Amarsingh was the author of Amarkosha. Amara seems to have been a Buddhist, and most of his work was destroyed, with the exception of what is the celebrated Amara-Kosha (Treasury of Amara), a vocabulary of Sanskrit roots, in three books, and hence sometimes called Trikanda or the "Tripartite". It is also known as "Namalinganushasana". It contains 10,000 words, and is arranged, like other works of its class. The first chapter of the Kosha was printed in Rome in Tamil character in 1798.
