Munis is from the Tajik / Arabic مُؤْنِس (Munis — intimate friend, companion, close confidant). Munis is one of the Tajik + Central Asian feminine names — central to traditional Tajik-Persian + Arabic Sufi heritage.
Munis 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 Munis reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
