The verb would be conjugated differently.
I suspect you know about capitalization of "sie/Sie" already, but I'll include it in case other readers aren't aware.
Sie essen - you (formal) eat -----> Sie is always capitalized
Sie essen - they eat -----> Sie is only capitalized at the start of a sentence
Sie isst - she eats -----> Sie is only capitalized at the start of a sentence
Hope that helps!
Ok, but still Er/sie/es verbs ends with -t so why does it end with - en here? its almost as its formal Sie, i can't understand this.
Because this particular form of "sie" is referring to more than one person, so it is plural. sie (small s) means SHE, Sie with a capital S means YOU in formal German direct conversation, and sie with a small s, again, can also mean THEY - plural. You know if it is the plural form because verb ends with 'en' - like in this case :)
You can't start a sentence with 'You'? - seems I just did.. now im confused, as if you did how would you know if was formal or not
I don't know what you mean by "You can't start a sentence with You", and I think we might both be misunderstanding each other. So I'll try again...
sie (small letter "s") = they or she
Sie (capital letter "s") = you (formal, singular or plural)
sie isst Tomaten = she eats tomatoes
sie essen Tomaten = they eat tomatoes
Sie essen Tomaten = you eat (formal, singular or plural) tomatoes
At the start of a sentence you need a capital letter, so if the sentence starts with "Sie" you would not be able to tell if "Sie" was you/they/she by the letter "s" alone. So, you look at the verb conjugation.
Sie isst Tomaten. = She eats tomatoes.
Sie essen Tomaten. = They eat tomatoes or You eat tomatoes.
For "Sie essen" at the start of a sentence you need context to tell if it is you (formal) or they. Almost all of the Duo sentences that start with "Sie" and have a verb conjugated ending in -en (like "Sie essen") accept both "You eat" and "They eat" because there is no way to tell without context. Does this help?
"You (formal plural) are eating tomatoes" is also correct. It didn't accept my answer, however, and I can't "report" it because there are only three options listed to report (unlike some of the other languages I've studied at Duo). You can report (1) that the audio is bad, (2) the German is unnatural or incorrect, or (3) the "correct solution" is unnatural or incorrect. The correct solution Duo uses (they) is fine, it just happens to be one of two possible ways to translate "Sie essen Tomaten." When the pronoun is at the beginning of the sentence, it erases the capitalization distinction between "sie essen" and "Sie essen." Without more information to provide context, both translations should be counted as correct.
Could this not be the formal version of "You eat tomatoes", as well as plural? I would normally put "They eat tomatoes" but I went for formal "you" for a change and to see if it would accept it but it marked it wrong?
You can look at the verb ending, which will almost always be -t when sie means "she" and -en when sie means "they".
For example, sie isst = she eats, sie essen = they eat. sie trinkt = she drinks, sie trinken = the drink.
The forms for "to be" are irregular: sie ist = she is, sie sind = they are.
I got this wrong as I entered the answer, "correctly" but in English. But for this I am happy as to me it seems I might finally be getting it!
How can you tell when to say "she" and when to say "they"? Is one capitalized and the other left lower case??
I don't understand why "sie" cannot be used as "she" because if it is a capital, you can't tell.
but you can tell by the following word, if it was 'she is eating' then it would say sie 'isst'. But because it says is 'essen' you know that it isn't talking about a single female.
