Aysun is a Turkish feminine given name whose etymology combines the Turkish word ay meaning "moon" with an uncertain second element. The name is also attested historically as a male Arabic name, as seen in the medieval figure Aysun ibn Sulayman al-Arabi, also spelled Ayxun, who was active in 8th-century al-Andalus.Etymology and Cultural SignificanceThe first element, ay ("moon"), is a common component in Turkish names, often symbolizing beauty and grace. The second element remains unclear, but possibilities include the Persian suffix -sun (meaning "face" or "quality") or a derivation from the Old Turkic word sün ("brave"). In modern Turkish, the name is exclusive to females, contrasting with its historical Arabic context.Historical Bearer: Aysun ibn Sulayman al-ArabiThe most prominent historical figure bearing this name is Aysun ibn Sulayman ibn Yaqdhan al-Arabi (Arabic: عيشون بن سليمان بن يقظان الكلبي الأعرابي), often referred to as Ayxun or Aisso. He was the son of Sulayman al-Arabi, the wali (governor) of Barcelona and Girona in the late 8th century. Aysun and his father allied with Charlemagne during the siege of Zaragoza in 778. When Charlemagne took hostages, including Sulayman, Aysun and his brother Matruh allied with the Basques and attacked the Frankish baggage train at the Battle of Roncesvaux, freeing their father. After Sulayman's death in 780, Aysun transferred his allegiance to Emir Abd al-Rahman I of Cordoba.Notable BearersTunç Aysun, Turkish painter (born 1974)While Aysun is not a commonly encountered name in international contexts, it has a steady presence in modern Turkey.
