The term stance-taking  is one of the most enigmatic concepts in linguistics due to the great number of definitions and categorizations introduced to analyze it. This paper aimed at reviewing previous research on stance, and pinpointing the gaps that need to be bridged, thus the method used is the analysis of the definitions and methods presented in the literature. The findings showed that defining stance relies on the objectives of research and the methods adopted for the analysis. Also, analyzing stance in casual conversations was found to be a gap in the literature.
