Which concept refers to the continuous range of languages used in interpreting?

The concept that refers to the continuous range of languages used in interpreting is known as the sign language continuum. This term illustrates the idea that sign languages do not exist in isolation but rather form a spectrum where variations occur based on regional dialects, social contexts, and individual styles. It highlights that sign languages can differ significantly, and a user of one variation may not fully understand a user of another due to these differences.

Understanding the sign language continuum is essential for interpreters because it impacts their approach to interpreting in diverse settings. They must be aware of these variations to effectively communicate across different sign languages and ensure accurate interpretation for all parties involved.

The other concepts, such as lexical equivalency, cross-cultural communication, and impartiality in interpretation, serve distinct roles in the field of interpreting. Lexical equivalency pertains to finding equivalent terms between languages, cross-cultural communication focuses on interactions between different cultures, and impartiality ensures that interpreters remain neutral and unbiased during the interpreting process. While all these concepts are important in interpreting, they do not specifically describe the continuous range of languages, which is what the sign language continuum encompasses.
