Learn Hardcore Korean: naeil hoesa-e keopireul gajyeool geoyeyo. - I’m going to bring coffee to the office tomorrow.

-을 거예요 attaches to a verb stem to indicate that the action will happen in the future or that you plan/intend to do it. Here, 가져오 (the stem of 가져오다) + ㄹ 거예요 = 가져올 거예요, meaning “(I) will bring.”

When do you add -ㄹ versus -을 before 거예요?

It depends on the final sound of the verb stem:

If the stem ends in a vowel (가져오-), you add -ㄹ → 가져올.
If it ends in a consonant (먹-, 쓰-), you add -을 → 먹을 거예요, 쓸 거예요.

Why is 가져오다 (“to bring”) used here instead of 가져가다 (“to take”)?

It’s all about perspective:

가져오다 means “to bring [something toward the speaker or listener’s location].”
가져가다 means “to take [something away from the speaker or listener’s location].”
Since you’re talking about bringing coffee to the company (where you or your coworkers will be), you use 가져오다.

Why is the particle 에 used after 회사 rather than 에서?

회사에 marks the destination of motion (where you’re bringing the coffee).
회사에서 would mark the starting point or location of an action.
Because you’re going to the company to deliver coffee, you use 에 for “to the company.”

What role does 커피를 play in the sentence?

커피 is the direct object (“coffee”), and -를 is the object particle that flags it as what’s being brought. In casual speech you might drop it (“커피 가져올 거예요”), but formally it’s 커피를 가져올 거예요.

There’s no subject like 저는—why is that omitted?

Korean often omits subjects when they’re clear from context. Here, “I” is understood. You could say 저는 내일 회사에 커피를 가져올 거예요, but it’s redundant if everyone knows who’s talking.

The order is 내일 회사에 커피를 가져올 거예요. Can you reorder these elements?

Korean is fairly flexible, but the neutral order is:

Time (내일)
Place/destination (회사에)
Object (커피를)
Verb phrase (가져올 거예요)
You could say 내일 커피를 회사에 가져올 거예요 for slight emphasis on coffee, but you wouldn’t swap the verb to the middle or move “내일” to the end without changing nuance.

How is 거예요 pronounced in natural speech?

거예요 often contracts to 꺼예요, sounding like [가저올 꺼예요]. In fast colloquial speech it can even go down to [가저올 꺼야]. In writing, though, you still spell 거예요.

What’s the difference between -을 거예요 and -을게요?

-을 거예요 simply states a future action or plan.
-을게요 implies a promise or decision made in response to something (e.g., “If that’s what you need, I’ll do it”).
In neutral planning (“I will bring coffee”), you use -을 거예요. Use -을게요 if you’re offering or assuring someone on the spot.
