Aysu is a feminine given name of Turkish and Azerbaijani origin, composed of the elements ay meaning "moon" and su meaning "water". The name evokes natural imagery, conveying a sense of clarity, purity, and beauty akin to moonlight on water. It is used primarily in Turkey and Azerbaijan, and also functions as a surname.Etymology and MeaningThe name is built from two common Turkish and Azerbaijani words: ay (moon) and su (water). As a compound name, Aysu translates to something like "moon water" or "clear as moon and water". This type of composition from nature-inspired elements is a recurring pattern in Turkic naming traditions, where names like Aydan ("from the moon") or Suzan ("of water") also appear.Notable BearersSeveral women have borne Aysu as a given name. Aysu Bankoğlu (born 1989) is a Turkish politician who served as a Member of Parliament for the Republican People's Party. Aysu Keskin (born 1990) is a Turkish basketball player who has played for teams like Fenerbahçe and the Turkish national women's team. Aysu Türkoğlu (born 2001) is a Turkish long-distance swimmer and world champion in open water swimming. The name also appears as a surname, as in Barış Aysu (born 1992), a professional Turkish footballer.Cultural SignificanceIn Turkish and Azerbaijani cultures, names reflecting natural phenomena are cherished for their poetic associations. The moon symbolises beauty, guidance, and – due to its prominence in Islamic motifs – divinity, while water represents life and purity. The compound Aysu harmonises these two powerful elements. It is a moderately popular but distinctive name, especially favoured by parents seeking an elegant and nature-linked choice for daughters.Meaning: "Moon water" or "clear as moon and water"Origin: Turkish and AzerbaijaniType: Feminine given name and surnameUsage regions: Turkey, Azerbaijan
