Hittite phonology
Hittite phonology is the description of the reconstructed phonology or pronunciation of the Hittite language. Because Hittite as a spoken language is extinct, thus leaving no living daughter languages, and no contemporary descriptions of the pronunciation are known, little can be said with certainty about the phonetics and the  phonology of the language. Some conclusions can be made, however, by noting its relationship to the other Indo-European languages, by studying its orthography and by comparing loanwords from nearby languages.
