topos (plural topoi or toposes)

1. A literary theme or motif; a rhetorical convention or formula.
   • 2003, Roy Porter, Flesh in the Age of Reason, Penguin (2004), page 239,

     The ritual of weighing the soul was an iconographic topos familiar to Christianity from the ceremony of the weighing of sins at the Last Judgement.

2. (category theory) A Cartesian closed category which has a subobject classifier.
   • 2011 June 27, Tom Leinster, “An informal introduction to topos theory”, in arXiv.org‎, Cornell University Library, retrieved 2018-03-30:

     Now in a topos, you can interpret a really vast range of theories: any ‘higher-order theory’, in fact. (First order means that you can only quantify over elements of a set; in a second order theory you can also quantify over subsets of a set; and so on.) Models of any such theory get along well with logical morphisms, because logical morphisms preserve everything. So you can tell a similar story for toposes, logical morphisms and higher order theories as for finite product categories, finite-product-preserving functors and algebraic theories.
