Pronunciation of 'cache'

I believe cache is pronounced "kaysh" in Australia

You will find in American dictionaries that it is pronounced cash. Everyone in my office (in Australia) pronounces it kaysh, as do all my friends. I think it's just an Australia pronunciation.

Years ago, there was a perfume called Cashe.
They always pronounced it Cashay.
I hate it when someone on the news calls it Cash.

I first came across the word during a required reading of a Louis L'Amour western in high school in NZ in the 70s. Our French Canadian teacher, who taught both English and French advised us that the correct pronunciation was "cash" - in both languages.
At University in the early 80s my major was Computing, and the correct pronunciation used by all was "cash". At that time we had lecturers from the US, Europe, Australia, and NZ while many had also studied in the US as computing was still in its infancy.
I first heard the pronunciation "kaysh" during a seminar at a local conference circa 1990 by local Macintosh guru John Holley, who somehow had brought this strange pronunciation back from the US where he often frequented.
As a patent attorney and writer of technical documents/specifications I am required to have a reasonably high technical literacy, and deal regularly with experts from multiple disciplines. My observation as a whole is that while most people in the computer hardware industry are expert in their field, they are not my first choice to turn to should I require advice on grammar or pronunciation - somewhat akin to going to your butcher for medical advice.
After being corrected many times by computer industry workers that the correct pronunciation is supposed to by 'kaysh' I investigated the matter in detail. According to authoritative sources, the correct pronunciation is 'cash' - in NZ English, Australian English, US English, Canadian English, British English, European French, and Canadian French. And from my own experience, it was also called 'cash' by the pioneers and early workers in the Computer industry.

Thanks! Your loss is my win. I have to show this to my brother.

Simple phonics rules would suggest the correct pronunciation should be Kaysh.

When a syllable ends in a consonant and has only one vowel, that vowel is short. Examples: "fat, bed, fish, spot, luck".

When a syllable ends in a silent "e", the silent "e" is a signal that the vowel in front of it is long. Examples: "make, gene, kite, rope, use, taste, and baste".

i have always pronounced it as cash,i think thats the best way to do it,i was taught to pronounce it as CASH in my school days,later when i went to a graduate school to complete my IT grad ,there also we pronounced it as CASH.

I'm from Canada, eh. We always pronounced this as cash, eh.

i pronounce it as sashey!
it sounds better than cash doesn't it

If I had a dollar every time... The correct pronunciation of cache is cash. Full stop. End of story.

I have not met one Australian who has pronounced it correctly. Sad.

"cache", pronounced /kaSH/, from French word "cacher" late 18th century.
"cash", pronounced /kaSH/, from Old French word "casse" late 16th century.
(From U.S. Oxford dictionary)

The problem is, the damn English took a good word from the French and abused it for their own use. Then added another word later, abusing it further by pronouncing it exactly the same way as the first word. The American's after their Tea Party have continued the tradition and refused to fix this travesty in having two words with the same pronunciation. (A Honomyn)

On the other side of the Pacific, some of us smarter folks are sick of people giving us dumb looks when we say "it's in the kaSH", and instead pronounce "cache" as " kaySH" to stop the dumb looks and get our message across as quickly and concisely as possible.
As “cache” has been in the “English” dictionary for a while (especially when the other is the older word), perhaps it’s time to ignore how the French pronounce it, and change how we English speaking people pronounce it.
We’ve been changing and abusing foreign words for centuries, what’s a few more in the name of reducing confusion.

The word Cache is a French word meaning HIDE and in English is pronounced CASH

I teach first year computer science at a G08 university in Australia and I have _no_ idea where kaysh comes from. I whack any first year who says "kaysh" within earshot. I'd love to find out where the heck "kaysh" came from and how it gained a life.

In my computing circles in Australia it was always caysh. In my amateur radio circles, it was always geo-cayshing, not geo-cashing. A microfiche is not a microfish. A niche is neesh, not nitch. See a pattern?

I wish you had provided sources, I think the word comes from the French cachè (to hide) and keeps the pronunciation (which is why we keep the accents on the noun rèsumè to avoid confusion with the verb resume)

Therefore I suspect the word is pronounced 'kah-shay' - this was the first article that came up when I wanted to confirm, but does not provide sources or reasons.
