Tubeteika
A tubeteika (Tajik: тоқӣ, Tajik: тӯппӣ in Northern Tajikistan, Uzbek: doʻppi / дўппи, Kazakh: төбетей, тақия, Kyrgyz: тебетей, суусар тумак, Tatar: түбәтәй; Russian: тюбете́йка, romanized: tyubeteika, IPA: [tʲʉbʲɪˈtʲeɪ̯kə] ⓘ) is a Russian word for many varieties of traditional Central Asian caps. Tubeteikas are today worn in Tajikistan, Kazakhstan, Kyrgyzstan, and Uzbekistan, as well as in Muslim-populated regions of Russia (mainly Tatars) and Azerbaijan. The skullcap worn by Uzbeks and Uyghurs is called a doppa and has a square base. It was a popular headgear among children throughout the USSR during the 1940s and 1950s.
Tubeteikas differ greatly between different people of the region and even between different regions of same countries. Tajik toqis feature a great variety of styles, ranging from square black-and-white ones in Sughd to round multicolored styles in the Southern regions including Khatlon and round red, green and other styles in the east (Pamir). Turkic varieties bear some superficial resemblance to the yurt, another Central Asian cultural icon.
The -ka at the end is a Russian diminutive suffix, as with shapka, ushanka, kubanka, pilotka and budenovka. In Turkmen, it is called tahiya ("taqiyah").
