Morphological variation and development in a Northern Norwegian role play register

This paper investigates the variation in and development of a set of morphological variables in a register known to be used by Norwegian children when engaging in role play. In this register they code-switch to something resembling the standard or Oslo variety for their in-character role utterances. The variation across variables, subjects, and age is demonstrated and discussed, and although most variables are used in the standard variants, their rates vary. A fitted binomial generalised mixed effect analysis on the most frequent variables shows that the rate of standard variants increases significantly as an effect of age.
