I have added the imperfetto di cortesia to the imperfetto indicativo page.
I’ve now completed the page for the imperfetto including dozens of examples – it can be found here.
If you find any small mistakes, or indeed any howlers, please fammi sapere. And if you have any suggestions for improvements to this page or others, again please make contact.
Postscript: I have now made some changes to the imperfetto page as a result of some suggestions. These include the use of the heading ARCHETYPAL REGULAR VERBS instead of MODEL REGULAR VERBS. Archetypal is a little more wordy a word than model but, as it was pointed out, it would be easy to confuse model with modal – and we wouldn’t want that!
