I started to learn sanskrit few years ago. but due to circumstances I am unable to continue. During that little precious time I remember my Guru told me that there are 10 different types of grammar available in sanskrit and Lord Hanuman knows all of them. But today we use pannini grammar. So the question is what happened to the rest of the 9 types of grammar (hope i heard him correctly i vaugly remember this since its been a long time).
There are dasha lakaara-s or 10 tenses/moods in Sanskrit grammar - it might be that reference to the number 10
language is different.
The latter is called just Vedic in English, or Vedic "Sanskrit". Here in Finland, it's called muinais-intia (ancient Indic). IMHO, in many respects, Sanskrit is a simplified form of the Vedic language, sometimes with all too many long samaasas (compound words), perhaps to avoid remembering the sometimes rather complicated saMdhis and nominal suffixes?? - - Jaya Gurudeva, guru of Maharishi Mahesh Yogi (maharSi mahesh yogii?).
