Why do you suppose that there are so many definitions of leadership?

Student answers may vary. They will likely include the idea that the term itself is taken from the common language and incorporated into the technical vocabulary of a scientific discipline. This appropriation carries extraneous connotations that create ambiguity of meaning. Additionally, researchers usually define leadership according to their individual perspectives and the aspects of the phenomenon that are of most interest to them. The differences in definition reflect deep disagreement about the identification of leaders and leadership processes.
