Some of the modern linguistics suggests that all languages are equal in so far as their natural potential for development is concerned. Hence, no language is inferior to any other language in the world. But languages do progress and flourish to meet the demands of day to day life. Siraiki, as one of the oldest languages spoken in this part of the world, has rich literature or a vast vocabulary, but its progress along the line of modern sciences and their terminologies has been rather slow. In this article, some basic principles for term-making have been laid down and followed in the proposed Siraiki terms relating to arts, literature, languages, grammar and some of the modern, concepts. A suffix to substitute the 'ology' or 'logy' has been suggested to be used in Siraiki. Most of the terms have been derived from classical Siraiki language & literature.
