How to say "You promised to teach me"?
Hi!
How to say "You promised to teach me" in japanese?

Question

Answer

The most common way to say this is
"教えてくれる約束ですよね"
(Oshietekureru yakusoku desuyone)

But it depends on the context.

Answer

I think you can say something like this.

(あなたは)  わたしに   日本語 を   教えようと      約束       しましたん   ですよ .
(anatawa) watashi ni  nihongo wo  oshieyouto   yakusoku shimashitan desuyo.

(あなたは)    わたしに     日本語を       教えようと        約束       しました   んですよ .
　You              to me       Japanese         to teach       promise         made     (ending)

But maybe someone will present a better sentence (I am not a native Japanese speaker).
