Grammar · Question words

どの, どれ and どちら, which

The pattern

dono [noun] / dore / dochira

どの comes before a noun, どれ stands alone among three or more, どちら chooses between two and is also the polite 'where'.

The mistake to avoid

This mirrors この / これ exactly. If you know one set you already know the other.

Examples

dono hon desu ka.
Which book?

Which one do you like?
dochira ga ii desu ka.
Which one is better?
dono hito ga tanaka-san desu ka.
