Prenominal adjective: Kono, Sono, Ano, Dono
Kono, Sono, Ano, Dono are prenominal adjective.
- "Kono(この)" = This (right here near you)
- "Sono(その)" = This That (over there) further from you
- "Ano(あの)" = That (over there) further from you
- "Dono(どの)" = Which (of 3 or more objects)
Both "kono" and "kore" have the same meaning in English.
So if "kono" means "this" and "kore" means this, what is the difference in their uses?
The confusion comes from the fact that in English, the same word "this" is being used in 2 grammatically different sentences.
i.e."This(これ;kore) is a book" and "This(この;kono) book is expensive".
So a quick answer is: "kono", "sono", "ano" and "dono" are called pre-nominals and connect directly to a noun without any particles between the two.
