A visual language that serves as the predominant sign language of Deaf and hard of hearing communities in anglophone Canada (note there are other types of sign language including Maritime Sign Language, used by some here in Nova Scotia). The shape, placement, and movement of the hands as well as facial expressions and body movements all play important parts in conveying information and meaning. ASL has the same linguistic properties as spoken languages, but the grammatical structure and syntax differ from English. Like all languages, ASL grows and changes over time.
