Remark 81.5.1. In Situation 81.2.1 let $X/B$ be good. Let $Y \subset X$ be a closed subspace. By Remarks 81.2.2 and 81.2.3 there are $1$-to-$1$ correspondences between

  1. irreducible components $T$ of $|Y|$,

  2. generic points of irreducible components of $|Y|$, and

  3. integral closed subspaces $Z \subset Y$ with the property that $|Z|$ is an irreducible component of $|Y|$.

In this chapter we will call $Z$ as in (3) an irreducible component of $Y$ and we will call $\xi \in |Z|$ its generic point.
