Anoma is a Sinhala (Sri Lankan) name from the Sanskrit anupama, meaning "peerless" or "without comparison."
Anoma is widely used in Sri Lanka.
Anoma 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 Anoma reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
