"Elefanterna äter äpplena."

Translation: The elephants eat the apples.

[OhBogy]

Ett äpple, äpplet, äpplena, why its äpplena and not äppleta?

[HelenCarlsson]

You missed one word:
ett äpple - äpplet
flera äpplen - äpplena

[OhBogy]

Oh that way, tack!

[Yerrick]

Is this the standard indefinite/definite pluralization for ett-words ending in a vowel?

[HelenCarlsson]

Yes.

[Vinny.Is.Here]

Difference between "applet" and "applena"?

[Zmrzlina]

Äpplet = The apple

Äpplena = The apples

[Vinny.Is.Here]

Thank you.
