"Han spiser kylling."

Translation: He eats chicken.

-en makes it definite, no? I didnt realize that it determined gender.

[Robbadob]

Definite word can end in either -en (common gender) or -et (neuter gender).

kage (c) / kagen
kylling (c) / kyllingen
æble (n) / æblet

So yes, it does make things definite. It's just also a good way to see a word's gender, like attaching an article.

What is the gender of "kylling"?

[Xneb]

If you're in doubt of a word's gender, you can always look it up online (like here by the side of bøjning), Den Danske Ordbog also gives plurals to help you recognise irregular plurals

[PonyDesu]

Tak! Okay, -en is gender, -er is plural, but what's -erne?

[Xneb]

Definite plural (i.e. kyllingerne = the chickens)

[PonyDesu]

Ach, I see. Tak again! :)
