Neelakai – நீலகை

Neelakai likely combines Tamil elements meaning "blue" (neela) and "hand" (kai), so it can be read literally as "blue hand" or "blue-hued hand." As a given name it may be used poetically, with the color blue evoking calmness, depth, or the sky and sea. The form appears to be uncommon or regional, so exact cultural use varies and is not widely documented.
