Preference for linking element -en- in Dutch noun-noun compounds: native speakers and second language learners of Dutch

In Dutch, variation occurs in the formation of noun-noun compound words. Some compounds always add the linking element -en- between the two nouns; some compounds never use such a linking element; and still others allow both options. The element -en- is homophonous with the regular plural ending in Dutch, and we therefore investigated if plural semantics creates a preference for the linking element -en- in novel Dutch noun-noun compounds. We also investigated if the preference for linking -en- is influenced by just meaning (i.e., a semantic plural), form (i.e., a formal plural), or perhaps both. The influence of native language on preferences for Dutch compounds was also investigated. In study 1, we tested native speakers of Dutch; in study 2, Frisian-Dutch bilinguals; and, in study 3, speakers of German with Dutch as a second language. Plurality played a role in the preferences for Dutch compound formation in all tested groups. For native speakers of Dutch, Frisian, and German, moreover, the preference for a linking element in novel Dutch compounds was influenced by both the semantic plural and the formal plural. However, these effects were smaller for the native speakers of German. These findings confirm the findings of earlier studies (e.g. Schreuder et al. in Language and Cognitive Processes 13(5):551–573, 1998) showing linking -en- to carry an intrinsic plural meaning. Kiparsky’s level-ordering hypothesis (Linguistics in the morning calm, pp. 3–91, 1982) and Pinker’s words-and-rules theory (Words and rules: the ingredients of language, 1999) are re-considered in light of the present findings.
