Langues refers to a family of languages that are primarily spoken in the regions of Southeast Asia and Pacific Islands. These languages are known for their unique phonetic structures and grammatical features, which often differ significantly from those of Indo-European languages. The term can also refer to the study of languages in general, encompassing various aspects such as linguistics, syntax, and semantics. This field explores how languages are structured, how they evolve over time, and how they are used in communication across different cultures.
