This chapter presents commonly used terms in the study of postcolonialism. The terms listed begin with the alphabet “A”. Detailed explanation is provided for several terms, including aboriginal, abrogation, adivasi, agency and alterity. Each entry includes the origin of the term; a detailed explanation of its perceived meaning; and examples of the term's use in literary‐cultural texts. The term aboriginal was used as shorthand for any 'non‐European' and homogenized Maoris, the many Native American tribes, the numerous language groups and ethnic formations of these regions. Abrogation's key contribution to postcolonialism's political stance lies not only in its rejection‐appropriation dynamics of language but also in its shift away from the standard‐non‐standard idea of language and therefore of culture. The institutionalization of alterity enables the European to present him‐/herself as saviour, benefactor, ruler and modern and crucial to the colonial enterprise.
