Kunjika is a little bower or shaded grove, from kuñja — a green, sheltered place. In another sense it means a key, that which opens.
Kunjika 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 Kunjika reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
