Through an in-depth case study of humour concepts in Danish, the chapter develops a cultural-semantic analysis of the untranslatables of laughter, and provides a new account of the worldview engendered by such words. The Danish language of laughter is particularly rich in synaesthetic humour metaphor; the chapter sets out to explicate key categories within this class: sort humor ‘black, murky humour,’ plat humor ‘flat, plain humour,’ fed humor ‘fat humour,’ and tør humor ‘dry humour.’ The analysis is undertaken within the Natural Semantic Metalanguage (NSM) framework of analysis and takes an explicitly translational approach to language, culture, and worldview. Providing a roadmap for how to navigate in the landscape of translatables and untranslables, the chapter contributes to both translational semantics and linguistic worldview studies.
