Questions & Answers about Det er nemt at bruge en godbid når du træner.
Why is the adjective spelled nemt instead of nem here?
Because it describes the anticipatory subject Det, which is neuter. In Danish, adjectives must agree with the subject they describe, so nem (easy) gets a -t added to match Det. The actual thing that is easy is the action at bruge en godbid (to use a treat).
What is the role of at in this sentence?
at is the infinitive marker, exactly like the word "to" in the English phrase "to use". We need it to link the descriptive phrase Det er nemt (It is easy) to the base form of the verb bruge (use).
Where does the word godbid come from?
en godbid is a compound noun made of god (good) and bid (bite). It literally means "a good bite" but translates to "a treat", especially the kind you give to a pet while training.
Could I use da instead of når to mean "when" in this sentence?
No, because da is only used for a single, specific event in the past (like "when I was a child"). Since this sentence talks about a general, repeated action happening in the present (whenever you train), you must use når.
