How do you pronounce "GUID?" Is it one syllable or two?

  • 14
    Four syllables. Feb 4, 2011 at 5:45
  • I personally pronounce it in 4 syllables, but most of people pronounce it in one syllable.

  • Perhaps this should be asked over at programmers.se. After all, they are the ones who say it. Feb 22, 2012 at 22:23

    @FumbleFingers: oh make no mistake, it did get asked on SO (closed), and then on Programmers (probably deleted, this is the only one I can find right now, but it's closed as well), and then who knows where else.

    @RegDwight: Oh dear! I suppose now we'll get bombarded with more of the same re Linux, GUI, SQL, etc. All effectively "unanswerable", because different people pronounce them differently. And if anyone tells me again we should pronounce Linux in a Linus Torvalds accent, I shall scream! Feb 22, 2012 at 22:43

Wikipedia's article aside, I think it is more common in the IT industry to hear GUID pronounced as:

GOO-id (/ˈguːɪd/)

with a hard G sound (at least in Australia, the UK and Canada).

    In a wide variety of IT contexts all around the US this is by far the most popular pronunciation I've heard. Gee yoo eye dee is the next most, and the couple of times I've heard gwid everyone turned to stare and try to figure out what the speaker was saying. Aug 26, 2011 at 21:34

    I suspect the two-syllable pronunciation is common due to the two-syllable pronunciation of GUI, goo-ee. Goo-ee, goo-id, goo-ee, goo-id. Aug 30, 2011 at 7:50
  • I - and all of my IT colleagues - pronounce it like this. Any other version would be most odd. Feb 22, 2012 at 21:42
  • I really, really, really hope and wish the guy I used to work with who always says gwid comes here... It's nonsense!

  • All the way through college it was pronounced "gwid" by professors and students. So we adopted it and when I got my first job everyone there said it that way too. It wasn't until my second job that I even learned of the GOO-id pronunciation.

I go with the 1-syllable version (gwid) that rhymes with squid and liquid and that matches the pronunciation of "languid" http://dictionary.reference.com/browse/languid.

    +1 I eventually settle on this if I have to say it enough times to one person in one day. I normally start with G-U-I-D, but I drop to Goo-Id after a while (instantly if the other person says that first). But by late afternoon if I'm still talking about them, they're definitely "Gwids". I know it's only three syllables saved, but "life's too short" and all that! Feb 22, 2012 at 22:49

According to Wikipedia:

pronounced /ˈɡuːɪd/ or the preferred pronunciation /ˈɡwɪd/

So, the single-syllable pronunciation is preferred.

I'll probably continue to spell it out when I come across it despite that fact. :)

    I don't really trust Wikipedia here, who prefers it? I was always more familiar with goo-id and it's also in the top-voted relevant answer over on Stack Overflow

    Initially tempted to vote down because I completely disagree, but won't because the source is listed. In my not inconsiderable experience, it is either spelt out our G-U-I-D, or is pronounce goo-id. My main experience is in the UK, but I've seen dozens of American presentations/seminars/etc, and in each case, these two options have been prevailent. I have never heard it pronounced gwid.

    Interestingly, the "preferred pronunciation" comment was only added to the Wikipedia article two weeks ago, with no citation. I'm inclined to treat it as a bit suspect.

I've heard several pronunciations of this. The frequency I've heard (in London, GB) would be:

  1. /ˈɡuːɪd/ (two syllables)
  2. /ˈɡwɪd/ (one syllable; my preference)
  3. /ˌdʒiː juː ˈaɪ diː/ (four syllables)
  4. /ˌɡu(w)ɪ.ˈdiː/ (three syllables: gooey-dee)
  • I've heard it pronounced with in the same four ways in Michigan, US, and Arizona, US. Popularity IMX seems to be 3., 2., 1., 4.

I pronounce it with four syllables, as the alternatives sound a little weird to me.

    I try not to pronounce it at all.

You can pronounce it as four syllables (/ˌdʒi ju ˈaɪ di/), or like a single syllable (/ˈɡwɪd/).

I don't know if there is a preference between the two pronunciations, but I would expect that the second pronunciation will become the most used one.

  • /ˈlaŋɡwɪd/ is the pronunciation of languid given from the Oxford Dictionary of English, so it should definitively be /ɡwɪd/.

  • (In American English, it would be /ˈlæŋɡwəd/, basing on the NOAD.)

  • Hmm. I guess it might be. I'm an American English speaker and I identify the vowel in words like this with /ɪ/, but it doesn't really contrast with /ə/ for me. Sorry, I keep on making comments but I just noticed one more thing! I think the normal stress on acronyms is actually secondary stress on the first syllable (actually, maybe even on all the syllables) and primary stress on the last syllable. So I would say /ˌdʒi.ju.aɪ ˈdi/, definitely not /ˌdʒi ju ˈaɪ di/.

I like the version that rhymes with squid (hey, I'm a Southerner), but I understand that it can rub people the wrong way like Bush's pronunciation of nuclear. It seems to me that this may be based both on the linguistic region as well as the technology used. I first heard about this back in the early 1990s from a Microsoft class and they used the squid-guid.


All versions sound a little weird. I hear people say "in using the global ID"; "referencing the globally unique ID" more than I hear G-U-I-D; or guid (squid); or goo-id.

Unfortunately (or fortunately) there doesn't seem to be a consensus.


The purpose of shortening something to an acronym is for ease-of-use. It seems logical that it's easier to say a one-syllable word (squid/guid) than endure the agony of having to pronounce a distinct two syllable (fluid/guid). Since GUIDs are in the realm of programming and programming is all about logic, it seems the most logical pronunciation is the single-syllable squid/guid.

    In the same way as how the USA is pronounce (y)oo-sa, the UK is uhk, an Operating System is oss, the Internet Protocol is ipp, and Active Server Pages are a type of tree? No. That's not how language works. It may seem the most logical, but it remains by far the least common in actual usage. Jun 25, 2015 at 22:40

On the off-chance there is any interest in the actual traditional word "guid" of Scots English, the pronunciations /ɡyd, ɡɪd/ are given in this dictionary entry: guid, though to me, judging from the pronunciation recorded here, it sounds like [ɡɨd] or [ɡɯd].
