While Etruscan and Latin had /h/ as a phoneme, almost all Romance languages lost the sound—Romanian later re-borrowed the /h/ phoneme from its neighbouring Slavic languages, and Spanish developed a secondary /h/ from /f/, before losing it again; various Spanish dialects have developed [h] as an allophone of /s/ or /x/ in most Spanish-speaking countries, and various dialects of Portuguese use it as an allophone of /ʀ/. ‘H’ is also used in many spelling systems in digraphs and trigraphs, such as ‘ch’, which represents /tʃ/ in Spanish, Galician, Old Portuguese and English, /ʃ/ in French and modern Portuguese, /k/ in Italian, French and English, /x/ in German, Czech, Polish, Slovak, one native word of English and a few loanwords into English, and /ç/ in German.
