Our aim is to discuss language strategies of a trilingual child, who uses Estonian, Finnish and Norwegian on a daily basis. Especially, we focus on the influence of the Finnish language on the Estonian language used by our informant. Estonian and Finnish are closely related languages, and they both have rich morphological system. We argue that the interaction between morphologically rich inflectional systems is diff erent than the interaction between morphologically very different systems. Our informant speaks Estonian with her mother and brother and Norwegian with her father. She lives in Finland, and Finnish is her school language as well as the language of many daily situations. At the time of collecting the data, she was 10 years old.
