The ‘Dacco‘ project (Diccionari Anglès-Català de Codi Obert) started the creation of a dictionary some years ago. The philosophy of this project is that everyone can participate and contribute with words and translations, similar to the way ‘wikipedia’ works.

It is not perfect, but it is getting better and better with time. If you want to look up a word, simply use the search function (‘ctrl + f’ or ‘ctrl + b’) and type the word you want.
