I always get confused about:

  • Is it true?
  • Does it true?

Where and when should I use one or the other? In other words, when should I pose a question using is and when should I pose it using does?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

sємsєм, is "does it true?" the way to say it in your language? – Tristan Jun 13 '13 at 16:26
@Tristan In my native language Arabic verb to do means, mainly, to make something. The typical example: to do homework. Also in my native language asking, or talking about, for being something we use undeclared verb to be. In other words, in Arabic there is no asking without a tool of ask, like what, how, where, etc. However, one may, rarely, ask without tools but it will be depend on the style of speaking. – sємsєм Jun 13 '13 at 21:10
I hope that in questions closed because it is too basic and in the close message you regard a link to one, or more, of the standard internet reference source designed specifically to find that type of information. Thanks! – sємsєм Jul 1 '13 at 5:17

You'll use "Does it x" when "x" is a verb (action word). Use "is" otherwise.

...which is to say the one should never say 'Does it true?'. – Mitch Jun 5 '13 at 0:26

"Is it true?" is an appropriate rejoinder to the statement "His testimony is very convincing!" An appropriate response would be, "[But] is it true?"

"Does it true" is not ever used in English. The following sentence, is, however:

"Does his testimony ring true?"

In other words, does the person's testimony sound true. The word "ring" suggests a bell that rings clearly and distinctly; it rings true. Truth can ring true. By the same token, however, it can also ring untrue or false. ("To ring false" is not a saying in American English, by the way.)

Some people are better liars than others, so one needs to be careful when trying to "read" people.

"Does it true ..." is just an incorrect use of the phrase "Is it true ..." and seems to be popular in slang/ teen lingo.

Does it true is wrong, ungrammatical in formal writing and does not mean 'is it true'.


  • I heard that the [separated] memory space will be put into the coming Java SE 8, does it true?

  • My dictionary says me that "throw off the scent/track" has an identical meaning. So, does it true or the answer with the "scene" is not correct?

  • … does it true that validome (xhtml) is more strict (up to date) than w3c x/html validation?
