We describe the derivations in a pregroup grammar as the 2-cells of a free compact 2-category defined by the grammar. The 2-cells of this category are the intermediary parsing structures necessary for a semantic interpretation when pregroups are used in natural language processing. The construction of the free compact 2-category also provides another cut-free axiomatisation of compact bilinear logic.
