Crudus

Crudus is a Latin adjective meaning raw, crude, rough, or coarse. In classical Latin, it described materials, methods, or manners and could be used metaphorically to indicate a lack of refinement or polish. The term has carried into modern scholarly and scientific usage as a descriptor in various fields, often signaling something in an undeveloped, unpolished, or rugged state.

Grammatically, crudus follows the pattern of standard second-declension adjectives. The masculine singular is crudus, the feminine singular cruda, and the neuter singular crudum; the forms agree with the noun they modify. In English translations it is commonly rendered as crude or raw, depending on the context.

In taxonomy and biology, crudus has appeared as a Latin species epithet in some historical and contemporary names, typically to indicate rough texture, coarse morphology, or a crudely formed feature. It is one of many Latin descriptors used in scientific names to convey appearance or character rather than to define a distinct biological category.

In scholarly Latin and in translations of classical texts, crudus also appears in phrases and glossaries to convey unrefined or elemental states. While it is not a modern technical term with a single domain of use, crudus remains part of the historical vocabulary that informs Latin description across disciplines.
