Neperdirbti

Neperdirbti is a Lithuanian word formed by adding the negation prefix ne- to the verb perdirbti, which means to process or refine. The term is used as an adjective or in analytic phrases to describe materials or products that have not undergone processing, transformation, or refinement. It denotes a raw, natural, or unrefined state, in contrast to items that have been processed.

In everyday and industrial usage, neperdirbti is common across sectors such as agriculture, food, mining, and construction. Examples include neperdirbti grūdai (raw grains), neperdirta žaliava (raw material), and neperdirbta medžiaga (unprocessed material). The term is frequently used to distinguish stock in its initial form from finished goods, for example in procurement, logistics, and quality control. It may also appear in environmental and sustainability discussions to emphasize natural or untampered substances.

While not a technical standard by itself, neperdirbti helps communicate expectations about processing needs, storage, safety, and potential treatment before use. Understanding the term requires attention to context and agreement about what constitutes processed in a given industry.

Etymology: from the ne- prefix plus perdirbti (to process).
