Kaya is a name that appears, beautifully, in several unrelated languages: in Hopi it means elder sister; in Turkish, a rock or cliff; and in Scandinavia it serves as a bright pet form of Katarina. Each reading is short and strong.
Simple, sturdy and worldly, Kaya suits almost anyone.
Kaya 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 Kaya reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
