Structure (category theory) the morphisms are group homomorphisms: that is, of structures on one type, and mappings respecting that structure. Starting with a category "C" given abstractly, the challenge is to infer what structure it is on the objects that the morphisms 'preserve'. The term "structure" was much used in connection with the Bourbaki group's approach. There is even a definition. Structure must definitely include topological space as well as the standard abstract algebra notions. Structure in this sense is probably commensurate with the idea of concrete category that can be presented in a definite way — the topological case means that infinitary
