enrich dictionary in ms word

hello

can anyone tell me how can I enrich default ms office dictionary?

I have my own custom greek dictionary

I want to compare it with msoffice’s dictionary

then, I will add the words that arent already included into msoffice’s dictionary

ofcourse I want to add them in batch, not manually

any ideas?

thank you!

PS: I tried to use my custom dictionary, but its 7MB and makes msoffice freeze when it tries to spell check with it
this dictionary can be used flawlessly with a notepad replacement program, pspad
does this make sense? am I doing something wrong? how can a small program run a 7Mb dictionary and msoffice cannot?
