X Details, Meaning X Article and Explanation Guide

X Guide, Meaning , Facts, Information and Description

X is the twenty-fourth letter of the Latin alphabet. It is also the form of St Andrew's Cross.

/ks/ was in Ancient Greece written as Chi 'Χ' (Western Greek) or Xi 'Ξ' (Eastern Greek). In the end, Chi was standardized as /k_h/ (/x/ in Modern Greek) as well as Xi for /ks/. But the Etruscans took over X from older Western Greek, therefore, it stood for /ks/ in Etruscan and /ks/ and /gs/ [gz] in Latin. Only in Kurdish, Azeri, Uzbek and Tatar as well as the IPA and SAMPA (the latter is used here) is X pronounced [x] (as in German Bach). Some scholars claim that Latin X is not identical with Greek Χ.

It is also controversial whether Psi, Chi (Khi) and Xi are Greek inventions or whether they are ultimately of Semitic origin.
