1. Sign Structure:
* Handshapes: Many signs have different handshapes in BSL and ASL.
* Movement: The way signs are moved in space can vary considerably.
* Location: Where signs are made on the body or in space can differ.
2. Grammar:
* Word Order: The order of signs in a sentence can be different.
* Use of classifiers: These are signs that represent objects or actions, and their usage can differ.
* Use of facial expressions and body language: These play a crucial role in both languages, but the specific expressions and their meanings may vary.
3. Vocabulary:
* Many signs are entirely different: This is particularly true for signs related to culture, technology, and everyday objects.
* Some signs have similar handshapes but different movements or locations.
4. Origins and History:
* BSL: Developed independently of ASL, with roots in the deaf communities of Great Britain.
* ASL: Developed independently from BSL, with origins in French Sign Language and influences from Deaf communities in the United States.
It's important to note:
* Both languages are visually based, but not just "pictures" for words.
* Both have complex grammatical structures.
* Sign languages are constantly evolving, and new signs are created to represent new concepts.
In conclusion:
While there may be some similarities between BSL and ASL, they are distinct languages with their own structures and vocabularies. It's like comparing English and Spanish: they share some words and grammar concepts, but ultimately, they are different languages.
