• In large parts of the world, the official language is not even the language actually spoken today in the largest part of the country.
  
  
• Where the official language is a foreign language or a relatively new language developed from a lingua franca (#172), the official language is the language of just a few toponyms, or even none at all.
  
  
• In that case, the toponyms have been created in local vernaculars, whether these were considered a language, a dialect, or a sub-dialect.
