How does one speak about kinds in Norwegian? Which noun form should one use to say that dogs bark and cows are mammals? And is it always necessary to use a plural noun form to express genericity? The study presented in this book shows a cognitive approach to genericity in Norwegian. The study material includes three data sets--two surveys and a specialised corpus of generic texts. Both the surveys and the corpus were analysed in two ways--with the use of chosen cognitive models and with a number of statistical tests. Applying both qualitative and quantitive methods has allowed to conduct a comprehensive study on genericity in Norwegian.
