<a href="#" class="seekto" data-time="490">8:10</a> X is important in printing because it reaches all 4 corners equally. It is the standard by which all letters are measured in setting a typeface. From it you can calculate descenders (e.g. length of the tail on letter 'g'), ascenders (e.g. height of a letter 'h') and differing widths of letters (e.g. 'i' is thinner than 'd'), to set the spacing of words and lines when letters were physical blocks plated with ink. The principles still apply in the digital equivalent. Different typefaces take up different amounts of space on a printed page (or screen) depending on their dimensions relative to the standard 'X'.

<a href="#" class="seekto" data-time="402">6:42</a> actually Old Spanish did have a letter to represent the SH sound, it was the letter X! this is because the sequence KS from Latin turned into a sh sound in Old Spanish (like in "laxius" > "lexos"), which still existed in the 1500s and 1600s, but which shifted to a H sound in modern Spanish ("lexos" > "lejos"). It is now spelled as J because the Old Spanish letter J represented a ZH sound (similar to the SI in vision), but this sound also became H in modern Spanish so there was no point in keeping the distinction in writing, and since J was more common all of the X got replaced with J, except in a few words like México, which is pronounced as tho it was written Méjico. In Portuguese and Catalan, which are both closely related to Spanish, the letter X is still pronounced as the SH sound, tho now Portuguese prefers spelling it as CH for similar reasons to the ones that led Spanish to prefer J for the H sound Now this is all really simplified and dumbed down to the best of my abilities but there's still a whole lot of stuff that could be explained in more detail. My point is just that Spanish already had the X letter for the Arabic SH sound, so there's no need to say they borrowed Greek Chi, which adds more force to the hypothesis by making it simpler

In Arab world we use “س” The letter “س” (sīn) is phonetically simple and easy to write, making it a convenient choice for representing an unknown value .In Arabic, the word for unknown or mystery can be represented by the root “س” (sīn). This makes “س” a natural and intuitive choice for an unknown variable.

Well Finnish does not use Q at all. Words that in English have "qu" use "kv" instead (like kvantti). Well X is neither used, instead "ks" is used (Taksi), well we do not use Z much either, still for some reason we have two versions of it Z and Ž. The latter only so that we can write Russian names.

I think it has a bit to do with how simple and elegant the letter is. X is very simple and district. Unlike p for example that is curved and also is similar to q d and b. And that matters when you're trying to grab someone attention, such as with a logo. That is not to say other letters can not have the same effect. The Q in game Quake is very iconic. But it does not look like your regular Q. While most uses of X do very much look like a X.

When writing quickly, like on a chalkboard, X is the easiest letter to write after the letter I. But in algebraic problems, I looks too much like 1, so X is more useful and doesn’t look like anything else. Also you don’t have to be very careful when writing X. With most other letters or numbers, there can be confusion, but X looks like X no matter how sloppily it’s written.

I think it's strange that the English alphabet has two letters that make the same sound as a combination of two other consonants, but not even commonly occurring consonant pairs. So not only do these letters not make their own sound, they don't even represent commonly used sound combinations, so it's not like they justify their place in the alphabet as useful shorthand. Meanwhile, English has some commonly used sounds that don't have their own letters to represent them.

@@maythesciencebewithyou Maybe it's possible to replace those combinations with some other letter. Such as "ʃ" which is used for this sound in IPA. ʃip, Deutʃland, ʃarp. But adding this may make English spelling harder and more confusing. And a better solution may be an already existing letter with diacritics, such as ś, š or ç. And such changes are kind of useless

In my eyes it seems likely that the same sort of thing happened as what you feel when naming variables in programming. You want to make absolutely sure that you don’t repeat yourself on accident so you pick something you feel is „secluded“, „rare“ or „far away“ from the other variables you named.
