Yes, "definition space" is the basic idea -- what's sometimes called
"name space" with other languages. The technical term in Mathematica is
"context".
Look up "context" in the Mathematica Documentation Center. And in
particular see the page "tutorial/Contexts".
Also the page "tutorial/ContextsAndPackages".
