I wrote a small command to search the translation of a word with the wonderful site : wordreference
To use the command, open Ubiquity, and write one of the two command code : « wr » or « wordreference » then the word to translate and finally the language code. So for example :
wr dog enfrwordreference chien fren.
All the language in wordreference are supported. You just have to know the right code.
You can check the small video I made to see the command in action.
