If anything can be said about the lost Paleo-European languages on the basis of what we find in the attested ones Basque, the Caucasian languages and Etruscan we can say that the Paleo-European were synthetic languages with rich inflectional morphology and diverse morphosyntactic alignments ( Basque and most Caucasian languages are ergative, Georgian split between accusative and active / stative, Etruscan is accusative ).
