Interlinguistics

human language whose phonology, grammar, and vocabulary have been consciously devised for human or human-like communication

language used to facilitate communication between groups without a common native language

A pidgin , or pidgin language, is a grammatically simplified form of contact language that develops between two or more groups of people that do not have a language in common: typically, its vocabulary and grammar are limited and often drawn from several languages. It is most commonly employed in situations such as trade, or where both groups speak languages different from the language of the country in which they reside (but where there is no common language between the groups).

language meant for communication between people from different nations who do not share a common first language

deliberate effort to influence the function, structure, or acquisition of languages or language variety within a speech community

discipline that studies communication across different cultures and social groups, or how culture affects communication

Interlinguistics, also known as cosmoglottics, is the science of planned languages that has existed for more than a century. Formalised by Otto Jespersen in 1931 as the science of interlanguages, in more recent times, the field has been more focused with language planning, the collection of strategies to deliberately influence the structure and function of a living language. In this framework, interlanguages become a subset of planned languages, i.e. extreme cases of language planning.

Intercomprehension is when people try to communicate with each other using their own different languages. Intercomprehension can be explained as a dialogue between people from two different languages. Each one expresses in their own language, making efforts to understand each other.
