The term “rapport” appears in literature with a striking diversity of meanings, ranging from the intimate to the formal. In novels like Charlotte Brontë’s Villette, it conveys a sense of mutual understanding or affinity between individuals ("I was conscious of rapport between you and myself" [1]), while in other works it is used more technically to describe formal reports or records, as seen in accounts and official documents during eras of political revolution ([2], [3], [4], [5], [6]). In sociological and psychological texts, notably those by Burgess and Park, “rapport” is discussed as a phenomenon of group dynamics, linking states of hypnosis, suggestion, and even the emergence of group consciousness ([7], [8], [9], [10], [11], [12], [13], [14], [15]). Meanwhile, French instructional texts employ “rapport” in various metaphorical and definitional senses—from describing proportional relations to conveying connections between concepts ([16], [17], [18], [19], [20], [21]). Even poets like Walt Whitman harness the term to evoke transcendent connections that bridge the personal and the cosmic ([22], [23], [24], [25]). This multifaceted application underscores how “rapport” has evolved in literary usage to encapsulate both empirical relationships and the more ineffable bonds of human experience.
