    looks like nobody agrees - how does the creator say it, thats what they had to do with linux to get everyone to shut up about it. But, the originator of the word is probably long since dead... so can we make up our own rules then? Commented Jul 7, 2015 at 23:42

There are two possible pronunciations, one to rhyme with two pull (/tupəl/) and the other with supple (/tʌpəl/).

Take your pick. There will always be someone to agree with you... violently :)

    Just being picky here, but "two pull" and "tuple" are not perfect rhymes, since "pull" is [pʊl] and the "ple" in "tuple" is [pəl].

    In dialects of English that have not experienced yod dropping (and still make a distinction between the words dew and do, such as RP), you will also hear /tjupəl/, which is how I would pronounce the word. I have often (in London) heard /tupəl/, though I have never heard /tʌpəl/. (I'm with tchrist on that one ;o) Commented Feb 25, 2012 at 20:53

    I've always pronounced it two-ple. In Python programming circles you'll find proponents of both forms - and usually we're pretty accepting of each other's craziness ;) Commented Apr 30, 2012 at 14:19

It should be pronounced to rhyme with quintuple, sextuple, octuple etc, since these are its origins.

    This is how I've heard it pronounced in the USA (except that I would leave "quadruple" off the list since the "u" there is long). This one may be subject to some regional differences, given @Ham and Bacon's answer.

    @JeffSahol: You're right that there are regional differences: for example the "u" is long in "quintuple", "sextuple" is long in British English. Saying it's "like quintuple" is about right, because although in my experience there's quite a lot of variation in how people say that word, exactly the same variation occurs with "tuple" :-)

    So next question. What is the correct pronunciation of those three words! Commented Jun 5, 2014 at 21:54
  • 4
    Well, sure, but then you are purposefully excluding quadruple (quadroople, not quadrupple), which conveniently breaks the mold. I think the more complete answer here lies in the phonetics of the prefix of the word. When the prefix (ends in?) a soft/non-consonant sound (or non-existent), the 'u' should go long vs short. ie: 'qua' is different from 'quin', 'sex', 'sept, 'oct'. Now, if Tuple were instead Tuplet, I would go with the 'upplet' :-o! Commented Aug 25, 2016 at 16:50

    Please expand your answer. How do you pronounce quintuple? Bear in mind that not everybody around is a native English speaker. Commented Sep 27, 2017 at 12:56

I don't use either of the pronunciations Benjol mentioned. I say /tjupl/, the first syllable rhyming with "stew".

I suspect that Benjol has a dialect in which "dew" and "do" are homonyms, but they aren't for me or most British speakers.

    Really? I've never heard anyone in England say "tewple" - it's always "toople".

When I first heard of tuple in C.J. Date’s book An Introduction to Database Systems, he goes to the trouble of explaining that it is pronounced like couple. That was in an early edition around 1983.

    I'm not entirely convinced that Date has any right to pontificate, but +1 for actually providing some evidence, rather than 'this is what I do'. Commented Jun 23, 2013 at 20:15

I am a British speaker.

I pronounce Dew and Do differently (dew - stew - chew / do - too - who).

But tuple/quintuple/quintuplets I pronounce with 'up', not 'oop' (tuple - supple).

So do any other British speakers I know.

  • 4
    The "dew"/"do" distinction you are referring to is because UK English allows the /j/ onglide to occur after coronal consonants, /t,d,s,z/ and so on. Although both AmE and BrE can distinguish "fool" /ful/ and "fuel" /fjul/, AmE treats both "dew" /dju/ and "do" /du/ as /du/.

    Yes, @kosmonaut, that is quite right. I used the other words to try to provide 'sounds like' examples for my own pronunciation in the absence of IPA symbols. (I've seen them used on here but I don't know how people do it)

From dictionary.com:

tjʊp ə l, ˈtʌp ə l)

So, the actual pronunciation is actually either "tew-pel" or "tu-" as in "but".

    Isn't /ˈtʌpəl/ more like "tupple" than "tew-pel" or "too-pel"?

    /tjʊp ə l/ is yet another pronunciation, that nobody else has mentioned. I say /tjup ə l/ with a tense /u/ not a lax /ʊ/

    @ColinFine I would say that /tjʊpəl/ is almost certainly a typo. Stressed /jʊ/ is not a phonotactically valid sequence in any type of English I’m familiar with, except just possibly as a variant of /yud yəd/ for ‹you’d› (and there it’s probably just the result of allophonic lengthening of the schwa before a voiced plosive, as is regular). Commented Jun 5, 2014 at 20:33

Tuple can be pronounced as “tewple”/"toople” or “tupple”

Broadly speaking, there are two main pronunciations of tuple: “tewple” and “tupple”. Neither one is incorrect, so there is no single correct way to pronounce this word. As Ed Guiness says in his answer, it is derived from the end of quintuple, sextuple, octuple etc. and the same variation exists in the pronunciation of these words.

By “tupple” I mean /tʌpəl/, a pronunciation which is more or less the same all mainstream accents of English.

By “tewple” I mean a pronunciation that starts the same way as “Tuesday”, a word whose pronunciation varies by accent:

  • /tjuːpəl/ “tyoople” like /tjuːz/ ("tyooz")-day in accents that maintain word-initial /tj/ clusters
  • /tʃuːpəl/“chewple” like /tʃuːz/ ("choose")-day in accents that change word-initial /tj/ to /tʃ/
  • /tuːpəl/ “toople” like /tuːz/ ("tooz")-day in accents that drop /j/ after word-initial /t/.

