Chapter 3 presents an updated version of the tense system of Verkuyl (2008) organized on the basis of the three binary oppositions. The update is needed in view of a number of improvements – substantively and notationally – due to later work. The main ingredient of this chapter is the strict distinction between the notion of present domain and the notion of the fleeting point ??, which has a counterpart in the distinction between past domain and then-fleeting point ??’. The parallelism in a binary tense system is argued to be a dominant force in its organization.
