This article analyzes functions and processes of research conceptualization. The most prevailing limitation of nursing research, as represented in its published literature, concerns the relevant use of knowledge and logic for the formulation of that which is to be studied. To that end, the components of the conceptual phase of research, as they develop progressively from the initiating question through the stipulation of the specific purpose of a study, are discussed. For each component emphasis is given to the function served by past knowledge toward the generation of new knowledge.
