"Prodávám těchto dvě stě zajímavých knih."
Translation:I am selling these two hundred interesting books.
December 4, 2017
That is one of the peculiarities of the Czech number system. Maybe think of it like this:
- 200 is greater than 4, so it requires the “interesting books” to be in genitive plural (zajímavých knih).
- “These” (těchto) has to agree in case and number with zajímavých knih, even though it is placed before the “200.” (This is the hardest part for me; I always think about it too late.)
This case differs from the situation where the genitive is required by a preceding verb or preposition. Here the numeral would be put into the genitive as well.
