Amarasimha

Amarasimha (IAST: Amara-siṃha, c. CE 375) was a Sanskrit grammarian and poet from ancient India, of whose personal history hardly anything is known.

[2][3] Most of Amarasiṃha's works were lost, with the exception of the celebrated Amara-Kosha (IAST: Amarakośa) (Treasury of Amara).

The first reliable mention of the Amarakosha is in the Amoghavritti of Shakatayana composed during the reign of Amoghavarsha (814-867 CE)[4] The Amarakosha is a lexicon of Sanskrit words in three books, and hence is sometimes called the Trikāṇḍī or the "Tripartite".

[5] The Amarakosha contains 10,000 words, and is arranged, like other works of its class, in metre, to aid the memory.

An edition of the entire work, with English notes and an index by Henry Thomas Colebrooke appeared at Serampore in 1808.
