Roshanak ( from Young Avestan raoxšna-; adjective: "shining, bright" noun: "light") is a traditional Iranian name for a female.
This name has several meanings such as shining star, lovely flare and luminous beauty.
Roxana is the Greek pronunciation of this name and refers to a Bactrian noblewoman who was the daughter of Oxyartes of Bactria (not Sogdiana) and the official wife of Alexander the Great. Bactria was in the northeastern part of the Persian Achaemenid Empire, defeated by Alexander's army in 330 BCE.
It is also the name of Dara's daughter (Dara is a character in Shahnama, likely referring to the Darius of the Achaemenid Empire).
The names Roxanne and Roxane are English and French variants of this name respectively. Diminutives include "Roxie" and "Roxy". For example, Roxane is the name of Cyrano's love in the famous French play Cyrano de Bergerac by Edmond Rostand.
In Spanish and Romanian, the form Roxana is used; while Ruxandra is a Romanian variant. Russian, Ukrainian, and Polish use the same form which is Roksana (Роксана). There used to be an eastern Iranian tribe called the Roxolani in eastern Europe around present day Ukraine, Moldovia and Romania.
Sultan Suleiman the Magnificent of Turkey defied Ottoman tradition to free and marry his concubine Hurrem or Roxelana as she was known in Europe.
This name is still popular and in common use in today's Iran. The diminutive form "Roshie" is sometimes heard.
