Morphology is the scientific study of the form and structure of living organisms and their parts. In biology, morphological analyses examine shape, size, and arrangement of features, linking form to function, development, and evolutionary history. It covers both macroscopic anatomy and microscopic organization such as tissues and cells.

Key concepts include homologous structures, which arise from a common ancestor, and analogous structures, which serve similar functions but do not share ancestry. Ontogeny and phylogeny describe development within an individual and the evolutionary relationships among species. Morphologists also study variation in form through allometry, sexual dimorphism, and quantitative shape analysis, often using morphometrics.

Methods range from comparative anatomy and paleontology to contemporary imaging, dissection, and geometric morphometrics, supported by statistical approaches. Morphology contributes to systematics, functional morphology, and the reconstruction of ancestral states, and is routinely integrated with genetics, developmental biology, and ecology.

In linguistics, morphology is the study of the internal structure of words and the rules for combining morphemes, the smallest units of meaning. It distinguishes free morphemes from bound morphemes and analyzes inflection, derivation, and compounding. Morphological study interacts with phonology and syntax and reveals crosslinguistic variation in word formation.

The term morphology combines Greek morphe “form” and -logia “study” and has applications across sciences, including biology and linguistics.
