Hi Grasshopper,
searching for *.lex results in 29 files, here and now.
The largest is nls302en.lex,
with indeed a lot of words in it,
and which wasn't there in ealier version of Office.
Which versions? I don't know.
It does in no way mean that Jay is wrong.
Files like MSSP3EN.LEX contain some words,
word parts and a rules which produce possible words, like
Bananamother
Bananacheapmother
Bananacheapearlymother
I a very simplyfied way.
I don't dare to recommend a way to extract
the Words from nls302en.lex.
It's not that simple and probably illegal, too.
How MSSP3EN.LEX and nls302en.lex interact, is a secret.
Spelling check knows "Kissinger",
yet it can't be found in MSSP3EN.LEX,
but in nls302en.lex.
There must sources on the web available for free.
Sorry.
