Learn Danish: Komikeren øver faktisk aldrig rigtig joken. - The comedian actually never really practices the joke.

When stacking central adverbs in the mid-field, Danish follows a general hierarchy: attitude or opinion first, then time or frequency, and finally degree or manner. Here, faktisk (attitude) comes first, followed by aldrig (frequency), and then rigtig (degree).

Could I put faktisk at the beginning of the sentence for emphasis?

Yes, you can say Faktisk øver komikeren aldrig rigtig joken. Notice that because Danish uses the V2 (verb-second) rule, moving faktisk to the front pushes the subject komikeren after the verb øver. The remaining adverbs, aldrig rigtig, stay in their normal mid-field position.

Why is it rigtig instead of the adverb form rigtigt?

When used as an adverb of degree meaning 'really,' it is very common in modern Danish to drop the -t ending. You will see both rigtig and rigtigt used this way, but leaving the -t off feels much more natural and colloquial when softening a negative statement like aldrig rigtig (never really).

How does a loanword like joken work with Danish grammar?

The word en joke is a fully integrated loanword from English. It acts exactly like a regular Danish common-gender noun (an en-word). To say 'the joke,' you simply attach the standard definite suffix -en to get joken.
