In our happy forum, we must often use acronyms or unfamiliar words or phrases when we speak or give explanations.

Here are the ones I've written down:
  • base form: (noun, grammatical term) essentially the infinitive ("to do, to be, to want") without the "to" part. E.g., do, be, want.
  • be-verb: (noun, grammatical term) any of the verbs that are derived from the verb to be. Here are most of the be-verbs: is, are, am, was, were. Remember that be-verbs combined with auxiliary verbs are also be-verbs: has been, have been, will have been, must have been, should have been, etc. and will be, might be, ought to be, could be, can be, etc.
  • Big Book: Quite simply the best book for GRE preparation.
  • btw: (Internet abbreviation) by the way.
  • bump: (vt, Internet slang) to make a meaningless reply to a post so that the original post moves to the top of the forum. For example, if you ask a question, and nobody answers it, you can "bump" your post by adding a meaningless reply such as "Bump!" or "Nobody knows the answer?" Bumping is usually frowned upon, but is acceptable in some cases.
  • imho: (Internet abbreviation) in my humble opinion. Slightly more polite than IMO.
  • imo: (Internet abbreviation) in my opinion.
  • intransitive verb: (grammatical term) A verb that has no object. For more information about intransitive (and transitive) verbs, click here.
  • lol: (Internet abbreviation) laugh out loud. We use this acronym to show that we think that something is very funny.
  • lurker: (cn, Internet slang) a person who visits a forum but never makes any posts in the forum.
  • OG: (acronym) Official Guide. This term is used to refer to the most recent edition of the official GMAT review book.
  • preposition: (grammatical term) A preposition is one of the parts of speech, for example, in, of, for, over, under, like, and because of. All prepositions MUST be followed by nouns; they can never be followed by sentences. When we put a noun after a preposition, we have an "adverbial phrase."

  • SAE: (acronym) Standard American English. This acronym refers to the English commonly spoken in the US. SAE is different from British English (what others might call "English" or "RP").
  • SC: (acronym) subordinating conjuction: a conjunction used to join a subordinate sentence and a main sentence. Check here for more information.
  • transitive verb: (grammatical term) A verb that has one or more objects. For more information about transitive (and intransitive) verbs, click here.
