Forma

Forma is a term of Latin origin meaning form or shape, used across disciplines to denote structure, configuration, or typology.

In botany, forma (plural formas, abbreviated f.) is a taxonomic rank below variety, used for minor, heritable differences within a species, such as color or habit. Its use varies by code and authority; some systems include it as a formal rank, others treat it as informal. In plant pathology, forma specialis describes a pathogen form defined by host range.

In philosophy and aesthetics, forma denotes the essential structure or organizing principle of a thing; in Aristotle's hylomorphism form actualizes matter. In art and design, form refers to arrangement, proportion, and composition.

In linguistics and everyday language across Romance languages, forma means form and appears in phrases like forma de pago.

The term also appears in cultural and brand names. Across contexts, forma commonly signals configuration, structure, or typology.
