Learn Danish: Danseren skal øve koreografien en del. - The dancer must practice the choreography a good deal.

While skal can sometimes indicate future tense, its primary meaning in Danish is obligation or necessity, corresponding to "must" or "have to" in English. Here, it clearly shows that practicing is a strict requirement for the dancer rather than just a future event.

Does en del literally mean "a deal"?

Literally, en del translates to "a part." However, it is widely used as a fixed expression meaning "a good deal," "quite a bit," or "a lot." In this sentence, it functions as an adverbial phrase describing the extent of the practice.

Why does the loanword koreografi take the -en suffix?

As a general rule in Danish, abstract loanwords ending in -i (like koreografi, energi, or filosofi) take the common gender (en). Therefore, the definite form ("the choreography") simply takes the -en suffix to become koreografien.

Could we change the word order to: Danseren skal øve en del koreografien?

No, that would sound unnatural. In standard Danish main clauses, the direct object (koreografien) is placed directly after the main verb (øve). Adverbial phrases that describe the extent or degree of the action (en del) belong at the very end of the clause.
