Why is the plural of mann "Männer"?
Because of umlaut -- specifically, Germanic umlaut or i-affection ( https://en.wikipedia.org/wiki/Germanic_umlaut ):
a type of linguistic umlaut in which a back vowel changes to the associated front vowel (fronting) or a front vowel becomes closer to /i/ (raising) when the following syllable contains /i/, /iː/, or /j/.
The old plural of mann was manniz.
The -i- in the second syllable of the plural raised the vowel of the first syllable -- and even after the -i- later turned into a neutral vowel (written "e"), the changed first vowel remained, and so we now have Männer with umlaut. (The change of final -z to -r is also regular: see https://en.wikipedia.org/wiki/Rhotacism_(sound_change)#Germanic_languages .)
English has traces of this umlaut in word pairs such as "foot : feet" or "man : men" (compare German Fuß : Füße and Mann : Männer).
So basically: for historical reasons involving how the words sounded like 1000 years ago.
It keeps telling me that I am wrong when it's what I typed
Check carefully whether you wrote "man" or "men", and "woman" or "women" -- does the word end in AN or in EN?
If you are completely sure that what you typed matches the answer given, letter by letter, then a screenshot would be helpful -- please upload it to a website and paste the URL here.
I wrote […] "you are man and we are women"
Männer is plural -- you should have written "men" with EN and not "man" with AN.
I give you a lingot for quoting your response rather than just saying "I wrote the correct answer but it was marked wrong", which doesn't help anyone.
The answer changes every time, first its pluar, then its singular.
There are several different but similar sentences.
Pay attention to the sentence and translate accordingly.
Sometimes the men are first, sometimes the women.
Sometimes "we are" is first, sometimes "you are".
Don't get into a rut of assuming that all similar sentences are identical -- read each sentence carefully and translate accordingly.
If it says "you are" (and it's obviously talking to several people), translate that part with ihr seid.
If it says "we are", translate that part with wir sind.
And pay attention to the order in the English sentence when translating into German.
Why sometimes Sind is used with Männer and sometimes Seid?
Because the verb depends on the subject (i.e. whether it's wir or ihr or sie) -- not on whether there is Männer or Frauen or Kinder or anything else on the right side of the verb.
Like how in English we say "I am a boy" and "He is a boy" -- the verb choice (am, is) depends on the "I" or "he", not on the "a boy".
WHAT WAS WRONG WITH MY ANSWER???
Nobody can see your answer, so nobody can answer your question.
What was your answer? What was the entire sentence that you typed?
Even better: if you have a screenshot, please upload it somewhere and paste a link to the image here.
If I had to guess, though, you might have written "man" rather than "men" and/or "woman" rather than "women".
Typos that result in a valid word are considered full errors, because the system has no way of knowing whether you wrote (say) "woman" because your finger slipped from the E key to the A key and you really meant to type "women", or because you fully intended to write "woman" because you misremembered what Frauen means in German.
What is wrong with my answer?
Since nobody can see what you wrote, please always quote your entire answer when you have a question about it.
Even better, take a screenshot, upload it to a website somewhere, and post the URL to the image in your comment. Then we can see what you actually wrote, rather than what you intended to write.
can i say? du bist manner und wir bist frauen
- du bist is used when speaking to one person. One person cannot be "men". So the person saying "you are men" has to be speaking to multiple people -- you need the plural form, ihr seid.
- There is no German word manner. "men" in German is Männer, with a capital M followed by an ä (or ae if you can't write that letter: Maenner).
- wir bist makes absolutely no sense. Like saying "we am": the subject and verb simply don't fit together. bist is only for du. wir requires the verb form sind -- wir sind = we are.
- frauen does not exist in German, either. The correct spelling is Frauen.
While Duo unfortunately does not care about capitalisation, you should learn it if you want to write German correctly. All nouns are capitalised.
why is my answer not accepted?
I don't know. What was your answer?
Since nobody can see what you wrote, please always quote your entire answer when you have a question.
Even better, take a screenshot of your answer (and any possible error messages or corrections), upload it to a website somewhere (e.g. imgur), and put the URL to the image into your comment.
I see a report from around the time of your comment, asking for "You are men and we are woman" to be accepted.
But Frauen is plural (= women), not singular (= woman).
Am not sure if my ears are tuned yet to German sounds, but is there a faint g sound at the start of the sentence at normal speed? Also is the second syllable of Männer not pronounced or swallowed by the oncoming und ? - it sounds more like "men" to me. Thanks for any help with this.
Use du when you are speaking to one person.
Use ihr when you are speaking to several people.
Since you are saying that "you are men", you must be talking to several people -- because one person cannot be "men" (plural). So you need ihr in the German sentence here.
Using du to speak to several people would be like using "he" to talk about several people in English.
Is there a difference in attitude here. Is the' Ihr seid' somewhat belittling compared with the' wir sind?' If I were to say' 'wir sind Maenner und ihr seid Frauen' would this show that the men had a somewhat arrogant attitude towards the women? I am interested in the nuances here
Is the' Ihr seid' somewhat belittling compared with the' wir sind?'
ihr seid = you are
wir sind = we are
That's all there is to it. Nothing about being better or stronger or more arrogant. Just about whether you're talking about your listeners or about a group that includes you.
Would you say "I see he and he see I" in English?
No; it has to be "I see him and he sees me".
Would you say "We are reading a book." when you are talking about what you yourself (one person) are doing? Or would you say "I am reading a book."?
English distinguishes between singular and plural in "I - we".
It distinguishes between subject and object form in "he - him" and "I - me".
German du - dich - ihr - euch is just more of the same: singular du, dich versus plural ihr, euch; subject du, ihr versus object dich, euch.
The fact that English doesn't distinguish singular from plural in "you", nor subject from object, is English's problem.
Once English "gets its act together" and gets rid of singular and plural everywhere, as well as subject and object forms, and that funny -s for verbs in the "he, she, it" form, then we can start talking about what German "should" do.
