To round off the week in the same way we began, here is a resource which I like very much.
According to the introduction by the webmaster, “Il Vocabolario Etimologico della Lingua Italiana di Ottorino Pianigiani” was first published in 1907 in two volumes by Albrighi & Segati, and followed in 1926 by a volume of Aggiunte, corrections and variations (Ariani, Florence). It was then republished on several occasions by different publishers.
The people that have created this online version have called it a ‘work in progress’. It doesn’t seem to have been updated for some time, but I think it’s just fine as it is.
Discover the dictionary here. I’ve found it invaluable for looking up rarely used Italian words.
The only thing that bothers me is the advertising on the site, but I do understand that funding is required in some way!
