* Sa (स) - meaning "with" or "together"
* Anvi (अन्वि) - meaning "following" or "seeking"
Therefore, the sandhi viched (word splitting) of Saanvi is Sa + Anvi.
The combined meaning of "Saanvi" is "one who follows or seeks together", or "one who is united in seeking". It can also be interpreted as "one who is devoted to the divine".
