fyrtrådig

Fyrtrådig is a Swedish adjective meaning four-threaded or consisting of four threads or strands. It is formed from fyr (“four”) and tråd (“thread”) with the adjectival suffix -ig. The term is primarily used in technical contexts such as textiles, yarn production, and ropework, where it denotes a construction made from four separate strands rather than a single strand or other multi-ply arrangements.

In practice, fyrtrådig appears in product specifications and historical descriptions to describe yarns, cords, and ropes. Examples include fyrtrådig garn (four-stranded yarn) and fyrtrådig rep (four-strand rope). The concept can also be applied in weaving or fabric construction to indicate that the material is formed from four distinct thread groups. In maritime and industrial literature, the term helps distinguish rope and cord types by their internal strand count.

Usage notes: fyrtrådig is a technical term and is most commonly found in catalogs, trade literature, and historical texts rather than in everyday speech. It may be encountered alongside related terms such as flertrådig (multi-threaded) or other strand-count descriptors like tvåtrådig or trestrådig, which indicate two- and three-stranded constructions respectively.
