One problem is that the English page is about the *word*, not the *thing*. It should not be a subclass of neighborhood, but rather an instance of word (or the description should be changed). Similarly, if the item is about the word, then actual neighborhoods can't be an instance of that word.
Another problem is that a loan word is often generic in the original language (e.g. in German, "angst" just means fear, there is no German translation for the English "angst", even though it's taken from German).
By the way, the corresponding German word is, I suppose, "Kiez" - which has Articles in German, English (about the word or the thing?), and several other languages. Whether a German "Kiez" is the "same" as a Brazilian "Bairro" is up to you to decide...
These are problems of semantic modeling, and drawing lines between similar but culturally different concepts. They are tricky issues, but I do not think the software can help with this.
At some point, we may add proper modeling for linguistic entities, to cover the needs of Wiktionary. Then you could model all the relationships of the words, but you'd still have the same issue with the items.

Bairro (Q16837104) has the English description: "a Portuguese word that refers to a community or region within a city or municipality". It is a subclass of neighbourhood (Q123705).
There are many neighbourhoods in Brazil with the 'instance of' property set to bairro (Q16837104), for example: Gamboa (Q3757943), Riachuelo (Q3934201) and Noal (Q10337174).
Q16837104 includes sitelinks to enwiki and trwiki, but not to ptwiki. There is a Bairro article on Portuguese Wikipedia, represented by the Wikidata item neighbourhood (Q123705).
It would be useful if bairro (Q16837104) could include a sitelink to the bairro article in Portuguese Wikipedia, but this is forbidden because it is already linked to from another item.
In English Wikipedia we have articles describing two concepts, neighbourhood and bairro, but in Portuguese Wikipedia there is only a single article for the concept of neighbourhood.
There is another item, barrio (Q1761572), for the Spanish variant of this word.
It would be useful if we could add a way to represent loan words in Wikidata. Then we can add a statement that says Bairro (Q16837104) is a loan word of neighbourhood (Q123705) in Portuguese.
