My first name is roughly pronounced as /Maania/.
In Persian language, the name Monia is created in two forms:

-- Maan + gaah which over the years has turned to Maania: means a place for tranquility.
-- Maani + aa (aa of relation) which means thinker, unique, rare.

Historically, Monia was the name of one of Artaxerxes II of Persia's rulers in 399 BC.
