Need better dictionary (US-America). Too many words simply not there. How to replace?

There are a number of words that aren't in the dictionary, including common acronyms, and adding them becomes a royal pain after awhile.

I'm not going to get into examples; there ought to be many here who have seen this before.

--->I'm willing to get down and dirty and add words programmatically from a known dictionary word list, but I don't know either the format or where it's installed<---

But there really seems to be no where online that I can find where someone else has done all this already.

And all the addons that I can find are about changing dictionaries by locale, or getting dictionary definitions.

Any ideas?

Thanks!

hi, you can put custom words into the persdict.dat file in your profile folder (one per line).

Perfect! Thanks.

All I need to do is write a crafty program (likely Java) to siphon through the very large word lists out there, check against the existing US-en dic file, and enter it if it doesn't exist.

I wonder if things will slow down some? LOL...
