This study was made to clarify the meaning of the ‘noun+ナ+noun’ (hereinafter called ‘N1+ナ+N2’) construction, in which a derivational suffix is made by adding ‘ナ’ to nouns such as ‘ワインな氣分’, ‘大人な對應’, and also to investigate the similarities and differences between ’N1+ナ+N2’ and ‘noun+ノ+noun’ (hereinafter called ‘N1+ノ+N2’) and between ‘N1+ナ+N2’ and ‘-的(-teki)’.
The semantic features include a prototypical appearance of ‘attribute’. It is further categorized into ‘prototypical N1+ ナ’(ex.大人の、大人な對應), which describes the element that fits into the base N1 category, and ‘metaphorical N1+ナ’, which describes the element that does not fit into the base N1 category(例:子供の、大人な對應). Moreover, there exists a form ’N1+ナ+N2’ in which ’pragmatical inference’ is needed because of its context-dependence.
As for the contrast ‘N1+ナ+N2’ with ’-的’, which indicates that it has ‘attribute’ in common. However, the point is whether ’pragmatic inference’ is needed or not. On the other hand, through the contrast of ’N1+ナ+N2’ with ’N1+ノ+N2’, it was found that they both require the attribute and pragmatic inference, but while ‘N1+ナ+N2’ prototypically indicates the attribute, ‘N1+ノ+N2’ prototypically indicates N1 as a concrete concept, and peripherally as the attribute. Also, the pragmatic inference needed for 「N1+ナ+N2」 tends to rely more on context than 「N1+ノ+N2」 for its construction which broadens its semantic realizations.
