నీరు

Nīru is the Telugu and Kannada word for water. In Tamil, it is nīr. In Malayalam, nīr. In Tulu, nīrŭ. The word is reconstructed to Proto-Dravidian as *nīr and means exactly what it meant four millennia ago: water. It is one of the most stable words in the Dravidian language family, showing almost no semantic drift across thousands of years and dozens of daughter languages.

The word appears in the oldest Tamil literature and in stone inscriptions throughout South India. Place names carry it: Nīr in various compounds means water, river, lake, or irrigated land. The Kannada place name Nīlagiri (blue mountain) pairs a color with the landscape. Tamil compound words like nīrāḍu (to bathe, literally 'to play in water') and nīrōṭṭam (irrigation flow) show how the root generates vocabulary. Linguist Bhadriraju Krishnamurti used nīr as one of his key examples of Proto-Dravidian vocabulary stability.

Nīr and its cognates also appear in Dravidian loanwords that entered Indo-Aryan languages. The Hindi word nīr (water, used in literary and poetic registers) may be a Dravidian borrowing rather than a cognate of the Sanskrit nīra. This is debated, but the existence of the debate itself shows how deeply Dravidian water vocabulary penetrated the Indo-Aryan world. The Dravidian word for water may have influenced how hundreds of millions of Hindi speakers talk about water, even if they do not know it.

Modern Telugu and Kannada use nīru as the basic, everyday word for water. It is the first word a child learns for the substance. It appears on water bottles, in government slogans about water conservation, in agricultural extension pamphlets. The word has not acquired metaphorical layers. It has not narrowed or broadened. It is water. It was always water.
