language

The preferred language used to return results. The value must be a valid BCP 47 language tag, for example, en for English.

This setting affects the languages used in the results, but not the results themselves. If no language is specified, or not supported for a particular result, the partner automatically chooses a language for the result.

For an example, we'll use the Greek language. You search for Athens, Greece, with the language parameter set to en. The result found will most likely be returned as Athens.

If you set the language parameter to el, for Greek, then the result found will more likely be returned as Αθήνα.

If the data provider does not have a value for Greek, the result will be in a language that the provider does support.
