was a thread here on English.SE this month where someone explained this, but I can't remember how it was called. An example:     Where have you stolen this product?   This question implies that you've stolen this product, although I don't know for a fact you really did.

On the list of tag synonyms page, the terms "Master" and "Synonym" are used.  This is clear. The "Master" tag is the tag that actually is used on the site and the "Synonym" is the tag that gets changed.    But, on the creation page, the wording is less clear:    Here, we have "Source" and "Target". I'm sure that if someone explained which is which to me, I'd understand it but it isn't instantly clear and so I'm requesting that we use the same wording on this page as on the synonym page.  Even if it were clear, why are we using two different terms for each? This makes little sense.

Are there specific rules / conventions at play when creating demonyms? Or are they merely formed organically over time - the most popular winning out?  There are many suffixes to choose from, but I cannot find concrete guidelines as to which is proper to use in which instance.
