A South Slavic name related to Savva or Sabbas, traditionally interpreted as "elder" or "old man."
Sava carries the dignity of sainthood and the echo of one of Europe's great rivers. The name derives from the Hebrew "Sabas" or "Saba," meaning old man or wise elder, and entered Christian tradition through Saint Sabas of Cappadocia (439–532 AD), a Palestinian monk who founded the famous Mar Saba monastery in the Judean Desert — one of the oldest continuously inhabited monasteries in the world. From this early Christian root, the name spread through Byzantine and Slavic Christianity with remarkable reach.
Its most celebrated bearer in Slavic history is Saint Sava of Serbia (1175–1236), born Prince Rastko Nemanjić, son of the great Serbian ruler Stefan Nemanja. Sava renounced his princely title, became a monk on Mount Athos, and ultimately became the first Archbishop of the autocephalous Serbian Orthodox Church. He is venerated as the patron saint of Serbia, of education, and of medicine — a figure who unified a nation through spiritual authority rather than military conquest.
January 27 is celebrated as Savindان (Sava's Day) across Serbia and neighboring countries, a school holiday honoring the saint's foundational role in Serbian literacy and learning. The Sava River, which flows through Ljubljana, Zagreb, Belgrade, and into the Danube, shares the name — its etymology traced to pre-Slavic roots possibly meaning swift or the water itself. In contemporary usage, Sava is given in Serbian, Croatian, Bulgarian, and Georgian families, and has begun appearing in Western Europe and North America as parents seek short, strong, historically resonant names. It sits cleanly — one syllable of compressed history.
