Korean Future Tense for Beginners: -(으)ㄹ 거예요 Made Easy

English learners often call this the “Korean future tense,” and that label is useful at the beginner stage. Korean, however, does not force every future idea into one rigid tense form. The construction -(으)ㄹ 거예요 -(eu)l geoyeyo will / be going to is especially useful because it can describe a future plan, a speaker's intention, or a prediction about what is likely to happen.

The Korean-English Learners' Dictionary explains that 거 geo bound noun used in several spoken constructions can express a speaker's guess or conviction and notes that this use commonly appears in -을 거다 -eul geoda will / likely to constructions. King Sejong Institute's beginner grammar practice also treats 갈 거예요, 읽을 거예요, 먹을 거예요, 만들 거예요, and 운동할 거예요 as standard beginner forms.

What -(으)ㄹ 거예요 Really Means

The form -(으)ㄹ 거예요 -(eu)l geoyeyo will / be going to points the listener toward a future situation. The most natural English translation depends on what the speaker is doing with the sentence.

It can express a plan

When you are talking about something you have already decided to do, the construction naturally sounds like “be going to” in English. For example, 주말에 부산에 갈 거예요 jumare Busane gal geoyeyo I am going to go to Busan this weekend describes a future plan.

It can express an intention

A future sentence can also focus on what the speaker intends to do. The form itself does not need a separate Korean word meaning “intend.” The context supplies that interpretation.

It can express a prediction

The same construction is not limited to your own actions. It can describe what you expect to happen. In 내일 비가 올 거예요 naeil biga ol geoyeyo It will rain tomorrow, the speaker is making a prediction.

Learn the function, not one fixed English translation

A personal plan may be translated with “be going to,” while a prediction may sound better with “will” or “probably will.” The Korean form does not change simply because English chooses a different auxiliary verb.

The Three Conjugation Patterns You Need

The key decision is not the English meaning of the verb. Look at the final sound of the Korean verb stem. Beginners need three patterns: a stem ending in a vowel, a stem ending in a consonant other than ㄹ, and a stem already ending in ㄹ.

Step 1: Remove 다 and find the stem

Step 2: Match the stem ending to the correct form

Step 3: Keep 거예요 separate in standard spacing

Write 갈 거예요 gal geoyeyo will go, 먹을 거예요 meogeul geoyeyo will eat, and 할 거예요 hal geoyeyo will do with a space before 거예요.

This rule is different from -아요/-어요

In the present tense, beginners often choose between -아요 -ayo polite present pattern and -어요 -eoyo polite present pattern by looking at the stem vowel. With -(으)ㄹ 거예요 -(eu)l geoyeyo future pattern, the beginner decision is based on whether the stem ends in a vowel, a consonant, or ㄹ.

Vowel-Ending Stems: Add -ㄹ 거예요

When a verb stem ends in a vowel, attach -ㄹ 거예요 -l geoyeyo will / be going to. The ㄹ becomes the final consonant of the last syllable of the stem.

가다 becomes 갈 거예요

The stem of 가다 gada to go is 가 ga go- stem. It ends in a vowel, so the result is 갈 거예요 gal geoyeyo will go / am going to go.

보다 becomes 볼 거예요

The stem 보 bo see/watch- stem ends in a vowel. Therefore, 보다 boda to see / to watch becomes 볼 거예요 bol geoyeyo will see / will watch.

마시다 becomes 마실 거예요

The stem of 마시다 masida to drink is 마시 masi drink- stem. The result is 마실 거예요 masil geoyeyo will drink.

배우다 becomes 배울 거예요

The stem 배우 baeu learn- stem ends in a vowel, so 배우다 baeuda to learn becomes 배울 거예요 baeul geoyeyo will learn.

Consonant-Ending Stems: Add -을 거예요

When a verb stem ends in a consonant other than ㄹ, use -을 거예요 -eul geoyeyo will / be going to. The extra vowel makes the ending easier to attach after a consonant.

먹다 becomes 먹을 거예요

Remove 다 da dictionary ending from 먹다 meokda to eat. The stem 먹 meok eat- stem ends in a consonant, so the result is 먹을 거예요 meogeul geoyeyo will eat / am going to eat.

읽다 becomes 읽을 거예요

The stem of 읽다 ikda to read is 읽 ik read- stem. It ends in a consonant, so the polite future form is 읽을 거예요 ilgeul geoyeyo will read.

받다 becomes 받을 거예요

With 받다 batda to receive, the stem 받 bat receive- stem ends in a consonant. Therefore, 받을 거예요 badeul geoyeyo will receive is the expected form.

