The Hittite corpus is the most extensive among Anatolian languages. It spans from 1650-1140 BC and comprises texts of different genres, ranging from historical texts and letters through administrative and legal to mythological texts, prayers and rituals. The Catalogue de Textes Hittite (CTH, first composed by Emanuel Laroche in 1972), contains almost one thousand individual entries where each of them may consist of several copies of the same text written on several tablet fragments.

The texts were written in Hittite cuneiform script. The language was deciphered by a Czech scientist Bedřich Hrozný in 1915.

Hittite is a fusional language with a basic SOV word order. Adjectives in Hittite are an open word class with productive adjective derivation; they can be based on nouns, verbs and adverbs. They function both as a copula complement and a noun phrase modifier. They inflect for singular and plural, two gendres (commune and neuter) and up to ten cases in singular: nominative, accusative (merged for neuters), ergative (disputed by some scientists), genitive, dative-locative, vocative, allative (only singular), ablative, instrumental (the latter two cases are indifferent to number). In plural, genitive merged with dative-locative.
