Language, traditionally studied from linguistic and cognitive perspectives, can also be formalized as a physical system constrained by energy, entropy, and information. We propose Linguistic Physics, a unified framework interpreting language as an emergent, energy-constrained, and dynamically evolving system. This perspective integrates information theory [1]–[3], statistical mechanics [4], dynamical systems [5], and cognitive neuroscience [6], [7] to model phenomena such as compression, ambiguity, entropy regulation, semantic topology, phase transitions, alignment, evolution, creativity, multimodal emergence, hyper-language structures, and socio-cultural dynamics. We outline theoretical foundations, methodological strategies, and potential contributions, providing a roadmap for computational, experimental, and AI applications.
