This seems like a very basic issue but I could not find any infos about it. I assume the main dictionary is stored as a language-specific file at some location. I would like to remove unneeded terms; I don't know about other languages but the German dictionary contains some very outdated words as well as verbosity unrelated to our industry sector.
I have checked the folder \users\username\AppData\Roaming\Adobe\Linguistics but this is empty.
