The Amarakosha (Sanskrit: अमरकोश, IAST: Amarakośa) from amara "immortal" and kosha "treasure, casket, pail, collection, dictionary", also Namalinganushasana (Sanskrit: नामलिङ्गानुशासनम्, IAST: Nāmaliṅgānuśāsanam) from nama-linga-anu-shasana "instruction concerning nouns and gender") is a thesaurus of Sanskrit written by the Jain or Buddhist scholar Amarasimha. Amarasimha was one of the Navaratnas ("nine gems") at the court of Chandragupta II, a Gupta king who reigned around AD 400. Some sources indicate that he belonged to the period of Vikramaditya of 7th century.
