A language tag is a standardized code used to identify a specific language or dialect in digital communication. It typically follows the format defined by the IETF (Internet Engineering Task Force), which includes a primary language code, and may also include subtags for regional variations or specific scripts. For example, the tag "en-US" represents American English, while "fr-CA" denotes Canadian French. Language tags are essential for ensuring that content is displayed correctly for users in different linguistic contexts. They help software applications, websites, and databases to serve the appropriate language version, enhancing accessibility and user experience. By using language tags, developers can create more inclusive digital environments.
