Aysel is a Turkish and Azerbaijani name built from ay, moon, and sel, flood or torrent, and is understood as "moonlight" or "flood of moonlight". It is a classic in Turkey and the Caucasus and has arrived in the United States with Turkish and Azerbaijani families and parents looking for Ay- names like Aylin. Aysel was almost unused in 2015, leaped from around number 3040 in 2022 to a peak of number 1636 in 2023 and ranks number 2038 in 2025.
