No, it's really important to understand it in the first lessons, or you won't understand it later.
Formal you is very important in German, and it's the things you learn when you just start to learn a language, the very basics: the pronouns!
Just remember than the polite you (singular or plural, it's the same one), always uses a capitalization for the «S»: Sie. And is conjugated as a plural.
It's like saying «they are» to address only one person or a group of person to be polite. It's not so difficult.
@Zachary Yes, it's like Usted/Ustedes in Spanish.
So once again
I am - ich bin.
You are - du bist.
She/he/it is - sie /er/es ist.
We are- wir sind.
YOU ARE- ihr seid.
They are- sie sind.
Plus the formal way (f.e. to the elderly,tachers or in a formal letter) , where you ALWAYS mention the person with a capital letter. But you only use it in a very formal conversation!!! or when you want to be very very very polite!
You are - Sie sind You are (pl) - Sie sind
Frauen is the correct spelling.
Duolingo lets you use ue in place of ü -- and thinks that works the other way around as well, i.e. that it's permissible to turn Frauen into Fraün (which is nonsense).
And sometimes, Duolingo lets you omit the dots (which is also bad), so it will allow Fraun for Fraün as well.
But both Fraun and Fraün are simply nonsense in German, regardless of what Duolingo allows through.
can someone tell me why it tought me she was sie
Because "she" in German is sie.
And "they" in German is also sie.
They used to look different a couple of thousand years ago, but because of sound changes, they ended up looking and sounding the same.
So now you have to look at the verb to know whether to translate sie as "she" or "they".
Lowercase sie can mean
Uppercase Sie is the formal "you".
At the beginning of a sentence, you can't tell the difference, since the first word of a sentence is always capitalised in German.
(And if you think it's silly that one word can have four different uses: English does the same with "you". Singular subject: "Anna, you are a girl." Singular object: "Anna, I see you." Plural subject: "Julia and Anna, you are girls." Plural object: "Julia and Anna, I see you.")
Why its she-sie,and they-sie?
Just the way it is.
They used to be distinct a thousand years ago or so (siu versus sia), but have since fallen together into sie -- presumably as part of the general neutralising of word-final vowels. (Look at the many German words ending in -e.)
