That's the POSIX Locale Name standard that incorporates country and
optionally script.  The languageList() returns the preferred list of
languages the user has selected and it's almost certain you don't want
to be using that directly.  If you do need to extract the language
code only from the locale name then you need to use
QLocale::splitLocale() to separate the language name out.

If you're just wanting a translation into the users preferred locale
language of any language name then you want
KLocale::languageCodeToName().
