The issue of understanding and modeling vagueness was already addressed by many authors, especially in the second half of the XXieth century. In this paper, we try to provide an organized discussion of different categories of vagueness, pointing out circumstances where they appear. They all lead to a trichotomy of the universe of discourse, which seems to be the common feature of the different forms of vagueness. Basic representations frameworks are proposed for each case. The paper does not advocate a particular view against others but rather identify the characteristic features of each situation.
