What does morphology study?

So, morphology as a branch of linguistics studies the forms and structure of words. But there is also biological morphology, which studies the external form and internal structure of the organism. Plant morphology is a branch of botany that deals with the patterns of structure and processes of plant formation. Human morphology is a section of anthropology. Mathematical morphology, which deals with the study of geometric structures from the point of view of set theory, topology, and random functions, stands completely apart. [eight] .
