German plural acquisition is influenced by noun productivity. Children learn high-productivity plural patterns faster than low-productivity ones, supporting a productivity scale for language development.
Area of Science:
- Linguistics
- Developmental Psychology
- Language Acquisition
Background:
- The acquisition of German plurals is complex and debated.
- Understanding factors influencing pluralization speed is crucial for language development theories.
Purpose of the Study:
- To investigate the role of noun productivity in the acquisition pace of German plurals.
- To determine if a productivity scale accurately predicts plural acquisition order.
Main Methods:
- Administered a plural elicitation task to 84 Viennese German-speaking children (aged 2;6 to 6;0).
- Analyzed the accuracy of elicited plural forms based on different pluralization patterns.
Main Results:
- Children achieved higher accuracy with high-productivity plural patterns (-e, -e+U, -er+U) compared to low-productivity ones (-s, -(e)n, pure Umlaut).
- A clear hierarchy of acquisition was observed, correlating with the degree of plural pattern productivity.
Conclusions:
- Noun productivity significantly impacts the speed of German plural acquisition.
- The findings support a productivity-based scale and are consistent with both single-route and dual-route language acquisition models.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
