Sie zählt die Orangen
She counts the Oranges
They count the Oranges
I am confused.
sie can mean : you (formal adressing)
she or they
if Sie is written with capital S it is usually you (formal adressing).
exception: in beginning of the sentence. since a sentence in german always starts with a capital letter.
in that case: look at the verb form and the context .
since both 2.person sing (only the formal form) and 3. person plural are using the same verb form you would need the context to distinguish if it is you count... or they count...
in your exemple however the verb is written in 3.person sing. so it must be: she counts the oranges.
The way I remember it is by looking at the verb. If it has the "en" ending that reminds me that it is talking about the plural form and that means "they": zählen, mögen, lesen. As far as I have learned that's always the case. If the verb doesn't end in "en" then I know that the "Sie" means "she". My apologies if this is too simplistic. I had problems with this too until I noticed this pattern.
1 Person Singular (I) = I sing - Ich singe 2 Person Singular (you, informal)= You sing - Du singst 3. Person Singular (she) = she sings - sie singt !! femininum
1 Person Plural (we) = we sing -Wir singen 2 Person Plural (you) = you sing - Ihr singt 3 Person Plural (they) = they sing - sie singen
2 Person Singular (you, formal) = you sing - Sie singen
The formal 2nd Sg is always same build like 3rd Person Plural.
