This phenomenological research aimed to illuminate the nature and effects of ordinariness in nursing and to discover whether the phenomenon enhanced the nursing encounter. The researcher worked as a participant observer with six registered nurses in a Professorial Nursing Unit. Following each interaction, the researcher wrote her impressions in a personal-professional journal and audiotaped conversations with the respective nurses and patients to gain their impressions. Using a theoretical framework of the phenomenological concepts of lived experience, Dasein, Being-in-the-world and fusion of horizons as an underpinning methodology, an initial hermeneutical analysis and interpretation of the impressions generated qualities and activities indicative of the aspects of the phenomenon of ordinariness in nursing. The second phase of the analysis and interpretation sought to illuminate the nature of the phenomenon itself. Eight actualities of the nature of the phenomenon emerged: 'allowingness,' 'straightforwardness,' 'self-likeness,' 'homeliness,' 'favourableness,' 'intuneness,' 'lightheartedness' and 'connectedness.' These actualities were described in relation to the phenomenon of interest. The effects of the phenomenon were the creative potential to enhance the nursing encounter and included many and various effects of facilitation, fair play, familiarity, family, favouring, feelings, fun and friendship. The research found that nurses and patients shared a common sense of humanity, which enhanced the nursing encounter. Within the context of caring, the nurses were ordinary people, perceived as being extraordinarily effective, by the very ways in which their humanness shone through their knowledge and skills, to make their whole being with patients something more than just professional helping. The shared sense of ordinariness between nurses and patients made them as one in then- humanness and created a special place, in which the relative strangeness of the experience of being in a health care setting, could be made familiar and manageable.
