Questions & Answers about En del af skærmene var knap så slidstærke.
How does knap så change the meaning compared to just saying ikke slidstærke?
Using ikke slidstærke (not wear-resistant) is an absolute statement. Using knap så (not quite as / less) softens the degree. It implies the screens had some durability, but they fell short of the expected standard.
Does the adjective still change its ending when following knap så?
Yes. Even though it is modified by knap så, the adjective must still agree with the noun it describes. Because the subject here refers to multiple screens (skærmene), the adjective takes the plural -e ending to become slidstærke.
Does en del af just mean "one part of" the screens?
It can mean literally "a part of", but in Danish en del is very frequently used as a quantifier meaning "a good deal", "quite a few", or "several". Here, it means a significant number of the screens had this issue.
How is the word slidstærke built?
It is a compound adjective made from the noun slid (wear and tear) and the adjective stærk (strong). Literally meaning "wear-strong", it is the standard Danish way to say "wear-resistant" or "durable".
