In the Armenian literary Yerevan is mentioned as Yervan, Erevan, Ervan, Eruan, Arevan and in other forms.
In the works of foreign travellers and investigators Yerevan is mentioned as Erivan Irvan, Iravan, E…revan, Irevan and in other forms.
It is known that in Armenian highlands there are a lot of geographical, personal names beginning with Ar, Er, Ur, Ir: Ararat, Aragats, Ara, Araks, Aratsani, Armavir, Archesh… This phenomenon has a link to the name of the Creater (Ararich, God Ar) and his adorers indigenes of Ararat highlands Hay Armens (Armen, Ari /Eri).
We can notice that the names of Erivan, Arivan, Irevan also begin with the constituent parts Ar-, Er-, Ir-. The second part of the name is the constituent part –van. In Armenian highlands there are a lot of settlements,which have the ending -van: Van, Nakhijevan, Ijevan, Ditsavan, Otevan, Avan, Vanq and so on.In all the versions –van has the meaning of a place,settlement.In the name of Yerevan there is also the ending –van. And the roots Ar-, Er- of the word have a link to the name of the Ari,Eri tribe. So we can say, that the versions of the name of Yerevan Arevan, Aravan, Erivan are formed from the component parts Ar-, Er- and –van, which has the meaning of the land (in Armenian language- avan) of the Ari ot Eri tribe,adorers of the God Ar (the Creater).
The name of Erebuni mentioned in the report of Arguishti the First, also speaks for the name of land (avan) of the Ari (Eri) tribe. In Urartian cuneiforms ebani has the meaning of land, settlement. The researchers consider the Armenian avan and famous ebani /b=v/ from Urartian reports as words having the same meaning. As we see, in this case Erebuni can be read as a settlement of the Ari or Eri tribe. It`s necessary to remind, that in notes of foreign travellers Yerevan in Persian version is mentioned in Irivan, Irvan, Irevan, Iravan, Eriavan forms.The Persian form of Yerevan used by the Persians, the oldest neighbours and kinsmen of Armenia, also proves that the name of Yerevan has the meaning of the settlement of the Ari (Eri) tribe. For the comparison we can remind the name of Iran, when among the Persians the component part Ar- is used in a form of Ir-. And even one of the researchers Anqetil supposes, that the name Yerevan has likeness to the name of Eerien Veedjo or mentioned in “Zend Avesta”.
As a conclusion we can say, that the name of the capital Yerevan has the meaning of the land of the Ari or Eri trib or the settlement of the Aryan tribe.
