why the two X in the word XEROX is pronounced differenrently that is first one as J and last one as X ?

Answer 1

It isn't. The first one is kind of like a zy - you pronounce it zyer-ocks

Answer 2

Xerox was originally the Haloid company which bought the work of Chester Carlson. Carlson initially called the process electrophotograpy but Carlson and Haloid decided that word was too cumbersome and with the help of an OSU professor coined the word Xerography (from Greek: Dry + Writing).

In 1949, they produced the first office copier and called it XeroX. And in 1961 They changed the company name from Haloid Xerox to just Xerox and listed themselves on the stock exchange as XRX.

As to the pronunciation: mostly what doktordbel said already that an X at the beginning of a work is pronounced with a Z sound and in the middle or end with an X sound. But that is the history of how they got the word.

Answer 3

In American English, people tend to avoid pronouncing certain combinations of consonants at the beginning of the word, and this often applies to pairs of which the second consonant is an "s": e.g. in "psychology", the "ps" is pronounced as "s/z", whereas "ps" in the middle/end of a word is pronounced in full, e.g. epilepsy. The reason is that it's hard to pronounce certain combinations of consonants without having a vowel first to "prepare" yourself to let it roll... the Spanish do the same by pronouncing "student" as "estudent".

Since the "x" is phonetically equivalent to "ks", the "k" sound is omitted at the beginning but pronounced at the end of the word.

Answer 4

X at the start of a word is pronounced like z, ex. xylophone. Who knows why. When it is in the middle or end it sounds like x ex. mexico, Texas.
