Taking a micro-comparative approach within Romance null subject languages
(NSLs), I argue that considerable cross-linguistic variation in the
distributions of null subjects can be attributed to differences in the
featural composition of overt subject pronouns. This will let us address
the competition between *pro* & overt subject pronouns in NSLs in terms of
Schlenker's (2005) pragmatic principle *Minimize Restrictors!*. This has an
empirical advantage over the standard analyses of variation between NSLs,
which overpredict categorical syntactic differences in the availability of
*pro* in different NSLs.
