This book consists of verses that can be easily memorized. The book was originally called by Amarasimha as Ithyaamarasimhakruthov Namalinganushasane (Book of instruction concerning the gender of nouns written by Amarasimha), but is generally referred to as Amarakosam.
Svargadhikanda, the first Kandam of Amarakosham begins with the verse 'Svaravyam swarganakathridivatrishalaya..' describing various names of Heaven viz. Sva, Avya, swarga, Naka, Tridiva, Tridasalaya etc. The second verse 'Amara, nirjara, deva,’ describes various words that are equivalent to word God. The fifth and sixth verses give various names of Gautama Buddha reinforcing the claim that he is a Buddhist.
The second Kandam, Bhuvargadhikanda, of Amarakosham is divided into ten Vargas or parts. The ten Vargas are Bhuvarga (Earth), Puravarga (Towns or Cities), Shailavarga (Mountains), Vanoshadivarga (Forests and medicines), Simhadivarga (Lions and other animals), Manushyavarga (Mankind), Bramhavarga (Brahmin), Kshatriyavarga (Kshatriyas), Vysyavarga (Vysyas) and Sudravarga (Sudras).
The Third Kandam, Samanyadhikanda contains Adjectives, Verbs, words related to prayer and business etc.. The first verse Kshemankaroristatathi Shivathathi Shivamkara gives the Nanarthas of the word Shubakara or propitious as Kshemankara, Aristathathi, Shivathathi and Shivamkara.
The Amarakoshad-ghatana is a commentary by Kshirasvamin.
