anavara- in Sanskrit means "not inferior; excellent." It consists of an "not" + avara "inferior, low." The Arabic anwar is completely unrelated. It means "brightest, splendid, luminous" and is connected to the Arabic word nūr "light" from the root n-w-r. The Arabic anwar is commonly used as a name as you may be aware; however, I don't believe the Sanskrit word is.
