korya, sorya, arya こりゃ, そりゃ, ありゃ

In Japanese, korya, sorya, arya こりゃ, そりゃ, ありゃ are contractions of kore, sore, are これ, それ, あれ marked as the topic by the wa は particle.

For example: nanda korya なんだこりゃ means the same thing as nanda kore wa なんだこれは, "what is this?!" See also: nani kore なにこれ and emotive right-dislocation.

Interrogative pronouns, like dore どれ, can't be marked as the topic, so there's no contraction for dore wa どれは. However, the word dorya どりゃ does exist, and it does come from dore どれ, but its usage is different.

The word dorya is used to say "how do you like that!" when someone just did something, or will do something. In anime, it's generally used after a character attacks another, and then it's translated as "take that!" or something similar.
