Kak (title)

Kak (Kurdish: کاک)^[a][b] is a traditional honorific title in Kurdish society, commonly used to address or refer to men with respect.^[5][6][7] The term literally translates to "elder brother",^[8] "brother",^[9] or mister^[10] and is often used to convey familiarity, respect, or social status. It can also be used to refer to an "uncle".^[11]

Several prominent leaders of Kurdish movements in both Iraqi Kurdistan and Iranian Kurdistan have been known by the title kak. Notable examples include Masoud Barzani,^[12] Nawshirwan Mustafa and Foad Mostafa Soltani.^[13] Within the Kurdish Peshmerga forces, the title kak is commonly used to address any Peshmerga fighter, regardless of rank.^[14]

The word kak is of Iranian origin and is etymologically related to similar forms in other Indo-Iranian languages. It is also thought to descend from the ancient Median language.^[15] During the Median period, it was used for important or noble individuals, including historical figures such as Kuaxarēs. More generally, the term reflects a Kurdish system of religious and social hierarchy, analogous to titles such as Sheikh, Khawaja, or Mawla in neighboring regions.^[16] In Romani, for example, the word káko means "uncle" and is considered a Kurdish loanword, likely derived from Kurdish kak, which carries the same meaning.^[17]

The term is also related to the Kakais, (also spelled Kakeyi) a religious group in Kurdistan Region, which derives from the kak, and literally translates to "belonging to the brotherhood".^[18][19]

As a title, kak functions similarly to other Kurdish honorifics and does not accept grammatical affixes when used in this way. In Kurdish language, titles can appear in two positions relative to a proper name:

1. Immediately before the name, (like kak) e.g.: Mr. or Şêx (Sheikh).
2. Immediately after the name, e.g.: Xanim (Ms.).^[20]
