Halvfast

Halvfast is a term used in Scandinavian languages to denote something that is only partly fixed. It typically appears in technical, architectural, and contractual contexts to describe conditions or components that are not fully rigid or permanent.

Etymology and usage notes: The word is a compound of halv meaning "half" or "partially" and fast meaning "fixed" or "firm." In Norwegian, Swedish, and Danish contexts the term conveys partial fixation, with cognates across the North Germanic language family. In English-language texts, halvfast is often rendered as "semi-fixed" or "partially fixed," depending on context.

Applications and contexts: In engineering and construction, halvfast can describe mounting arrangements or supports that allow limited movement or adjustment while remaining anchored. In contracting or procurement, halvfast may describe price elements or terms that are fixed for a portion of the contract and variable for another portion. In everyday language, it can be used more loosely to describe plans or arrangements that are not wholly fixed, for example when details are still subject to change.

Regional usage: The term is most common in Norwegian and Swedish contexts, though cognates exist in other Nordic languages. Its precise sense may vary by sector and country, so interpretation often depends on the surrounding technical or legal vocabulary.
