In this paper I present a study of language death from a linguistic perspective. Starting with an examination of the changes which are found in languages with a weakened linguistic structure, I then focus on changes round by compating different types of spakers from South Western varieties of Basque. Consequently, I analyse the main linguistic change trends that South Western varieties of Basque have in common with weakened languages. I have paid particular attention to an aspect which has not been the object of much research in previous work in this area, namely the direction of change in weakened languages. For this purpose, I have taken into account the maintenance and loss hierarchies which are predicted for linguistic changes and the different directions of change which are manifest in these hierarchies.
