Most languages not in Europe. Finnish, Estonian and Hungarian
and other Uralic languages are not indo European languages in
origin. Persian, and languages developed from Sanskrit (ie Hindi,
Urdu, Bengali, punjabi etc.) ARE indo-European. Maltese is not.
Telugu, Kannada, and Tamil are Indian languages that are Dravidian,
not related to Sanskrit. You weren't very specific so this is the
best I can do, sorry.
