"She has small children."
Translation:Zij heeft kleine kinderen.
No, but Klein is a very old surname of German origin that spread throughout central Europe and beyond, so I'm sure some Dutch people have this last name. His dad was Austrian, his mom Hungarian, and they were Jewish.
The notes say "If no article at all comes before a het-word, then the adjective does not get the -e ending either". Since that "Kind" is a het-word, I expected "klein kinderen" to be correct. Why isn't it? What is the correct note's section I should have read not to commit this mistake?
