I noticed that an old post of mine about adding dictionaries to WPS Office, has been receiving some attention recently. I quickly checked the links and it seems they are dead, also the file paths listed there no longer apply for WPS Office v11. Therefore, I decided to check how to add dictionaries to version 11.
I have been using WPS Office for quite some time now, and I am really not looking back. The default spellcheck that comes with the office is American English (en_US). I wanted to add a spell check in Writer for British English, since this is what I normally use for documents.
NOTE (03 April 2021): Please, check this newer post for updated howto for WPS Office 11.*!
