"Variant of Zion"
The name Tsion is commonly a unisex name from the "Hebrew" origin.
Tsion is the Amharic form of Zion, the Hebrew name of the Jerusalem hill that appears throughout the Bible. It is used as a personal name in Ethiopia, and Latin-script transliterations of it appear as Tsion, Tzion or Sion. The name reached United States birth records in the 1990s, which reflects recent migration and diaspora usage rather than the age of the name itself.
Zion means "Sunny, elevated.".
The pronunciation of Tsion is TSEE-on.
