I was wondering something...

I was thinking of this just now. In Ayhan, the bases of words are
roots. Roots are generally nouns,  or adjectives/adverbs, but
sometimes the roots cannot be used alone (such as for abstract
concepts, like "thought") and need a prefix to make it into a noun,
adverb/adjective/ or a verb (so these roots remain "unfunctional"
until they are augmented with an affix to determine its role).

I know there have to be other natural languages which do that, so i'm
not asking if this is an ANADEWism (although if you'd like to chime in
on that angle you can), but, what I want to know is, are there other
conlangs that do something similar?

Or maybe I have simple stems and don't realize it, which then makes it
all very mundane :).
