Edward Hopkins was a noted scholar of Sanskrit and professor of Sanskrit and comparative philology at Yale. This paper is concerned with the nature of the future tense in Aryan language. Although the idea of the Aryan or Indo-European language speakers later became associated (oddly and inaccurately) with Nordic peoples with disastrous social and political consequences, this paper firmly concerns itself with Aryan as a linguistic ancestor linking Iran and India, and at a further remove the languages of Europe. The paper covers participles and future forms in the Rig-Veda, Indo-Iranic, Sigmatic, and Primitive literary sources and will be of immediate interest to linguists, and perhaps of interest as well to historians of the rise of 'Aryan' from technical term in linguistics to a rallying point for pro-Nordic racist politics.
