How were enclitic pronouns used in Anatolian languages?

In the Anatolian languages, enclitic pronouns are unaccented forms that attach to a preceding accented word within a sentence. The Anatolian group significantly elaborated upon the inherited Indo-European system for these pronouns.1

Their usage is characterized by the following:

• Attachment: They are appended to the first accented word of a sentence, which often includes sentence-initial conjunctions.1
• Function: They serve to indicate grammatical roles, such as direct or indirect objects. For example, in the Hittite phrase kuenzi-us ("kills them"), the enclitic -us functions as the direct object "them".1
• Complex Sequences: Anatolian languages frequently combine enclitic pronouns with various other particles into long strings attached to the initial word. A notable example is the Hittite construction nu-war-at-si-kan dānzi ("they take it from him"), where the sequence includes a conjunction (nu), a quotation marker (-war-), a direct object pronoun (-at-), an indirect object pronoun (-si-), and an additional particle (-kan).1