Keep the final consonant

Do not remove the final consonant from the stem. Keep the full stem and attach the ending: 먹 → 먹을 거예요 meok → meogeul geoyeyo eat- stem → will eat.

하다 and Verbs Whose Stems Already End in ㄹ

Two groups deserve special attention because they appear frequently in beginner Korean: verbs built with 하다 hada to do and stems that already end in ㄹ l final ㄹ consonant.

하다 becomes 할 거예요

The stem 하 ha do- stem ends in a vowel, so 하다 hada to do becomes 할 거예요 hal geoyeyo will do / am going to do.

살다 becomes 살 거예요

The stem of 살다 salda to live is 살 sal live- stem. It already ends in ㄹ, so the correct form is 살 거예요 sal geoyeyo will live.

Put the pattern into complete sentences

The ㄹ rule saves you from over-conjugating

Beginners often see a consonant at the end of 살 sal live- stem and automatically add 을. The existing ㄹ is a special case. Keep it and move directly to 거예요 geoyeyo future-construction element.

Plans, Intentions, and Predictions

The grammar form stays the same, but the communicative purpose changes with the subject and context. Instead of trying to assign one English tense to every example, ask whether the sentence presents a plan, an intention, or a prediction.

Use it for a personal plan

Use it for an intention or decision

When the speaker describes what they intend to do from now on, the same construction can sound like a decision about future behavior.

Use it for a prediction

With weather, another person's future action, or a situation outside the speaker's direct control, the construction often expresses a prediction.

The same Korean form can produce different English wording

Both sentences use -(으)ㄹ 거예요 -(eu)l geoyeyo future-related construction. The difference comes from what is being described.

Questions, Negatives, and Time Words

Once the basic future form is familiar, you can immediately turn it into questions and negative sentences. Korean does not need a separate helping verb equivalent to English “will” or “do.”

Questions can keep the same future form

In speech, intonation helps show that the second sentence is a question. In writing, the question mark does the same job. The form 만날 거예요 mannal geoyeyo will meet / be going to meet itself does not need to change.

Use 안 for a simple negative future sentence

With many action verbs, a beginner can put 안 an not before the verb phrase and keep the future construction.

Future time words make the sentence easier to process

Memorize reusable future questions

Common Beginner Mistakes with -(으)ㄹ 거예요

Most beginner errors happen because learners skip the stem step, apply the vowel-ending form everywhere, forget the ㄹ-ending special case, or write the construction with the wrong spacing.

Mistake 1: Keeping 다

Mistake 2: Using -ㄹ 거예요 after every stem

Consonant-ending stems need -을 거예요 -eul geoyeyo future pattern after a consonant. That is why 먹다 → 먹을 거예요 meokda → meogeul geoyeyo to eat → will eat.

Mistake 3: Adding 을 after a stem already ending in ㄹ

Remember 살다 → 살 거예요 salda → sal geoyeyo to live → will live. The existing ㄹ stays in place.

Mistake 4: Writing 거예요 without a space

Mistake 5: Assuming the pattern only means a personal plan

Compare 저는 내일 서울에 갈 거예요 jeoneun naeil Seoure gal geoyeyo I am going to Seoul tomorrow with 내일 비가 올 거예요 naeil biga ol geoyeyo It will rain tomorrow. The first is a plan. The second is a prediction.

Mistake 6: Treating every future expression as interchangeable

Korean has other future-related expressions. You may later meet -고 싶어요 -go sipeoyo want to, -(으)려고 해요 -(eu)ryeogo haeyo intend / plan to, and -(으)ㄹ게요 -(eu)lgeyo I will, often as a speaker's decision or commitment. They can all point toward the future, but they do not carry exactly the same conversational function.

Frequently Asked Questions About the Korean Future Tense

Korean Future Tense: Let the Stem Ending Guide You

The Korean future pattern becomes much easier when you stop memorizing 갈 거예요 gal geoyeyo will go, 먹을 거예요 meogeul geoyeyo will eat, and 할 거예요 hal geoyeyo will do as three unrelated forms.

Start with the dictionary form and remove 다 da dictionary ending. A vowel-ending stem takes -ㄹ 거예요 -l geoyeyo future pattern after a vowel. Most consonant-ending stems take -을 거예요 -eul geoyeyo future pattern after a consonant. If the stem already ends in ㄹ, keep that ㄹ and add 거예요.

Then turn the rule into your own sentences. Ask where you are going tomorrow, what you are going to eat, what you will do this weekend, and what you expect to happen next week. Reusing familiar verbs across present, past, and future makes the tense system easier to see and much easier to remember.
