I am constantly amazed at how often someone says "Sanskrit is the mother of all languages in the world"... as there are thousands of languages from several different genetically unrelated families - HERE is a good list.
Sanskrit is in the Indo-European family and has no genetic affinity to languages in other parts of the world outside this family. Even though there are hundreds of loan words in the earliest stratum. If you hear a yoga teacher or anyone repeat the sentence above...or this one: "Sanskrit is the oldest, purest language in the world, and is the best for computing languages", then they are either completely ignorant OR have an agenda. LIke this organisation.
This is something that seems to be particularly idiosyncratic to India, as lovers of Tamil also claim the same thing.
You might like this site, it has sound changes from PIE over time and if you're interested, this is the source of the word 'mother' in all IE languages.
