Here are IPA and phonetic pronunciations with sources (for ones I could find):

And here are opinions on ones I couldn't find a source for, or have opinions on:

  • wav: Rhymes with "wave", not "have"

  • cache: /kæ?/ - Rhymes with "cash", not "ay-she" (with a long-a sound like face or Anne Heche)


GIF: Officially jiff, but everyone pronounces the G as in gill.


Daemon-- 'day-mon' and 'demon' are both in common use, but the latter is technically correct if you go by an English dictionary. For fun, see how your system's built-in speech synthesizer says it. (On the Mac, it's 'demon'; TextEdit -> Edit -> Speech -> Start Speaking).


Knuth, From his website:

How do you pronounce your last name?




Wiki (rhymes with hickey)


(no idea)

DEE-mon (like the devil)

(no idea)

WAVE file

GIF (like gift) file


Using IPA:





di.mn? (syllabic n)





wiki - wick-ee

boolean - bool (like fool) + E (long e) + an or un

Knuth - kuh-nooth

daemon - demon

wav file - wave file

gif - I think the question here is if the G makes a g sound or a j sound? I go with the g sound myself.

char - I pronounce it car. It is short for "character", which would suggest the ch be treated like a k sound, however it also might suggest that the a is long making the pronunciation like the word care. With no other vowels I don't think the a should be long, but the ch could still be treated as the k sound.

This symbols pronunciation chart on Coding Horror might be useful to someone looking for the answer to this question


Knuth = Kuh-Nooth with the emphasis on the second syllable

Gif is a soft "G". Some time ago, I had read on a Unisys (patent holder) website that it was a hard G. All other references (including the original developer) say it is "J".

jif (like the peanut butter!)


The real question is the spelling of Boolean, or, should I say, it's abbreviation. It's shortened to "bool" even though it's named after a man named "Boole". You'd think if you wanted to honor him, the least you'd do is spell his name right.....

Another questionable pronunciation is "geocities", which is correctly pronounced "GEE-OH-cities". However, some prefer to say it "GEE-oss-ities". This led me to an idea about the problem of "gif".

"gif" is correctly (according to it's creators) pronounced "jif". Many, however, prefer to say it with a hard G.

My idea is to allow both pronunciations, one as the "correct", and one as the "trendy/ironic" version. "Geocities" can be viewed the same way. The most common example of this is the American department store "Target", where the correct pronunciation is "TAR-get", while the trendy pron. is (pseudo-French) "TAR-zhay"


My native tongue is American English. If I know that a "word" is an acronym, I pronounce it as closely as possible to using the sounds as they appear in the words that are abbreviated. To whatever extent we can claim to be right by appealing to authority, I think English authorities largely agree that this is correct.

Thus, I say GIF (for Graphic Interchange Format) with a hard G as in girdle not giraffe.

The others are less informed:

Dyke-struh K'Newth day-muhn

The others seem to be ubiquitously agreed upon.


In made up names/symbols, I suppose there is no "good" pronunciation, only the one advised by the creator of the name, or the one of general consensus, although there might be schisms, like we see here for Gif. Not being native English doesn't help, some (French) colleagues persist pronouncing char as shar (that's kar for me), and I won't mention log-quatre-j (log4j!). I give here French-style pronunciation, for a change! ;-)

  • boolean - bouléan
  • daemon - démon
  • wav file - ouav
  • gif file - jif
  • PNG file - I pronounce péhenjé, even though I know the official pronounciation is ping
  • wiki - "we key", as in "we keyed your car while you were out"
  • boolean - boo lay uhn, as in "Boooh, Lain! Step out of The Wired, and don't be such a weird show".
  • Dijkstra - "Dike" and the "Stri" part from "Strike", as in "But if we go on a Dike Strike, the flat, flat Netherlands will be flooded".
  • Knuth - with a hard G, then a nu, as in "Saint Iknoothius"
  • daemon - al pa tji know, as in "The Devil's Advocate"
  • wav - in uh fi si ent re pre sen ta shon. Sometimes abbreviated to flack, as in "Free Losless Audio Codec".
  • gif - with a g like in gorge and garage.

Disclaimer: I'm love Lain (she's hot and nerdy). I'm not affiliated with Tokyo TV, The Wired, or Apples' product placement division. But I do have the same weird sense of humor.


I used to pronounce SCSI skizzy for awhile before finally I gave in.


Only youngsters and hipsters pronounce GIF files with a hard "G", they also most likely use the word issues a lot instead of problems and refer to executable code as a "stack". I guess I'm just kind of an old timer or something.
