x

History of the International Phonetic Alphabet

Pronunciation of IPA [xa axa] with the sound [x]

The variable name comes from usage in Spain, as up to the 16th century ⟨x⟩ had the sound value /ʃ/ in Spanish, so was used to transcribe Arabic ش (š) used for the purpose of a variable as an abbreviation of شَيْء (šayʔ, “thing”). Its sound value in Spanish has since then become /x/, which explains the decision made in the circle of the International Phonetic Association to assign this character to the voiceless velar fricative. Compare English hickey (“an object whose name is not recalled; bruise-like mark made during petting by pressing the mouth to the skin”) for the development of the sense of a communicated kiss.
