Tsybik is from the Buryat Цыбик (Tsybik) — Buryat rendition of Tibetan ཚེ་འཕེལ་ (tshe 'phel — life + increase, long-lived). Tsybik is one of the Buryat unisex names — central to traditional Buryat Vajrayana Buddhist heritage Tibetan-Mongolian Buddhist longevity-naming tradition.
Tsybik 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 Tsybik reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
