Questions & Answers about gyedaneul georeo ollagaya haeseo jogeum pigonhaeyo.

What is the function of the particle 을 in 계단을?

계단 means “stairs,” and -을 is the direct-object marker in Korean. By attaching -을, you indicate that the stairs are what you’re “walking up.” So 계단을 걸어 올라가다 literally means “to walk up (the) stairs.”

Why is 걸어 placed before 올라가야, and what’s the difference between 걸어 and 걸어서?

걸어 올라가다 is a combination of two verbs: 걷다 (to walk) in its adverbial form 걸어 + 올라가다 (to go up). Together they mean “to walk up.”

• 걸어서 올라가다 is equally correct and means “by walking, to go up.”
• In casual speech, Koreans often shorten 걸어서 to 걸어, but both forms function as adverbials modifying 올라가다.

What does the grammar pattern -아/어야 해서 mean? How is it built?

-아/어야 해서 = -아/어야 하다 (must do ...) + -서 (because/so).
Breakdown:

1. 걸어 올라가야 하다 = “must walk up”
2. Change -하다 to -해서 to link the reason
   → 걸어 올라가야 해서 = “because I have to walk up ...”

How is -아/어야 해서 different from the simpler cause-connector -아서/어서?
