N5AI-draftedこれ/それ/あれ/どれ
this one / that one / that one over there / which one
Formation
これ/それ/あれ/どれ + は・が・を など(単独で名詞として使う)
Usage
These stand alone as pronouns for things. これ is near the speaker, それ is near the listener, あれ is far from both, and どれ asks 'which one' when choosing among three or more. Do not put a noun directly after them — use この・その・あの・どの for that. In conversation それ can also refer back to something just mentioned.
Examples
これは私のかばんです。
これはわたしのかばんです。
This is my bag.
それはいくらですか。
それはいくらですか。
How much is that?
あなたのかさはどれですか。
あなたのかさはどれですか。
Which one is your umbrella?
