Kannadigas are claiming the English word 'Market' came from the Kannada root word 'Maarukatte'(maaruva-selling,katte-an elevated place;.a place for selling)..we don't know exactly,if its true or not,may be some coincidence..words like meen,undu are surely from Dravidian,if its from Sanskrit,why its not using in any of Sanskrit based NI languages?,moreover Sanskrit itself adopted numerous words from other language groups,notably from Dravidian ,both are neighbor language groups too.Maybe the riff raffs on the road will laugh when you speak sanskrized malayalam, most people will consider you cultured and refined.
Same is true for people speaking pig english and refined english. The riff raffs will laugh, while the educated will appreciate.
As usual you are wrong, let me disect your "davidian " malayalam.
" kadalill othiri meenukal undu "
othiri= comes from uccaya in sanskrit which means plenty.
Meenu = also Sanskrit word for Fish. Heard of Meena Rashi ? (Pisces - zodiac) , Meenakshi = Meen (fish), akshi (eyes) eyes like fish (name) Both are sanskrit words.
Undu = also comes from Sanskrit e.g. Sundaram(beautiful / agreeable) ............ undu ~ agree
So any way you slice it, Sanskrit roots can be found in Malayalam.
BTW Samudram is also used liberally in malayalam, as is Kadal. Only Kadal means Sea, Samudram tend to mean ocean.
we can also claim the Sanskrit words like pushpa,mayura were of Dravidian orgin words like poovu,mayil..+Dravidian languages are more ancient than Sanskrit.
