kurām
"Kurām" is the dative plural form of "kura," meaning "to which" or "for which" (feminine).
In this sentence, 'kurām' is used as a relative pronoun referring to the books, agreeing in number and gender.
Šīs ir grāmatas, kurām ir visvairāk lasītāju.
These are the books that have the most readers.
Here, 'kurām' serves as a relative pronoun linked to 'cilvēkiem' (people), showing dative plurality.
Es runāšu ar cilvēkiem, kurām ir laiks palīdzēt.
I will talk to the people who have time to help.
In this case, 'kurām' connects the noun 'idejas' (ideas) with the clause describing those ideas, in dative plural to maintain agreement.
