Dedegishlag is a village in the Novo-Bayazid uezd of the former Iravan governorate, later in the former Akhta (Hrazdan) district, and currently in the Kotayk province. The provincial centre lies 20 km to the northwest of the town of Hrazdan, by the Miskhana River and at a height of 1,850 m above sea level. It was marked on the five-verst map of the Caucasus.

The village was inhabited only by Azerbaijanis: 23 in 1831, 196 in 1873, 278 in 1886, 341 in 1897, 428 in 1908, 541 in 1914 and 442 Azerbaijanis in 1916. In 1918 the Azerbaijanis were massacred or ousted by Armenian armed units. The survivors managed to return to their homes after Soviet power had been established in present-day Armenia. The village was inhabited by 186 Azerbaijanis in 1922, 237 in 1926, 305 in 1931, 401 in 1939, 455 in 1959, 814 in 1970 and 925 Azerbaijanis in 1979. In late November 1988 the inhabitants of the village, the Azerbaijanis, were either massacred or forced to leave the place. Presently, only Armenians live in the village.

The toponym was formed by combining the ethnonym “dede” which is one of the clans of the Turkic Taka tribe and the word gishlag (in Azerbaijani: winter pasture) to denote “a winter pasture belonging to the tribe “Dede”. It is an ethnotoponym. Another name for the village was Gaygojali. The toponym was coined by adding the suffix “-lı” denoting identity to the personal name “Gaygoja” and meant “an area, settlement belonging to Gaygoja”. The first part of the toponym “Gaygoja” consists of the ethnonym “Gayi”, one of the Turkic tribes and the personal name “Goja”. Gaygojali was coined in direct association with the epos “The Book of Dede Korkut”.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 4 May 1939, the village was renamed “Akhundov“, and further changed to become “Pyunik“ by decision of the Armenian Parliament dated 4 May 2006. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Kotayk province.
