Feeds automatically uses English Plurals for all languages.

I noticed this too in the Dutch language. It always puts an 's' after the name of a content type, where using 'en' would make more sense in Dutch.

For example, I sometimes see this message:

4 Onderdeels bijgewerkt.

(meaning: updated 4 components)

While the correct Dutch phrase in this case would be:

4 onderdelen bijgewerkt.

I didn't see a way yet how to fix that. Content types don't have plural labels, just one label.

You say it happens for entity type names as well?

It would be cool if we could fix this issue in a way that it still looks nice in English, for example "Created 6 articles" instead of "Created 6 Article".

Because in Drupal 9, Drupal core no longer has a dependency on doctrine/inflector. So if we keep using the inflector, then Feeds will be harder to install for non-composer users in Drupal 9. See also #3129114: Fix Drupal 9 test failures.

I see the following interesting piece in the patch from #2765065-101: Allow plurals on bundle labels:

+      if ($label = $this->label()) {
+        $this->label_singular = mb_strtolower($label);
+      }
+    }
+    return $this->label_singular;
+  }

+    if (empty($this->label_plural)) {
+      if ($label = $this->label()) {
+        $arguments = ['@label' => mb_strtolower($label)];
+        $options = ['langcode' => $this->language()->getId()];
+        $this->label_plural = new TranslatableMarkup('@label items', $arguments, $options);
+      }
+    }
+    return $this->label_plural;
+  }

For the content type 'Article' without specific singular and plural labels this would result into:

• "Created 1 article" in the singular form.
• "Created 6 article items" in the plural form.

This seems like a nice workaround. I see that in #2765065: Allow plurals on bundle labels, the label is also converted to lowercase. However, that would at least be incorrect for the German language (as also noted on that issue). But even in other languages you can't be sure whether it's correct to convert the label to lowercase. For example, on one site I have a content type called 'FAQ' - an abbreviation - and in that case I think it's better to keep it capitalized. In that case the messages in Feeds would become:

• "Created 1 Article" in the singular form.
• "Created 6 Article items" in the plural form.

The patch makes the plural bundle label "@label items" and hopefully updates all related tests.

I ran the tests against D9 to check if there are no more mentions of Doctrine\Common\Inflector\Inflector in the code base. And this appears the case!

What do you think of the patch in #7?

Thanks for taking a look, @mikran

Committed #7.
