Nirukta (Sanskrit: निरुक्त, IPA: [n̪iɾuktɐ], “explained, interpreted”) is one of the six ancient Vedangas, or ancillary science connected with the Vedas – the scriptures of Hinduism

Nirukta covers etymology, and is the study concerned with correct interpretation of Sanskrit words in the Vedas

Nirukta is the systematic creation of a glossary and it discusses how to understand archaic, uncommon words

The field grew probably because almost a quarter of words in the Vedic texts composed in the 2nd-millennium BCE appear just once
