Questions & Answers about Er hat die laktosefreie Milch nicht gekauft.
Why is nicht placed right before gekauft instead of earlier in the sentence?
In German, when you want to negate the entire action (meaning he simply did not do it), nicht gets pushed to the end of the clause. However, because this sentence is in the perfect tense, the past participle gekauft claims the absolute final spot. Therefore, nicht goes as close to the end as it can get: right before the participle.
Would the meaning change if I said Er hat nicht die laktosefreie Milch gekauft?
Yes, it would change completely! Putting nicht directly in front of the noun phrase die laktosefreie Milch negates only that specific part. It means he didn't buy the lactose-free milk, strongly implying he bought something else, like regular milk instead. By putting nicht at the end before the verb, you are just stating the action of buying did not happen.
Why does the adjective laktosefreie end in -e here?
Milch is feminine, and in this sentence it is the direct object (accusative case). Because the definite article die already clearly shows the gender and case, the adjective just gets the weak ending, which is -e for feminine accusative.
