I have used the WordWeb free dictionary as my primary dictionary for many years, on both Windows and Android. When I use Linux, I immediately miss having a Linux version of WordWeb.
Thankfully, it seems to run fine under Wine as described below:
$ sudo apt install wine
Download the Windows installer of WordWeb from here.
Run the WordWeb installer using Wine:
$ wine wordweb10.exe
Tried with: WordWeb 10.33, Wine 6.0.3 and Ubuntu 22.04
