தூவிகா and தூவிதா both are good options....... unique, nice sounding, pure tamil name ... inga neenga koduthirukkara meaning also good...... (சிறகைக் காத்தருள்....)

actually, I am not very much obsessed with meanings in other languages......... but sanskrit naan perithum respect panna koodiya oru language, thatz why looking at the meaning if a derived version of that name is available in sanskrit

stumbled upon this name: விகிர்தா - a sweet name and seems like it denotes Lord Shiva in many shaiva literature and in general meaning GOD, seems like it is derived from Sanskrit

Another doubt..... will அருள் + நீ + தா would become அருணிதா? One another option that I had in mind was அருணிதா, Arunachalam is my Grandmother's name, Arunachalam also refers to Lord Siva, so athula irunthu Aruna va eduthu, athukku oru suffix thaa add panna, Arunitha nu kondu vanthu athai அருள் + நீ + தா ngra maathiriyum kondu vara mudiyuma nu yosichittu irunthaen..... (Another advantage of this word: in Sanskrit Arunita means Sun / Red as used in different context)

Well, naan romba yosichu confuse pannikarennu yaarum ninaikatheenga... vaikka porathu ennamo ore oru name than..........but this also gave me an opportunity to dig into old tamil words etc., and come up with more choices of pure sweet tamil words thatz why showing more interest.......
