Sorry but nonsense There is only one source who says Nocciolini all the other institutional sources say Nocciolini di Canzo or Nocciolini Canzo Noccioli  Canzo or similar look also  in addiction to the already said  Official touristic site of Comunit Montana And also the only source who says Nocciolini without Canzo has an OFFICIAL correspondant in the decree of Region Lombardy who says Nocciolini  Canzo Thats not an interpretation but only the comparison between two official documents The Google search experiment goes as you say precisely because nocciolini is a term used for many things Please look at the first result of the search Nocciolini cookie You can see the picture they are a cookie but totally different from the cookies we are talking about If you obtain only  with Nocciolini cookiebiscuit Canzo you dont surprise me because Nocciolini di Canzo are unknown out of western Lombardy All the other results you had excluding the word Canzo refer to other topics and thats a confirmation that the complete nomination Nocciolini di Canzo is absolutely necessary Wikipedia Article title policy says to observe the criteria of recognizability naturalness precision conciseness consistency The omission of di Canzo is against recognizability as I said but I see that you didnt pay attention to it there are also Nocciolini di Chivasso in Italy in the region of Piedmont another cookie naturalness all in western Lombardy say Nocciolini di Canzo and when they say Nocciolini its only because we are already talking about the town of Canzo precision you arent precise if you use a vague term of Italian language whose meaning is little hazelnuts to define ONE of the at least three pastries I saw on Google made with hazelnuts we native consumers and caller of the Nocciolini di Canzo perceive the matter in this way Nocciolini is a common noun but with the precisation di Canzo it refer to a specific product different case with Panettone because on Italian dictionaries Panettone means one thing the one of Milan thats not a common noun Evidently you cant use the criterium of conciseness in this case because first of all comprehensibility is required  Regarding your accusation of insult I didnt have intention to make insults I was only laughing because the effect of the action you propose would be very funny for an Italian speaker And I was explaining  as I see also FoCuSandLeArN recognized  that it would be a big error from the point of view of recognizability and precision I synthetize that the title of this article must precise not only that we are talking about a cookie but also that we are talking about this cookie
