The south was sa-arth (which means with purpose, as east is ast, west is vvast ot uuast ot Ust, and north is na-arth).
When we do ceremonies, we face east and right hand is facing south. Right hand also means dextrous and is connected with dakS-tra-uah (which becomes ous in Greek). This is why South was called dakS-iN.
I always found South people to be more Spiritual and Intellectual - this can be explained historically or through Islamic Conquest (why do so many Tamil Brahmins still chant in Sanskrit?). In fact India is saved because of South (imagine India full of Punjabi Islmic confused people).
I think dravidians is basically drav-ya-vidyA-N or the people who relic the sutble spirt(ual) nectar knowledge pracrioner. This is also blessed by the Shaivism fact which also has aspects of Yoga and Vedenta. This is my Shaivism and Siddhas were more prevelant. Britishers could not spell it.
Druids are also drav-vidyA-N
