Final answer:
Languages that form between different societies when they need to communicate are called pidgins. These simplified languages can evolve into Creoles if used by a community as a first language.
Step-by-step explanation:
Languages that form when different societies come into contact and they must devise a system of communication are called pidgins. A pidgin language develops as a means of communication between speakers of two different languages. Pidgins are simplified languages with elements taken from both original languages, typically with reduced vocabularies and grammatical structures. Over time, if a pidgin becomes established as the native language of a community, it may become a Creole. Creoles differ from pidgins in that they have more complex structures and are used as first languages within communities.
As societies interact more frequently and globally through technology and travel, the dynamics of language evolution and the ways in which people communicate continue to change. However, with globalization, there is a fear among linguists and cultural anthropologists that many minority languages are being abandoned in favor of more dominant languages, leading to a loss of linguistic diversity.
