Abbreviations are always a potential source of confusion. Some people might happen to know what OED stands for, and can figure out what NOAD must mean, but others may not be so lucky. Googling for PIE is rather useless even for native speakers, and completely perplexing to non-native ones.

Thus, let us compile (and maintain) a list of common abbreviations.

The following is a list of abbreviations common to all sites of the Stack Exchange network:

  • CWcommunity wiki; a post "owned" by the entire community rather than just the OP
  • EL&U, ELU — short for "English Language and Usage", the name of this site
  • ELLEnglish Language Learners, another Stack Exchange site for questions from those learning English, where answers may be couched in didactic terms more familiar to learners
  • GR or Gen Ref — General Reference, meaning that the question can be easily answered using a dictionary, thesaurus, or other easily-found resources; can be a reason for closing a question
  • HNQHot Network Question on Stack Exchange
  • LMGTFYLet Me Google That For You
  • MSEMeta Stack Exchange, the discussion site for the entire SE network
  • MSOMeta Stack Overflow (also meta.SO), the discussion site associated with SO, which was used for SE network-wide discussions, bugs and feature requests before new Meta Stack Exchange was started
  • NARQ — Not A Real Question, a former close reason on the network for questions which are often overly broad or simply facetious
  • OP — original poster (the author of a given question) or original post
  • OQ — original question, as opposed to follow-up questions, subsequent edits, or tangential discussion
  • OToff-topic
  • POB — primarily opinion-based
  • SEStack Exchange, our growing network of question-and-answer sites on diverse topics from software programming to cooking to photography and gaming
  • SOStack Overflow, the programming question-and-answer site with which it all began
  • TPTB — The Powers That Be, the team that runs all the sites, as opposed to "mere mortals" such as regular users and moderators alike

The following is a list of abbreviations specific to the culture here on EL&U:

  • GAFTAD — Get A Fine Thesaurus; Also Dictionary.
  • IANAL — I Am Not A Linguist [NB In general on SE this stands for I Am Not A Lawyer]

Some conventions:

  • *X
    • for language history and etymologies, it means X is form or word which has no written attestation in the language considered and is therefore reconstructed. This can be either because the language itself is not attested in writing (e.g., all Proto-Germanic words) or because the particular word happens to be unattested, though it is hypothesised to have existed.
    • for current language use, it means the utterance is ungrammatical/wrong (in the variety considered).
  • ?X means that X is a marginally grammatical utterance (could follow the letter of a rule, but sounds a little wrong, or nobody would actually say it that way).
  • /X/ is the phonemic representation of a word in a given variety. X should be in IPA.
  • [X] is the phonetic representation of a word in a given variety. X should be in IPA.

Common abbreviations for parts of speech and syntactic functions:

  • A — adjective
  • adj — adjective
  • AdjP — adjective phrase
  • adv — adverb
  • AdvP — adverb phrase
  • AP — adjective phrase
  • art — article
  • aux — auxiliary verb
  • AuxP — auxiliary verb phrase
  • C — complementizer
  • conj — conjunction
  • D — determiner
  • det — determiner
  • DO — direct object
  • DP — determiner phrase
  • interj — interjection
  • IO — indirect object
  • N — noun
  • neg — negator
  • nom — nominal
  • NP — noun phrase
  • obj — object

    Excellent resource but should be linked/incorporated in the FAQ/about.

  • Personally, I think "MW" should just mean Merriam-Webster, without specification to format or edition. If one wants to specify, one could specify. For instance, if one is referencing Merriam-Webster Online, the abbreviation "MWO" could easily suffice. Commented Aug 23, 2015 at 16:46
  • Shouldn't LMGTFY link instead to the post(s) that deprecate its overuse on SE? Commented May 18, 2016 at 22:34
  • SL&U or SLU is for Spanish Language and Usage Commented May 22, 2016 at 0:19
  • I know it's commonly used, but I'd never use the first term or acronym. It seems separatist to me... 'Why don't I understand this language? It must be nonstandard. However shall I find out? I must google it.' Just disturbing...
