I want to develop Microsoft Office language packs and proofing tools for a new language.

Hi @bb.kang

You can create a .dic file, and then add this file, and create a Custom Dictionary in Microsoft Word.

The answer I want is not a custom dictionary.

I have defined my own dictionary of legal terms.

I want the dictionary I created to be displayed in the form of a dictionary in the Research window of MS Word.

In other words, I want to add the dictionary I created to the related books in the Research option.

The currently installed dictionary is stored in the MSGR8EN.lex file format at C:\Program Files\Microsoft Office\Office16\PROOF.

Can I change my dictionary into a dictionary file (lex file) and add it to the related books in the Research option?

Please answer.
