How do you say "by the way" in Korean?
So I'm looking for how to add "by the way" in a sentence.
People often say it's "근데", but isn't that more like "but"?
Let's say you're talking with your friend, and then suddenly you remember "oh yeah, I saw that movie yesterday by the way" - A movie you talked about before maybe, or something in that style.
Here saying "근데 어제 그 영화를 봤어" feels more like "but I watched that movie yesterday"
So what would be a more appropriate word?

Question

Answer

'그나저나' is the right expression

Answer

You could use the phrase '~거든(요)' at the end of a verb stem. It gives the meaning of 'F.Y.I' or "just so you know" etc. For example,

선생을 싫어하거든요.
F.Y.I, I hate fish.

나는 미국사람 이거든.
Just so you know, I am an American.

Or you can use the word 그런데.
