Kodhai means a garland of flowers, and by extension a lovely young woman — famously the name of the saint-poet Andal. It joins bloom and grace.
It reads fragrant and devout, beauty woven together.
Kodhai 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 Kodhai reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
