Ein, Eine, Der, Die, Das

Get this.

...and before I start I'll mention the number of people speaking German around the world is decreasing. Gee, wonder why.

Every noun is a girl or a boy or nothing.

Der - male
Die - female
Das - neutral

I get this... It's the same in Spanish.

However, unlike Spanish you can't assume a words gender based on how it sounds. In Spanish, el gato, el platano: have "o" at the end so they are boys. la casa has an "a" at the end, it's a girl. This usually works and you can get by.

In GERMAN there is no reasoning to it.
der stuhl - the seat - boy
der kuli - the pen - boy
die lampe - the lamp - girl
die uhr - the clock - girl
das telefon - the telephone - neutral

The gender of a word determines words in the entire sentence, not just adjectives!!
Andrea says, "Das ist meine tasse."
Scotty says, "Das ist mein tasse."

I thought easy enough, I'll just learn the girl words since I'm a girl.

But I say, "Das ist dein tasse Scotty, und das ist deine tasse Andrea."

BUT, if the cup, which is a girl.... was a boy like a chair.

Wait, ???? I don't know. I thought I was doing good. Oh, I'm confused I have no idea anymore...

An hour and a half of German lessons twice a week and I'm more confused than when I started...
