These three articles translated from French were published in a collective work, concerning the issues “Comparative History and Intersectional History,” “Structuralism,” and “The History of Terminology.” These articles all offer the researcher approaches that enrich research methods in the social sciences and humanities, inasmuch as they stimulate interest in the overlaps and intersections between these sciences and in sanctioning the suitable methodology and stress the vitality of between academic disciplines, which leads to reviewing, rethinking, and revising the usage of research tools and the reaching of conclusions. These articles also shed light on the importance of dealing with terminology and concepts as their meanings develop, their usages grow more diverse, and they are transmitted from one discipline to the next. As such, these articles offer the social-science or humanities researcher perspectives, tools, and responsible ways to expand the horizons of analyzing lived reality across various disciplines.