However, one commenter on this page, Marcin, has indicated that he uses and is used to hearing "toople" even in a British English context (in England), and there are three upvotes for his comment.

If a non-negligible portion of British English speakers pronounce tuple as "toople", with a different start from the word tutor "tyooter/chooter", an explanation could be influence from hearing American English speakers pronounce the word.

It's unclear to me how widespread the pronunciation with /tu/ "too" might be for speakers that otherwise don't drop the sound /j/ after /t/ in words spelled with tu-. A subsequent comment by Scott Earle, also currently with three upvotes, says "I'm British and also rhyme it with "tulip" and "tutor" (Aug 6, 2014).

“Tewple” is more regular, going from the spelling

The “tewple” pronunciation is more regular. (This doesn’t necessarily mean it is more correct, but some people might think it’s relevant.) In words of Latin origin, the letter “u” usually corresponds to the “long u” sound when it comes before a single consonant letter and a vowel letter, or before a consonant letter followed by “r” or “l” and then a vowel letter (e.g. nucleus, nutrient, duplex, Jupiter).

However, tuple = “tupple” is not an unprecedented sound-spelling correspondence

There are a small number of exceptions to this rule about the pronunciation of "u" before a single consonant followed by a vowel letter or the letter "r" or "l", so the pronunciation “tupple”, while less regular than “tewple”, does have some precedent.

For some words, an exceptional pronunciation with “short u” is only used by some speakers. Some of these exceptional pronunciations have been criticized by prescriptivists. (See the entry for “culinary” in “The Big Book of Beastly Mispronunciations”, by Charles Harrington Elster, who seems to view the pronunciation with /ʌ/ with a kind of resigned acceptance. The two other words I know of that are variable between “long u” and “short u” like this are jugular and truculent, although I haven't come across any prescriptive references that talk about them).

But there are other words like this where “short u” is the only possible vowel, rather than an optional variant. These mainly came into English through French (ducat, punish, public, publish, study) although there are also Latinate words taken from French that regularly have “long u” (such as soluble, voluble; the quality of the actual vowel in these words may be reduced to /ʊ/ or /ə/ since it's in an unstressed syllable, but the glide /j/ preceding the vowel makes it clear that it is underlyingly “long u”).

According to the Oxford English Dictionary, the word quintuple did come into English from French, so I see no clear etymological basis for considering it incorrect to pronounce it with either the vowel of “soluble” or of “public”.

“Tupple” is probably aided by analogy with single, double, triple

One important factor that has probably influenced the pronunciation of this word is analogy. The first British pronunciations given by the Oxford English Dictionary for quadruple, quintuple, sextuple actually have the stress on the first syllable. However, for American English it shows second-syllable stress. This probably developed by analogy with the stress pattern of the words single, double, triple, which all have penultimate stress. Another example of analogy among this set of words is the use of the -et suffix originally found in doublet (a word taken from French) to form triplet, quadruplet, quintuplet etc.

Single, double, triple all have short vowels, and this probably contributed to the use of a short vowel in quintuple etc. (I don’t know why the vowel of quadruple has apparently been immune to this influence.)

    If "tupple" really is a correct pronunciation, I need to stop laughing whenever I hear people say it. Commented Dec 31, 2018 at 22:35

I was a little surprised to hear two people who sounded like Brits (Tim Isted and Dave Addey) both saying "tupple" in the "Introduction to Swift" session (402) at Apple's WWDC 2014. (Unfortunately, this is not public.) Like Colin Fine, above, I've always said /tjuple/, and thought that was standard in the UK. Then again, Tim and Dave work for Apple, so maybe they've adopted a company standard.

On "tjuple" vs. "toople": my guess is that this is the same UK vs. US variation as we see with "stew".

Here is a list of many online dictionaries out there that can help you with this. I suggest you click on the links and listen to the pronunciations yourself, when available.

Cambridge Dictionary


noun [ C ] /ˈtuː.pl/ /ˈtjuːpəl/ /ˈtuːpəl/

Oxford Dictionary



Merriam Webster says

Origin and Etymology of -tuple

quintuple, sextuple

Now looking at one of them, say quintuple on the same dictionary, we get


\kwin-ˈtü-pəl, -ˈtyü-, -ˈtə-; ˈkwin-tə-\

The Free Dictionary: Lists two different pronunciations


(to͞o′pəl, tŭp′əl)
(ˈtjʊpəl; ˈtʌpəl)



ˈtjʊpəl , ˈtʌpəl



/ˈtjʊpəl; ˈtʌpəl/



/ˈtjʊpəl; ˈtʌpəl/

My conclusion:

I prefer the first three dictionaries listed, naturally, and sometimes Collins. The first three consistently say that, pronunciationg of "tu" part of tuple is as in "stew" or "tool", but not rhyming with "but". More importantly, as said in Merriam-Webster, and also as did Ed Guiness in his answer, "tuple" should rhyme with its origins- quintuple, sextuple, etc.


Should be pronounced "too'pəl" the way the dear Loord intended, unless you're joost being stoobborn.
