Definition 7.40.2. Let \mathcal{C} be a site.
We say an object U of \mathcal{C} is weakly contractible if the equivalent conditions of Lemma 7.40.1 hold.
We say a site has enough weakly contractible objects if every object U of \mathcal{C} has a covering \{ U_ i \to U\} with U_ i weakly contractible for all i.
More generally, if P is a property of objects of \mathcal{C} we say that \mathcal{C} has enough P objects if every object U of \mathcal{C} has a covering \{ U_ i \to U\} such that U_ i has P for all i.
