Cymothoe was a Nereid whose name means swift wave — she calmed the waters for sailors in distress.
Musical and oceanic, it moves like the sea itself.
Cymothoe 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 Cymothoe reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
