According to documentation
https://docs.djangoproject.com/en/4.2/topics/i18n/translation/#how-django-
discovers-translations
Django will look for translations in the following order:

* LOCALE_PATHS directories
* 3rd party apps
* django/conf/locale

''I created example project with reproducing the issue at GitHub -
https://github.com/DmytroLitvinov/django-i18n-issue''

As for Python3.10 it works according to documentation, but if we start to
use Python3.11 and higher (like Python3.12) - we will see that the order
is not correct and it will take first from 3rd party app (like in my
example from django-allauth library).

To confirm that translation in LOCALE_PATHS are working correctly, we can
comment out 'allauth' in INSTALLED_APPS settings and see that translation
of word 'Continue' will be correctly taken from LOCALE_PATHS folders.

Comment:

Thank you for the report and the test project! Replicated and confirmed
this works on using Python 3.10
This appears to be a different issue to #34221 👍

Comment (by Vasyl Dizhak):

We've been working on this issue during the Sprints after the DjangoCon
Europe 2024 and this issue is related to #34221 as we can link it with the
same wrong behavior when comparing the plural functions.
Django uses the following plural function
{{{
"Plural-Forms: nplurals=2; plural=(n != 1);\n"
}}}
which matches exactly with the one from the demo repository
https://github.com/DmytroLitvinov/django-i18n-
issue/blob/main/locale/de/LC_MESSAGES/django.po#L19C28-L19C43, therefore,
local translations will be merged into the first catalog together with
Django's translations.

The `allauth` package has a different plural function that would insert
it in the first position in the translation catalog
https://github.com/pennersr/django-
allauth/blob/main/allauth/locale/de/LC_MESSAGES/django.po#L20

{{{
"Plural-Forms: nplurals=2; plural=n != 1;\n"
}}}

`gettext` would check first the 3d-party `allauth` translations catalog as
it has higher precedence, and only then look at the merged one containing
the local files.
We propose to close it as a duplicate to the #34221.
