Mioara is the Romanian word for a young female lamb — diminutive of mioa (ewe). The Romanian folk ballad Miorița (The Little Ewe-Lamb) is considered the work of Romanian folk poetry.
Mioara is widely used in Romania.
Mioara 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 Mioara reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
