kraftigste
Kraftigste is a linguistic term referring to the superlative form of the adjective kraftig in several Scandinavian languages, meaning the strongest or most powerful. The stem kraft- comes from a root meaning power or strength, combined with the adjective suffix -ig to yield kraftig, “strong.” To express the highest degree, the superlative is formed with language-specific endings: in Swedish the common form is kraftigaste; in Danish and Norwegian, variations exist, including kraftigste and kraftigst depending on dialect and orthographic standards. The exact spelling and inflection can vary, and some dialects or older texts may use different morphologies.
