It is
Vennemann's contention that Proto-Vasconic did
once have initial clusters and
that eg. *sCV- > zV-
==============
A.F
What examples
can you give ?

that PIE *l and *r are reflected as [s] written -z- in Bask.

:

Where did that come
from?
=============
A.F
I suppose the lateral [l] and vibrant [r]
gradually became lateral fricative[lsh],
the lateral component was lost,
the fricative feature became prevalent
and finally merged with s.
This process made room for *(n)d >
Bask l
and *(n)t? > r
The basic comparative rule is simple :
Bask l or r can never correspond to l or r in PIE.
Any similarity points immediately toward
borrowing.
