(Try this without ALIAS... ;-) JN> Either way, doesn't it still take up another word slot in the global JN> dict^H^H^H^Hcontext. If you use ALIAS, you are not using slots in the global context AFAIK. Also, you can translate the PARSE dialect or any other dialect using ALIAS; I don't know any other way to do it. JN> I must be missing something.

You should ask Carl. ;-) I can only make guesses about the current implementation, which a) would break if you could alias a word that has already been added to system/words, since it would mean having the same word twice in system/words (or in any other object that was created and used that word) and b) would break if you could unalias a word since then it would loose its bindings.
