Twitter help/languages



33 Languages are getting returned along with their language code using GET where as in 48 languages are available
Why the other 15 (48 Available Twitter languages from Account settings-33 returning from help/languages API) languages are not returning using the above API

And some language code excluding ‘Und’ ,language codes like ‘ta’ -> Tamil are being returned from Tweet object but the ‘ta’ is not present in help/languages

Some one please explain the reason and Solution for this
