N4 Reporting Speech
こ/そ/あ: meaning, usage and examples
こ/そ/あ means: to refer to things not visible to the speaker or the hearer.
How to form it
そ: something only one person knows or just mentioned (その人, それ) / あ: something both people know (あの店, あれ)
Examples
A:この話、聞いた?B:うん、聞いた。
A: Did you hear this story? B: Yes, I heard.
その件について、後で話しましょう。
Let's talk about that matter later.
昨日の映画、あれはおもしろかったですね。
That movie yesterday was really good, wasn't it?
A:駅の前に新しい店ができました。B:その店は何の店ですか。
A: A new shop opened in front of the station. B: What kind of shop is it?
When to use it
こ, そ and あ can point to things not in front of you, such as things in a conversation or memory. Use そ for something just mentioned, or something only one of you knows: A:山本さんという人に会いました。B:その人はどんな人ですか. Use あ for something you and the listener both remember: 昨日の映画、あれはおもしろかったですね.
Nuance
Neutral. Using あ for something the listener does not know sounds odd, because あ assumes shared memory. こ can point to something the speaker is about to say or has just said and feels close to: この話は秘密です. In writing, そ is the usual choice for what came before.
Compare
With visible things, こ/そ/あ is about distance: これ (near me), それ (near you), あれ (far from both). In conversation it is about knowledge: その人 (you mentioned him, I do not know him) vs あの人 (we both know him).
Tip: If the listener cannot know the thing, use そ. Save あ for "you know the one".
