Animal language

Certain animals use complex patterns to communicate with each other. These patterns have been called animal language. In many ways, they are similar to human language. That way, animal can use signing, or sounds. Sometimes, they use chemical compounds. Animal language has many of the same properties as human language:^[1]

• It is arbitrary. There's no relation between a sound or sign and its meaning.
• It is composed of small parts that are put together to form a message. These small parts are called morphemes.
• Language can be about things that aren't close by.
• The smallest units with meaning (the morphemes above) are composed of parts that have no meaning on their own.
• Users can produce and understand arbitrarily long messages
• Specific signs or sounds have a specific meaning.
