### Noun[edit]

**morphism** (*plural* **morphisms**)

- (mathematics, category theory) (
*formally*) An arrow in a category; (*less formally*) an abstraction that generalises a map from one mathematical object to another and is structure-preserving in a way that depends on the branch of mathematics from which it arises.**1982**, Israel Program for Scientific Translations (translator), Lev J. Leifman (editor of translation), N. N. Čencov,*Statistical Decision Rules and Optimal Inference*, American Mathematical Society, Translations of Mathematical Monographs, Volume 53, page 50,- 1°
*The composition of two***morphisms**is defined if and only if the final object of the first**morphism**is the initial object of the second. This composition is also a**morphism**, whose initial object is the initial object of the first**morphism**and whose final object is the final object of the second.
