There doesn't seem to be a widely recognized dictionary definition for "Azar Kayvan." It appears to be a specific name or combination of names, potentially of Persian or Iranian origin. However, in lieu of providing a dictionary definition, here is some information about the individual names in order to provide some context.
1. Azar: "Azar" is a name commonly used in Persian-speaking countries. It has Persian and Avestan origins and can have multiple meanings, including "fire," "intense," or "passionate." In Persian mythology, Azar is associated with the element of fire and is an essential figure in Zoroastrianism.
2. Kayvan: "Kayvan" is another Persian name derived from the Arabic word "Kayvanjah" or "Kayvanjeh," meaning "planetary" or "celestial." It is often used as a male given name and is associated with nobility and charm.
It is important to note that names cannot be given an official dictionary definition because they are specific to individuals and their cultural backgrounds. The definition and significance of a name usually depend on the cultural context and the personal or family associations attached to it. Thus, without further information about the specific context or individual referred to as "Azar Kayvan," it is challenging to provide an accurate dictionary definition.
