Though the precise Etymology of Assam, a state in India is unclear—there is general agreement that it is related to the Ahom people. Whatever the source of the English name, Assam is itself an anglicization. Scholarly views John Peter Wade (1805) called the Ahom kingdom, that commenced on the Konder Chokey, "Kingdom of Assam". Some have speculated that the Bodo word "Ha-com" meaning low land was Sanskritised to 'Asama', dating its origin to at least first millennium common era. While some believe the name Asama is a Sanskrit originated word which means unparalleled because of its unequal terrain with hills interspersed with valleys Banikanta Kakati quotes Grierson in Linguistic Survey of India that "While the Shan called themselves Tai, they came to be referred to as Āsām, Āsam and sometimes as Acam by the indigenous people of the country. The modern Assamese word Āhom by which the Tai people are known is derived from Āsām or Āsam. The epithet applied to the Shan conquerors was subsequently transferred to the country over which they ruled and thus the name Kāmarūpa was replaced by Āsām, which ultimately took the Sanskritized form Asama, meaning "unequalled, peerless or uneven" Satyendranath Sarma repeats this derivation while quoting Kakati. Colin Masica too endorses this view. Satyendra Nath Sarma writes "Assamese is the easternmost Indo-Aryan language of India, spoken by nearly eight millions of people inhabiting mostly the Brahmaputra valley of Assam. The word Assamese is an English formation built on the same principle as Simhalese or Canarese etc. It is based on the English word Assam by which the British rulers referred to the tract covered by the Brahmaputra valley and its adjoining areas. But the people call their country Asama and their language Asamiya". Early names Kamarupa The earliest epigraphic mention of the Assam region comes from Samudragupta's Allahabad stone pillar from the fourth century CE, where it is called Kamarupa. The pillar lists the frontier kingdoms (pratyanta nripati) and lists Kamarupa (Western Assam) along with Davaka, a region in the central Assam (undivided Nagaon district). Therefore, during the fourth century, the eastern boundary of the Kamarupa did not extend beyond west Assam. The Kalika Purana (10th century) and the Yogini Tantra (16th/17th century) refer to Kamarupa as a kingdom from Karatoya in the west to Dikkaravasini in the east. Dikkaravasini is identified with present-day Sadiya. The copper-plate inscription from Vaidyadeva calls Kamarupa a mandala
