3. Comparative Analysis

While (으)ㄴ/는데 often translates to "but" or "however," it's important to distinguish it from other conjunctions like 하지만, 그러나, and 그런데.

• 하지만/그러나: Used strictly for contrast meaning "but" or "however" between two sentences.

  Example:

  비가 와요. 하지만/그러나 갈 거예요.
  (It's raining. But I'll go.)
  

• (으)ㄴ/는데: More versatile; links clauses within a sentence and can express contrast, background, or unexpected results. Example:

  비가 오는데 갈 거예요.
  (It's raining, but I'll go.)
