This proposal has been rejected. This decision was taken by the language committee in accordance with the Language proposal policy based on the discussion on this page.
A committee member provided the following comment:
The community needs to develop an active test project; it must remain active until approval (automated statistics, recent changes). It is generally considered active if the analysis lists at least three active, not-grayed-out editors listed in the sections for the previous few months.
Language name in your language. This will appear in the language list on Special:Preferences, in the interwiki sidebar on other wikis, ...
Language Wikidata item
Item about the language at Wikidata. It would normally include the Wikimedia language code, name of the language, etc. Please complete at Wikidata if needed.
"Wikipedia talk" (the discussion namespace of the project namespace)
Enable uploads
no
Default is "no". Preferably, files should be uploaded to Commons.
If you want, you can enable local file uploading, either by any user ("yes") or by administrators only ("admin"). Notes: (1) This setting can be changed afterwards. The setting can only be "yes" or "admin" at approval if the test creates an Exemption Doctrine Policy (EDP) first. (2) Files on Commons can be used on all Wikis. (3) Uploading fair-use images is not allowed on Commons (more info). (4) Localisation to your language may be insufficient on Commons.
"Continent/City", e.g. "Europe/Brussels" or "America/Mexico City" (see list of valid timezones)
Additional namespaces
For example, a Wikisource would need "Page", "Page talk", "Index", "Index talk", "Author", "Author talk".
Additional settings
Anything else that should be set
submit Phabricator task. It will include everything automatically, except additional namespaces/settings. After creating the task, add a link to the comment.
El chjanino è la lengua uffičjale de la Chjana, el parlen tutti da Arezzo n giue, e nn è manco punto sempliče, te l dirò eh! Ma è na roba čitti, na roba, mondjale, spečjale.
The Chianin is the official language of (Val di) Chiana, everybody speaks it there, all the way from Arezzo; it is not easy at all, to be honest, but it is so great and enjoyable!

This seems to be w:en:Tuscan dialect or a subdialect of that, which is apparently considered by SIL to be Italian. Thus there is a Wikipedia covering this, it.wikipedia.org. --Prosfilaes (talk) 09:06, 28 April 2020 (UTC)Reply[reply]
It surely is a Tuscan dialect, but it is quite different from standard Italian in various features, and if Neapolitan or Venetian dialects have a Wikipedia on their own I can’t see why Chianino wouldn’t deserve it as well.
It is generally left up to w:ISO 639 to decide whether or not a dialect is a separate language. They have said that Neapolitan and Venetian are separate languages, and Tuscan is part of Italian. It is possible to submit a request for a new language tag to them; any chance of getting a Wikipedia for a language without an ISO 639-3 tag will come if and when they reject it.--Prosfilaes (talk) 09:19, 29 April 2020 (UTC)Reply[reply]
@Prosfilaes: Sorry, but per [1], due to the COVID-19 problems, submissions of new ISO code requests are suspended until future notice. --Liuxinyu970226 (talk) 07:09, 30 April 2020 (UTC)Reply[reply]
That's not what that says, but if it takes more time to get a response from SIL, it will take more time to get a response from SIL.--Prosfilaes (talk) 09:02, 30 April 2020 (UTC)Reply[reply]
I do not want to seem rude, but I am inclined to suppose that this page is actually a hoax. Italy has a lot of very different dialects and languages, but this particular variable of Tuscan is definitely far from being officially recognized or studied by linguists. - εΔω 22:33, 29 May 2021 (UTC)
@Sotiale: So, this is just a hoax request, as it looks hoax, smiles hoax, and even quacks hoax, shouldn't this be speedy rejected? --Liuxinyu970226 (talk) 23:25, 30 May 2021 (UTC)Reply[reply]
