Where does "行かれん" come from and what are its characteristics?


Thanks to
[Weblio](https://www.weblio.jp/content/%E8%A1%8C%E3%81%8B%E3%82%8C%E3%82%93),
I know that it means 行ってはいけない but I don't understand well the story with
《標準語》(that is in the definition page), its level of politeness,etc




The page you liked is an entry of 鳥取弁辞書. 行かれん is a dialectal form, and the 標準語
section shows its equivalent in standard Japanese.

In many western dialects, `未然形 + (ら)れん` expresses prohibition ("don't") or
negative potential ("can't"):

>   * 読まれんよ。 （読むなよ／読めないよ。）
>   * 見られん！ （見るな／見えない！）
>   * 寝られん！ （寝るな／寝られない！）
>   * そんなん、せられん。 （そんなこと、するな／できない。）
>

Godan verbs take れん, ichidan verbs take られん, する becomes せられん, and くる becomes
こられん. Speakers of standard Japanese can easily understand the potential
meaning because it's very close to (ら)れる, but they are generally not familiar
with the meaning of "Don't".

There are [signboards that say
泳がれん](https://thegoatthatwrote.net/2011/07/30/warning-deadly-but-cute/) in
Tokushima prefecture. This means "Do not swim" rather than "You cannot swim".

Note that (ら)れん is not used in Osaka. Osaka people say 読まれへん ("can't read") or
読んだらあかん ("don't read").
