The Study aims to highlight the Case markers in Bodo specially the dual case marking system. The Bodo is a Tribal language of north east India which is belongs to the Tibeto-Burman branch of the greater Sino-Tibetan language family. The Bodo has eight main case markers. These case markers are morphologically marked as a suffix form with Nouns or pronouns. It is important to know that in Bodo, the genitive case marker can accommodate almost all other case markers along with it, except the ablative case marker. This duality case marking system is a special character of the Bodo language.
