Questions & Answers about Jeg drikker mindre kaffe om aftenen.
Drikker is the present tense form of the verb at drikke (to drink).
- jeg drikker = I drink / I am drinking
- drik! = drink! (an imperative/command)
So in this sentence, drikker is correct because the speaker is making a normal statement, not giving an order.
Danish works like English here:
- mindre = less for uncountable things
- færre = fewer for countable things
Kaffe is usually treated as an uncountable noun, so:
- mindre kaffe = less coffee
Compare:
- mindre kaffe = less coffee
- færre kopper kaffe = fewer cups of coffee
Because kaffe is being used in a general, uncountable way.
In English, we also usually say:
- I drink less coffee in the evening not
- I drink less a coffee in the evening
So Danish does the same:
- mindre kaffe = less coffee
If you were talking about a specific coffee, the structure would be different, but here it just means coffee in general.
