Are spatial terms rooted in geometry or force-dynamics? Yes

Area of Science:

• Cognitive Science
• Linguistics
• Semantics

Background:

• Spatial term meaning is often explained by geometric properties (e.g., 'on' implies vertical alignment).
• However, geometric features alone are insufficient to explain the nuances of many spatial expressions.
• Force-dynamic properties (e.g., support, containment) are increasingly recognized as crucial.

Purpose of the Study:

• To argue for a dual approach integrating both geometric and force-dynamic properties for understanding spatial terms.
• To propose that spatial terms can be divided into two distinct sets based on these properties.
• To explore the consequences of this division for language acquisition, variation, and cognition.

Main Methods:

• Conceptual analysis of existing theories on spatial term meanings.
• Argumentation based on linguistic examples and literature review.
• Exploration of implications for cognitive and linguistic research.

Main Results:

• Spatial terms are not solely defined by geometry; force-dynamics are essential.
• Spatial terms can be categorized into two groups: geometric and force-dynamic.
• This dichotomy impacts understanding of language acquisition, cross-linguistic variation, and pragmatic principles.

Conclusions:

• A comprehensive understanding of spatial terms necessitates integrating both geometric and force-dynamic properties.
• The proposed two-set division offers a framework for analyzing spatial language differences and similarities across languages.
• This framework may have implications for cognitive systems and their neural bases.
