The purpose of this paper is to review the concepts of anxiety, angst and stress, and to define the linkages between them (specially anxiety-angst, on one hand, anxiety-stress, for other); also, it is sought to identify several key elements that allow to differ among these concepts. In order to carry out this purpose, we offer a general introduction to conceptual confusion has taken place around this terms, contributing empirical evidences by themselves, and reflecting the current approach. Next, we follow a similar structure for the three concepts: (1) an introduction, (2) a historical review on each one of them (picking up definitions from many sources), and (3) a section dedicated to the different conceptual frameworks, serving us as the contributions of different disciplines as Psychology (including theoretical approaches as behavioral, cognitive-behavioral, psychodinamic), Philosophy, Psychoanalysis, Physics, and many others. Finally, we develop some conclusions, and suggest future directions for building research.
