Thank you very much!
The issue is that I had already visited the Crusca web page, but it's not an actual 'corpora', as the Spanish one that I've already mentioned or the COCA, of the American English.
Is there a real CORPORA where you can look words up in their contexts?
If you know it, please, write me back!!
Thank you very much again!
Unfortunately I do not know how to help you.
I'm very sorry. If you need, feel free to contact me through skype. I think that two minds are better than one!
Have a nice day!
