Chiydamal or Chikdamal is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Hamamli (Spitak) district, and currently in the Lori province. The provincial centre lies 20 km to the northwest of the town of Boyuk Garakilsa (Vanadzor), by the Pambak River, at the foot of Chubukhlu Mountain, at a height of 1,930 m above sea level. The village had been within the district of Gugark until 1931. It was integrated into the administrative area of the district of Hamamli (Spitak), which was established in 1937. It was marked on the five-verst map of the Caucasus. There are the remnants of fortress walls going back to the 1st millenium B.C. in the village.

Armenians moved to the area in 1828–1829 from the Iranian province of Maku. Along with the Armenians, seven Azerbaijanis lived there in 1897. The Azerbaijanis were forced to desert the village in the early 20th century. At present, only Armenians live there.

The toponym was coined by combining the word “chik” used in Turkish in the sense of “a border, demarcation” and the word “dam” used in Azerbaijani in the sense of “a house, building”, “a construction with one or two sides open and the top closed”. The ending “-al” at the end of the toponym is a topoformant. The word “chik” is also used in the sense of “a narrow valley” in Turkish.

The name of the village denotes “a house, settlement or village located on the border”. It is a complex toponym formed on the basis of a relief. The village was renamed “Arevashog” by the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 25 January 1978. 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 Lori province.
