The ๐ด plural is rare in German, and where it turns up tells you a word's history. ๐ฉ๐ช
Most German plurals change the word. Umlauts, endings, both. The ๐ด just sits there, the way English does it.
That is the clue.
๐ฅ๐ข๐ด ๐๐ถ๐ต๐ฐ โ ๐๐ถ๐ต๐ฐ๐ด
๐ฅ๐ข๐ด ๐๐ฐ๐ต๐ฆ๐ญ โ ๐๐ฐ๐ต๐ฆ๐ญ๐ด
๐ฅ๐ข๐ด ๐๐ฐ๐ง๐ข โ ๐๐ฐ๐ง๐ข๐ด
๐ฅ๐ฆ๐ณ ๐๐ฉ๐ฆ๐ง โ ๐๐ฉ๐ฆ๐ง๐ด
๐ฅ๐ข๐ด ๐๐ข๐ฃ๐บ โ ๐๐ข๐ฃ๐บ๐ด
Almost every one is a word German did not build itself.
It also catches anything German has no pattern for. Abbreviations, surnames, words ending in an awkward vowel.
So the ๐ด plural is German's shrug. No native pattern fits, so it borrows the foreign ending.
Which means you can often tell whether a noun was imported just by making it plural.
