A (2,1)-presheaf is a presheaf with values in the (2,1)-category Grpd. A 2-truncated (∞,1)-presheaf.
Sometimes this is also called a prestack. Other times a prestack is more specifically taken to be a separated (2,1)-presheaf: a -presheaf such that the functors into its descent objects are full and faithful functors.
The ∞-stackification of a -presheaf is a certain 2-sheaf or stack.
