The study of child language has its high time during this decade. The original boom set upby the Chomskyan conception of the child äs a little ünguist and the resulting mass of longitudinal data and formal grammars in the sixties had later been extended to let semantic-cognitive models and communicative approaches into the field y too.This thematic section is an attempt to provide a picture about the various approaches to child language äs used in European countries. The image is by far not intended äs anexhaustiveone, however. Not only are languages missing -due to a lack of incoming papers from colleagues we have approached -but the communicative framework is almost entirely missing. Our ambition was only to provide a picture of child language studies concentrating on grammar.Even within the limited scope of this volume some features characteristic of contemporary child language research can be discerned in the volume. The paper by Pacesova shows that the traditional longitudinal method is still with us and it can give interesting insights concerning less well studied languages. The main trend, however, äs the papers by Chipman and Francavilla, Schaner-Wolles and Pleh, Komlosy and Ackermann show, is the use of experimentation. Experimental data are becoming important concerning cross-linguistic comparisons, äs both the review article by Schaner-Wolles and the paper by Chipman and Francavilla show.Experimental results are interpreted today both with reference to grammatical models and to possible processing principles (Schaner-Wolles).

This might be expected in view of the fact that -at the earliest stages of language development -the labelling of persons and objects is most frequent way of communication and the vast majority of dialogues consistsof thequestions "who is it" or "what is it", the answer being, both on the part of the child and the adult, naturally, the noun in nominative singular. As for the phonemic shape, however, only those forms which are regulär and lucidly marked äs for gender were in agreement with adult forms. This suggests that the child is more sensitive to regularity than to frequency of the heard models. Hence the explanation äs t o why the nominative singular, in spite of its high frequency, had so many deviated forms and also for the child's preference of diminutives, i.e. the onomasiological category which closely corresponds to his hypothesis on word structure, viz. unification of the Suff...
