"He is eating one orange."

Translation: Er isst eine Orange.

[Gallifrey_]

In which situations do you use "eins" instead of "ein/eine/einen"?

[csnyder5]

I would like to know too. I was afraid eine would be wrong because it specified one.

[jfinley6]

Can this also be "He is eating an orange"?

[wataya]

yes

[ben420]

how can you tell which one it is though??

[perry_goh]

eine can be used as "an, a or one" the only difference will be the gender. do correct me if i'm wrong ^^

[Francis-Ol]

Eating one orange means one and not two... An orange is different... Why is eins wrong?

[geetharavi]

Is "Er isst einen Orange" wrong?

[bigdaddybigboy]

When the noun is feminine ein becomes 'eine'

[wataya]

Yes. "Orange" is feminine.

Why is it 'er' as opposed to 'er?' thanks :)
