Ihr and Du
What it is difference between "Ihr" and "Du"? For example: 1. Du hast eine apfel. 2. Ihr habt eine apfle.
du is for when you are speaking to one person (to whom you would not say Sie)
Ihr is when you are speaking to more than one person. (So they are sharing an apple)
note: you can use Sie to more than one person.
EDIT: having just read 7hAu0bvY's comment, I now see that you got the gender wrong on Apfel... I'm cross with myself for missing that, because apple is one of the first genders I ever fixed in my head... I think of William Tell...A MAN with his SON tied to a TREE... there is an APPLE on the boy's HEAD... the story also has an ARROW and a BOW.
APPLE der Apfel
TREE der Baum
BOY der Junge
HEAD der Kopf
MAN der Mann
ARROW der Pfeil
BOW der Bogen
Now, you will have noticed that it should have been a crossbow...but sadly crossbow is die Armbrust
For the purists out there, crossbows didn't fire arrows, they fired quarrels... which is nice because a German word for quarrel is der Streit. (now i've no idea whether Germans called a crossbow bolt a Streit (i doubt it) but it doesn't matter because this is all just a method i use for remembering genders)
Of course, you can give William a HAT (der Hut), and because it's a Swiss story, there has to be a mountain (der Berg) in the background ( der Hintergrund)... the only limit is your imagination :)
