A collostructional approach to Japanese noun-modifying clause construction use and acquisition: a learner corpus study

Japanese features a general noun-modifying clause construction (NMCC) with a more versatile range of semantic and pragmatic interpretations than equivalent constructions in other languages. Motivated by the learning challenge NMCCs pose to Japanese as a foreign language (JFL) learners, this article examines speech data from the International Corpus of Japanese as a Second Language (I-JAS) to compare learner use of NMCCs against a large L1 Japanese corpus. Instances of the construction from both corpora were analyzed to identify high-frequency part-of-speech categories and subcategories in the modifying clause predicate and head noun slots. A simple collexeme analysis was then employed to identify strongly attracted and repelled lexical items among those identified in realizations of the construction. Taken together, findings from these analyses revealed an important connection between the semantic weight of head nouns in NMCCs and the idiomaticity of the construction, with learner productions demonstrating a tendency toward heavy head nouns. This study lays the groundwork for future research seeking to explore the NMCC at different levels of granularity and to improve its treatment in JFL pedagogical materials.
