Korbulag is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Gizil Goch (Gukasyan) district, and currently in the Shirak province. The provincial centre lies 44 km to the north of the town of Gumru, at a height of 2,075 m above sea level.

According to the Treaty of Adrianople (1829), following the settlement of Armenians in the village, the Azerbaijanis moved to Türkiye. In their works Armenian authors mention the village as “Koraghbyur” (Korbulag).

The toponym was coined by combining the word “kor” (blind) and the word “bulag” (a spring) in the Azerbaijani language, which implies “a spring without a wayout, basin, half-dried”. The name of the village was derived from the spring by the same name in that area. It is a hydrotoponym.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 12 November 1946, the name of the village was changed to “Sakhkashen”, and by decision dated 21 October 1967, it was renamed “Sizavet”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative territory of the Shirak province.
