Redundancy of English letter 'x'

 

In continuation with an earlier post:

, I continue regarding redundancy of some English letters.

I want to talk a bit about the English letter 'x'.

When a word starts with the letter 'x', it invariably has the sound of 'z': xylophone, xenophobia, etc. Except in the case where 'x' is hyphenated with another word, the sound is always of 'z': x-ray, x-rated, etc. Even in the case of names of people, or companies, we pronounce it with 'z': Xi Jin, Xiaomi, etc. (I have always wondered why Chinese names starting with the 'z' sound are spelled with 'X'.)

Now, the sound of x is 'eks', right? Listen to the sound of  'x' here:

So, we can easily substitute 'x' with 'eks' in words that have 'x' embedded inside: compleks for complex; eksellent for excellent, eksuberant for exuberant, etc. We can have many such eksamples...oops, examples.

So, why have the letter 'x' at all? Just have 25 letters in the English language? a, b, c, d.....w, y, z. 

Of course, the letter 'x' has intensive use in Mathematics and a lot of Mathematics would have to be changed if we dropped the letter 'x'. But, we can keep 'x' specifically for Mathematics like (for example) we have the symbol for "for all" as ∀ in Mathematics. And, much in the same way for use of 'x' in Roman numerals, as in, X, XI, XII, etc.

Your thoughts?
