I'm not sure what you're looking for: an ACL (AutoCorrect List) is not a
*dictionary*, they're separate & distinct resources. Have a look at the
information on this page along with the pertinent links:
http://word.mvps.org/mac/SpellCheck.html
You'll most likely find your answers there. If not you'll be in a much
better position to express what the remaining problem might be
Also, make sure you have Office fully updated -- use Help> Check for Updates
to make sure you're at the 12.1.7 level & run Disk Utility - Repair Disk
Permissions from the Applications/Utilities folder.
