Yes.  There exists a region on the dorsal surface of the temporal lobe
known as the planum temporale.  In most people, it is larger on the
left side than on the right; most people are also dominant for language
on the left side.  However, this is not a 100% correlation, but merely
a good indicator of linguistic dominance.
