I added a lot of words to the standard Mac OS X system-wide dictionary on a given machine, and would like to transfer that specific list of words to another machine. Where / in what file(s) is that list of words stored?

My computer shows a variant of this -- I have ~/Library/Spelling/en. This suggests that OS X will save dictionaries by ISO code for each language. – Doug Harris Apr 30 '10 at 14:01
Seems to work for me. I copied everything under ~/Library/Spelling/. I had to logout/login again for the changes to be visible. – ebruchez Nov 6 '13 at 23:04

For those attempting to find the Unix standard words file, it's at /usr/share/dict/words.
