plural form of nouns

[AirbusA321]

Does the plural form of nouns derived from other languages always end with -s?
For example:
zeitgeists
mustards
ubermenschs
tonneaus
kirschwassers
poltergeists
volkswagens
symbolisms
raumdeuters
gemutlichkeits
stratospheres
cadeaus

Does the plural form of nouns derived from other languages always end with -s?
For example:
zeitgeists :cross: This is uncountable
mustards :tick: (though it's usually used uncountably)
ubermenschs :cross: When it's used, it's "ubermenschen".
tonneaus
kirschwassers
poltergeists :tick:
Volkswagens :tick:
symbolisms :cross: This is uncountable.
raumdeuters
gemutlichkeits
stratospheres :tick:
cadeaus

I have marked several in red because I have never heard them used in English so there is no answer to your question. I have marked the others as correct or incorrect and given some comments.

That's an odd mix of words. Too diverse a mix to give you a rule, I'd say. What do you mean exactly by "derived from other languages"? Some of those words are English words, some are loanwords, and some are just foreign words.

 

[AirbusA321]

All these words are French or German, at least in the singular form, and they appear in the wikipedia list of English words derived from other languages

"mustard", "symbolism", and "stratosphere" are English words.

The majority of words on the list are German.

The three words you list are not really 'derived' from other languages if by 'derived', you mean 'based on' or 'adapted from'. These words have been borrowed directly from French and German, and they exist in the same form. In linguistics, they are known as loanwords. In pluralisation, they may follow the rules of the language they are borrowed from (if there is a reason the '-s' rule does not work), but otherwise they follow normal English patterns.

The word mustard could be said to have derived from Old French, but is considered as a regular English word, not a loanword.
The word stratosphere is an English word consisting of Greek roots. It is not a Greek word nor a loanword.

"mustard", "symbolism", and "stratosphere" are English words.

Yes but they are French words in the first place. They were exported to England maybe 1000 years or so ago.
"la moutarde", "le symbolisme", "la stratosphère"

"la moutarde", "le symbolisme", "la stratosphère"

"Mustard" is an old word, but "symbolism" and "stratosphere" have nineteenth- and twentieth-century roots. All three are English words.

No, that's not true.

"la moutarde", "le symbolisme", "la stratosphère"

These are French words.

The reason why mustard and moutarde look similar, (but not identical) is because they share their etymologies. They both derive from Old French. A significant proportion of modern English words come from Old French, and a much higher proportion still of modern French words.
