nwymiarowym
nwymiarowym is the instrumental singular masculine form of the Polish adjective n-wymiarowy, meaning “n-dimensional.” The standard construction combines the numeral n with the adjective wymiarowy to describe objects, spaces, or models that involve a certain number of dimensions. In formal writing the hyphenated form n-wymiarowy is typical, and its inflected instrumental form is n-wymiarowym; in practice you may encounter the variant nwymiarowym when hyphens are omitted, though this is less standard.
In mathematics and related disciplines, n-wymiarowy describes spaces, coordinates, or objects that require n independent parameters
Usage notes: the term is gender- and case-sensitive like other Polish adjectives. It agrees with the noun
