I have some in my Azak, as roots morphology obliges roots to have at least
a final consonnant, but nothing before is mandatory (Azak is heavily
agglutinating with only suffixes and words used without at least one suffix
are very rare (mostly interjections)). The most important consonnantal root
is 'n'. It is used to transform some suffixes into nouns or verbs (like
person suffixes into pronouns) and is widely used.
Also, doesn't Euskara have also consonnantal roots, especially with verbs?
I seem to remember that there are some (but I forgot which).
