Sami is from the Quechua sami — good fortune, blessing + dual-origin from Arabic سَامِي (Sāmī — elevated, noble) + Hebrew שמואל (Shemu'el short form Sam) + Sami Indigenous Northern European Sápmi people. Sami is one of the Quechua feminine + unisex names Arabic + Sami Indigenous unisex name.
Sami does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Sami reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
