The purpose of this paper is to prove that intercultural relationship and sufficient contact between Hausa and other languages result in linguistic diffusion or borrowing. The study adopts both the historical and descriptive survey research design, predicated on the need for a brief history of Hausa and the donor languages, and descriptive design to facilitate the use of secondary data generated from textbooks, theses, dissertations, seminar and conference papers. The study traces the location of Hausa people in order to vividly comprehend the nature of contact with the donor languages which effectively bears on the objective nature of the borrowed words. It is in this light that three types of language relationship emerged: genetic, typological and cultural. The intercultural relationship can be unidirectional (English and Hausa) or bi-directional (Hausa and Yoruba). The work provides concrete examples from Tuareg, Fulfulde, Kanuri, Yoruba, Nupe, Arabic and English languages to demonstrate the long contact with the Hausa language. The study finally observes suppressive interference on the structures of Hausa especially from Arabic and English, which have attained second language status in Hausa society, which, again, does not make the language lose its originality.
