Sign language
A sign language is not a copy of a spoken language. For example, American Sign Language (ASL) and British Sign Language (BSL) are not copies of English. They are different from each other, even though they are both used in countries that speak English. Sometimes sign languages may copy a few elements from a spoken language, but usually they are very different. For example, sign languages often use different locations in space around the signer to represent people or objects that are being talked about. These locations are used like pronouns in spoken languages.
