The advantages of this approach include its comprehensibility, pedagogical applicability and its adaptability in terms of the natural acquisition theories of language, such as different usaga-based models. This paper discusses the clause types of learner Finnish and the phenomenon of mixing up features of several clause types in one actual sentence. The phenomenon of mixing up the features of different clause types is typical in native-speakers¡¯ Finnish but is also a source of unidiomatic structures of learner Finnish. The existential sentence of Finnish serves as basis for this observation. %K learner language %K corpus research %K syntax %K syntactical clause types %K existential sentence %K Finnish as a second language %U http://dx.doi.org/10.5128/LV21.03
