Comparison with Other Connectives

• -아서/어서/해서: Indicates reason or cause. Unlike -는/은 데, it cannot express contrast.

  • Example: 배가 고파서 밥을 먹었어요. (I was hungry, so I ate food.)

• -지만: Specifically used for contrast, equivalent to "but/however" in English.

  • Example: 바쁘지만 갈 거예요. (I'm busy, but I will go.)

• -니까: Also indicates reason or cause, often used for commands or suggestions.

  • Example: 시간이 없으니까 빨리 갑시다. (Since we don't have time, let's go quickly.) -는/은 데 is more versatile as it can imply background information, contrast, or an unexpected result.
