This tip applies to Word 97, 2000, 2002, and 2003
Leonard has received a message that his custom dictionary is full. He wonders if he can expand it or find a way to use the CUSTOM2.DIC file that his copy of Word doesn't seem to recognize.
There's a good chance that the custom dictionary isn't really full; Word sometimes gives this message in error. Word MVP Suzanne Barnhill discusses this error a bit at her website and provides a link to the Microsoft Knowledge Base:

There is no real way to expand a dictionary if it really is full, but you can instruct Word to recognize and use other dictionaries on your system. Follow these steps:

Figure 1. The Spelling & Grammar tab of the Options dialog box.

Figure 2. The Custom Dictionaries dialog box.
Word will now use the dictionary you specified in step 7 as the dictionary for its spell checking tasks.

Thanks for the tip.
My standard dictionay (size is about 10Kb) is apparently full. So I followed your tip. However, once the new dictionary has been added and made the default one, Ms-Word keeps sending message "Dictionary is full" when I try to add a new word to it.
So : 1) apparently the tip does not seem to work, and 2) by the way is it really expanding the original standard dictionary or is it ignoring it when default is set to new user dictionary ?
Thanks for your help.
Best regards
N.B.: I realize that the word I wanted to add to dictionary contains an unsupported Pali character, and I think this is why this message "Dictionary is full" has popped up, although ist meaning does not fit the situation at all...

Got a version of Word that uses the menu interface (Word 97, Word 2000, Word 2002, or Word 2003)? This site is for you! If you use a later version of Word, visit our WordTips site focusing on the ribbon interface.
