Keskesor means a rainbow — the bright arc of colour after rain. It carries wonder, hope and joy.
Keskesor 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 Keskesor reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
