Here's a breakdown of the sentence:
* enik: This is the dative case of "enikku," which means "to me" or "for me."
* ningal: This means "you" (plural).
* byankara: This means "very" or "extremely."
* ishtannu: This means "like" or "love."
The sentence is a direct translation of "I like you very much," but in Malayalam, it conveys a stronger sense of affection and liking.
