While both are visual languages used by deaf and hard of hearing communities, they have distinct:
* Sign vocabulary: Many signs have different meanings or are signed differently.
* Grammar: The structure of sentences and the use of grammatical markers differ.
* Regional variations: Both languages have regional variations, with different dialects used in different parts of their respective countries.
Think of it like the difference between English and Spanish. They are both languages, but they use different words, grammar, and have different regional dialects.
Auslan and ASL are separate languages with their own unique systems and structures.
