The ditransitive verb-argument construction in German L1 Acquisition: A longitudinal case study

Usage-based approaches assume that children acquire grammatical constructions by linking form and meaning from ambient speech. Input shape is crucial in this process. One key construction type is verb-argument constructions (VACs), such as the ditransitive construction. Studies on the acquisition of English show that the verbs in VACs exhibit a Zipfian frequency distribution, with prototypical verbs occurring most often, facilitating learning.
This study extends the investigation to L1 German by analyzing the development of the ditransitive VAC in a dense corpus of a child’s speech (aged 2–5) and caregiver input. Results confirm a Zipfian distribution of the ditransitive VAC verbs in the input, supporting abstraction of VAC meaning. In his ditransitive VAC production, the child initially uses prototypical verbs expressing transfer but quickly expands verb variety, and coercion occurs from early on. This rapid development is linked to the child’s growing construction network, communicative needs, and familiarity with transfer event scripts.
