From co- +‎ span.

Noun

cospan (plural cospans)

1. (mathematics) The dual of a span.
   • 2016, Kenny Courser, “A bicategory of decorated cospans”, in arXiv‎^[1]:

     This extra structure arises from a lax symmetric monoidal functor $F\colon \mathbf {C} \to \mathbf {D}$; we use this functor to "decorate" each cospan with apex $N\in \mathbf {C}$ with an element of $F(N)$.
