ISO 639-1 standard language codes
These codes are a useful international and formal shorthand for indicating languages. Many multilingual web sites use these codes to prefix URLs of specific language versions of their web sites. Two-letter country-specific top-level-domain code suffixes are often different from these language-tag prefixes.
