Linguaggi

Linguaggi is the plural form of linguaggio in Italian and denotes systems of signs used for communication. In everyday language it can refer to natural languages understood by communities as well as formal languages used in computing and logic.

In linguistics, linguistic study focuses on how languages encode and convey meaning through phonology, morphology, syntax, semantics, and pragmatics. Natural languages develop within communities over time and vary across regions, social groups, and contexts, while sharing underlying grammatical structures. They can change, die out, or be revived, and are often subject to standardization efforts and language policy.

Linguaggi naturali are the languages of human communication, such as Italiano, English, or Mandarin. They are typically categorized into families according to historical lineage (for example romance or germanic languages) and are studied for history, variation, and contact phenomena. Dialects, sociolects, and registers illustrate how a single linguistic system adapts to social and situational factors.

Linguaggi formali include programming languages, query languages, and markup or formal languages used to communicate with machines. They are designed with explicit syntax and precise semantics, enabling unambiguous instruction and processing by computers. Examples include Python, Java, C++, SQL, HTML and XML. These languages differ in paradigm (imperative, object-oriented, functional, declarative) and in domain of application.

Together, the concept of linguaggio and its plural linguaggi covers both human communication systems and formalized symbolic systems, highlighting how language structures enable meaning, information exchange, and technical specification across diverse domains.
