Learn Hardcore Norwegian: Læreren deler ut frukt til barna etter timen. - The teacher hands out fruit to the children after class.

Deler ut is the Norwegian equivalent of “to hand out” or “to distribute.” It’s a so-called two‐word verb (sometimes called a particle verb) consisting of the verb dele (“to share”) plus the particle ut (“out”). In a simple sentence like this they stay together:
Læreren deler ut frukt…
But if you replace the object with a pronoun, you split them:
Læreren deler dem ut.

Why is there no article before frukt?

In Norwegian frukt can be a mass noun (like “fruit” in English) referring to fruit in general or to unspecified pieces of fruit. Mass nouns don’t need an indefinite article. If you wanted to talk about a single piece of fruit, you’d say en frukt (“a piece of fruit”). If you meant “specific pieces” you could use the plural countable form frukter (“fruits”), but that slightly changes the nuance.

Why is læreren written with an –en ending?

The ending –en is the definite article attached to the noun in Norwegian Bokmål.
lærer = “a teacher” (indefinite)
læreren = “the teacher” (definite)
