Abstract
In the present paper bound usage of morphemes was regarded as morpheme-based word- formation and free usage of morphemes – as morpheme-based phrase formation. The quantitative relation between these 2 usages, denoted as “M-combination” and “W-combination” respectively, was measured by number of types of morphemes to which stems are attached. This analysis was carried out by choosing 50 high frequency loanword stems, found in “Mainichi Newspaper” Corpus in all articles published in 2006. Number of Types of M-combinations and W-combinations that these stems form with Sino-Japanese and loanword stems, were counted. Then the relation between 2 usages of chosen stems, divided into 2 groups (head usage and non-head usage), was analyzed with 3 parameters: correlation coefficient, similarity of co-occurring stems, difference coefficient of co-occurring stems.
