The letter {{angbr|X}}, representing {{IPA|/ks/}}, was inherited from the [[Etruscan alphabet]]. It perhaps originated in the {{angbr|Χ}} of the [[Archaic Greek alphabets#Euboean|Euboean alphabet]] or another Western Greek alphabet, which also represented {{IPA|/ks/}}. Its relationship with the {{angbr|Χ}} of the Eastern Greek alphabets, which represented {{IPA|/kʰ/}}, is uncertain.

The pronunciation of {{IPA|/ks/}} in the [[Romance languages]] underwent [[Palatalization in the Romance languages|sound changes]], with various outcomes:
* [[French language|French]]: {{IPA|/js/}} (e.g. ''laisser'' from ''laxare'')
* [[Italian language|Italian]]: {{IPA|/ss/}} (e.g. ''asse'' from ''axem'') and, in some cases, {{IPA|/ʃʃ/}} (e.g. ''lasciare'' from ''laxare'')
* [[Portuguese language|Portuguese]]: {{IPA|/jʃ/}} (e.g. ''eixo'' from ''axem'')
* [[Romanian language|Romanian]]: {{IPA|/ps/}} (e.g. ''coapsă'' from ''coxa'') and {{IPA|/s/}} (e.g. ''lăsa'' from ''laxare'')
* [[Old Spanish]]: {{IPA|/ʃ/}}
** [[Spanish language|Spanish]]: {{IPA|/x/}} (e.g. ''cuja'' from ''coxa'')
In Old Spanish, {{angbr|x}} came to represent {{IPA|/ʃ/}}, which it still represents in most [[Iberian languages]] and in the orthographies of other languages influenced by Spanish, such as [[Nahuatl language|Nahuatl]]. In French (with a few exceptions), Italian, Romanian, and modern Spanish, {{angbr|x}} was replaced by other letters.

The use of {{angbr|x}} to represent {{IPA|/ks/}} was reintroduced to the Romance languages via Latin [[loanword]]s. In many words, the {{IPA|/ks/}} was [[Consonant voicing and devoicing|voiced]] as {{IPA|/gz/}}.
