ABSTRACT
Consider the following two parallel paradigms, from English and Basque respectively:
(1) a.Mary left
b.Mary didn't leave
c.*Mary did leave
d.Mary did leave
a.Mari joan da Mary left has 'Mary has left'
b.Mari ez da joan Mary not has left 'Mary hasn't left'
c.*Mari da joan Mary has left ('Mary has left')
d.Mari da joan Mary has left 'Mary has left'
Examples (la) and (2a) both illustrate declarative sentences from English and Basque. The English sentence has a single inflected verb. The Basque sentence shows a non inflected lexical verb followed by an inflected auxiliary.
