humanlanguage

Human language, sometimes referred to in scholarly contexts as humanlanguage, is a system of communication shared by humans that is symbolic, generative, and rule-governed. It enables the expression of ideas, emotions, requests, and social relations through a potentially infinite array of messages. Language is typically vocal-auditory but also includes sign languages and written forms. Its defining features include recursion, combinatorial possibilities, and conventional meanings that are learned within a community.

Languages consist of distinct components: phonology (sound systems), morphology (word formation), syntax (grammatical structure), semantics (meaning), and pragmatics (contextual use). They can be spoken, signed, or written, and many languages have multiple modalities and scripts. Sign languages are full natural languages with their own phonology and grammar, not merely mimed or gestured versions of spoken languages.

Most children acquire language through immersion in a social environment, often developing rapid competence in their first language during early childhood. Bilingualism and multilingualism are common. Neurolinguistics studies show specialized brain regions for language, typically in the left hemisphere, and ongoing research explores how language is produced and understood in real time.

Human language varies across communities and evolves over time. Language families group related tongues, while dialects and sociolects reflect geographic, social, and cultural factors. Contact between languages can create pidgins and creoles, and writing systems introduce orthographic conventions that can diverge from pronunciation. Language change is constant and influenced by technology, media, and policy.

Scholars study language within linguistics, laboratories of cognition and neuroscience, and interdisciplinary fields such as psycholinguistics, sociolinguistics, and computational linguistics. Applications include language education, speech and language therapy, natural language processing, translation, and language preservation efforts for endangered communities.
