Language Advocacy is a movement that seeks to promote the importance of language learning and understanding in today's multicultural world. It aims to create awareness about the benefits of multilingualism and the positive impact it can have on individuals, communities, and even economies.

"Languages of limited diffusion" (LLDs) refer to languages that have a relatively small number of speakers and are not widely spoken or distributed in comparison to major world languages. These languages often have limited geographic, cultural, or ethnic reach and may not be widely understood outside specific communities or regions. Languages of limited diffusion are typically at risk of declining or disappearing as speakers assimilate into larger linguistic communities or as a result of cultural changes.

The term is often used in the context of language policy and linguistic diversity efforts, highlighting the need to preserve and support languages that are spoken by smaller populations. Governments, organizations, and advocates may work to address the challenges faced by speakers of languages of limited diffusion, implementing policies and initiatives to promote their survival and vitality.

A workers' cooperative is a type of business organization owned and democratically controlled by its employees.

Each worker typically has an equal say in the decision-making, regardless of their position or level within the organization.

A community interpreter bank refers to a system or organization that facilitates access to language interpretation services within a community.
