What you're looking for is "wordlists" or "vocabularies". They do 
provide a capability for specialized namespaces. There is a tendency for 
newbies to over-use them, though. My advice is to use them sparingly, 
for specialized code that supports a few high-level public words that 
use it. I always recommend studying the implementation of a 
well-regarded Forth system (ideally more than one) to see how 
experienced Forthers use these facilities.

Cheers,
Elizabeth
