Maybe it's the pronunciation - ente means "mine" and ante means "yours" (in Malayalam) which is what perhaps you may be referring to? (Former South Indian kingdoms and South East Asia have historical cultural ties due to trade and conquest, and thus they share some common words, which I assume is, largely borrowed from Tamil and Malayalam).
By other indians. And indian military use malayalam to communicate, so that enemies cannot intercept. There was a report that chinese started learning south indian languages. Most movies use neutral phonetics (written language) where as spoken language is tough to understand and have many regional vriations.
Fascinating how sometimes in different languages one word can have opposite meaning and the other times one word can have similar meaning.
