“…In Hittite, reflexivity is coded by the particle -za-, which however does not have a pronominal origin, and which appears in the clause initial chain of clitics. Owing to this diversity, the reconstruction of a PIE reflexive form is controversial (Calboli 2000), and some scholars such as Puddu (2005) The fact that the adjective was not considered as an autonomous part of speech in the classical grammatical tradition may also find a correspondence in typology: since Dixon (1977), it is acknowledged that many languages lack adjectives or restrict them to few functions such as age ("old," "new"), dimension ("little," "big," "long," "short"), value ("good," "bad"), or colour ("black," "white," "red"), while other qualities are coded by nouns or verbs (cf. also Wetzer 1996; Dixon and Aikhenvald 2004).…”
