In this lesson I’ll teach you how to use the Future Tense. I’ll also compare the Future Tense to the regular Present Tense, which we’ve been using so far to talk about the future. And you’ll learn how to use the Future Tense together with the Honorific Ending (으)시다.

Welcome back. In this lesson we're going to learn about the future tense.
So far we've learned the present tense and past tense.
Well, the future tense is used for talking about anything that will happen in the future.
So, the sentence, I go to Billy's house could become, I will go to Billy's house.
Or, Billy ate kimchi could become, Billy will eat kimchi.
Did you watch that movie? could become, Will you watch that movie?
And, I teach Korean could become, I will teach Korean.
Now before I talk about how to make the future tense, I should say that you might not always need the future tense.
And the present tense, as we've already learned, can kind of function like the future tense already.
For example, the sentence, 내일 파티에 가요.
Tomorrow I go to the party. Or, more naturally just, tomorrow I will go to the party.
However, whenever you want to emphasize that you will do something, and that you're not already doing it, use the future tense.
So here's an example of when you might want to use the future tense instead of just the present tense.
파티에 가요. I go to the party. Or this could mean, I will go to the party.
Now, without using the future tense, this sentence could mean either.
So you might want to use the future tense in this case to say that it's not happening today.
We can make the future tense by using the grammar form 거시다.
To do it, just get a verb stem. Then attach 을 if it ends in a consonant, or attach 리을 if it ends in a vowel.
And finally attach 거시다 and conjugate 이다. This will become 이에요.
Note that 거시다 is just from the words 것 meaning thing, and 이다 meaning to be.
And since 것 is more often shortened to just 거, this could instead become 거에요.
For example, 가다 could become 갈 거예요.
And 먹다 could become 먹을 거예요.
Here are two sentence examples.
어제 선생님을 만났어요. I met the teacher yesterday.
내일 선생님을 만날 거예요. I will meet the teacher tomorrow.
Let's talk a little bit more about that verb 이다, to be.
In the future tense, 이다 becomes 일 거예요, just like normal.
For example, 내일의 모임은 여기일 거예요. Tomorrow's meeting will be here.
However, 일 거예요 cannot be used to say that you, or any noun, will become something.
For example, you couldn't use 일 거예요 to say that you will become, be, a teacher or an astronaut when you get older.
We'll learn how to say to become with a different verb in a later lesson.
All right, so now I want to have you do some practice on your own.
Here are six sentences that are written with the present tense.
I want you to change them all to the future tense.
You can pause the video here until you're ready, and then click resume.
Here are the answers.
내일 현우 씨도 초대할 거예요. Tomorrow I will also invite 현우.
빌리 씨도 아주 건강할 거예요. Billy also will be very healthy.
저는 너무 바쁠 거예요. I will be too busy.
저도 차를 많이 마실 거예요. I will also drink a lot of tea.
이제 가방을 살 수 있을 거예요. Now I will be able to buy a bag.
저는 제 방에 갈 거예요. I will go to my room.
내일 현우 씨도 초대할 거예요. 내일 현우 씨도 초대할 거예요.
빌리 씨도 아주 건강할 거예요. 빌리 씨도 아주 건강할 거예요.
저는 너무 바쁠 거예요. 저는 너무 바쁠 거예요.
저도 차를 많이 마실 거예요. 저도 차를 많이 마실 거예요.
이제 가방을 살 수 있을 거예요. 이제 가방을 살 수 있을 거예요.
저는 제 방에 갈 거예요.
There is an exception when you're using this future tense 거시다 with verb stems that end with a 비읍 or with a 리을.
If the verb stem ends with a 비읍, you're going to remove that first, and then attach 우, followed by 리을, and then 거시다 as usual.
For example, 춥다 would become 추울 거예요.
Or if the verb stem ends with a 리을, you'll simply attach 거예요.
So 팔다 would become 팔 거예요.
And there are more verbs with conjugation exceptions, as there are for any rule, and I'll explain those later as they come up.
But before we go, a quick note about using the honorific verb ending 으시다.
In the future tense, this will become 으실 거예요 when it comes after a consonant, or just 실 거예요 when it comes after a vowel.
Here are two examples.
우리 할머니도 중국어를 공부하실 거예요.
My grandmother also will study Chinese.
선생님은 나가실 거예요?
Will the teacher go outside?
And we'll do more practice with this 으시다 ending in later lessons.
So in this lesson we've now finished learning about the future tense, as well as how to use the honorific ending in the future tense, and some exceptions with using it.
So practice everything in this lesson, and I'll see you again next time.
그럼 다음에 또 봐! Well then, see you again next time!
