1. The Spectrum of Sign Language Variation:
* This interpretation views sign languages as existing on a continuum of variation, from very closely related to spoken languages (like signed languages used within the deaf community of a particular country) to more distinct and independent languages with their own grammatical structures and linguistic features.
2. The Relationship Between Sign Language and Spoken Language:
* This view suggests that sign languages aren't simply "visual" versions of spoken languages. They have their own unique properties and are often influenced by the spoken languages of their users but also develop independently. The continuum reflects the varying degrees of this influence and independence.
3. The Development of Sign Languages Over Time:
* Some researchers believe that sign languages evolve along a continuum. They may start as simple systems of gestures and then become more complex over time, developing their own grammatical rules and vocabulary, ultimately becoming distinct languages.
4. The Interplay of Sign Language and Spoken Language:
* This interpretation highlights the ongoing interaction between sign languages and the spoken languages of their users. The continuum reflects how these languages influence and shape each other, leading to ongoing changes and development.
Examples of the Sign Language Continuum:
* Signed languages like American Sign Language (ASL) or British Sign Language (BSL) are considered relatively independent languages with their own grammatical structures and vocabulary.
* "Contact Sign" or "Fingerspelling" are systems used by deaf people in countries where a formal sign language doesn't exist. These systems rely heavily on the spoken language and fingerspelling of the alphabet.
* Sign Languages used within families or smaller communities can be more rudimentary and rely on gestures and miming, with less complex grammatical structures.
It's important to note:
* The concept of a sign language continuum is not a clear-cut categorization, and there are debates about the specifics of the relationship between sign languages and spoken languages.
* The continuum is more of a conceptual framework for understanding the diversity and complexity of sign language development and usage.
Ultimately, understanding the sign language continuum can help us appreciate the rich tapestry of sign languages worldwide and recognize the unique linguistic abilities and cultural expression they represent.
