Text: Kono, Sono, Ano, DonoText: Kono, Sono, Ano, Dono by LearningJapanese
この, その, あの, どの + noun
Kono, sono, ano, dono + noun
Try not to get these confused with 'kore, sore, are, dore' as they are similar (so I refer you back to the previous tutorial: http://learningjapanese.deviantart.com/art/Text-Kore-Sore-Are-Dore-266472391) but their uses are different. These can make a sentence slightly more specific and must always be followed by a noun (whereas 'kore, sore, are, dore' must always be alone).
Kore wa ikura desu ka?
How much is this?
Replace 'kore wa' with 'kono+noun':
Kono kaban wa ikura desu ka?
How much is this bag?
Notice that the subject marker moved. It's not after 'kono' as the 'no' series has to have a noun after it; rather it is after the noun as the noun is now the subject of the sentence.
