Express an intention rather than a completed event
내일 도서관에 가려고 해요 says the speaker intends to go to the library tomorrow. The intention concerns an action that has not been asserted as completed. The final 해요 makes the statement an ordinary polite utterance. The listener can understand the plan without treating it as an accomplished trip.
The construction is useful when describing what you have in mind or are preparing to do. It does not require a formal promise. If the plan changes, the earlier intention statement may still have been accurate. Distinguish the truth of the intention at the time of speaking from the later success of the plan.
Start with an action the speaker can reasonably intend, such as studying, meeting a friend, or making a meal. At later levels the construction has other contextual uses, but these first examples keep a human actor and a controllable action. That scope prevents a learner from treating every sentence about the future as an intention.
내일 도서관에 가려고 해요.
I intend to go to the library tomorrow.
The sentence states a plan without asserting the trip is complete.
오늘은 집에서 공부하려고 해요.
I intend to study at home today.
The location belongs to the intended studying action.

Choose the form from the stem ending
Remove the dictionary ending 다 and inspect the stem. A vowel stem takes 려고: 가다 becomes 가려고. A consonant stem such as 먹, from 먹다, takes 으려고, giving 먹으려고. A rieul stem keeps its rieul and takes 려고: 만들다 becomes 만들려고.
Do not apply rieul deletion from another ending automatically. The form 만들려고 retains the stem’s rieul before the following rieul. Korean stem behavior depends on the particular ending environment. Learning one deletion pattern in a 세요 form does not authorize deleting the consonant in every later construction.
The ending attaches to the stem, not the complete polite form. 먹어요려고 would combine incompatible pieces. A useful written check is to show the dictionary form, the bare stem, and the intended construction on separate lines. Then read the final complete sentence naturally so that the analysis supports speaking rather than replacing it.
저녁을 먹으려고 해요.
I intend to eat dinner.
The consonant stem takes 으려고.
카레를 만들려고 해요.
I intend to make curry.
The rieul stem retains its consonant in this pattern.
Build a rieul stem intention
Say you intend to make dinner.
- Start from 만들다.
- Keep the rieul and add 려고.
- Add the dinner object and final 해요.
저녁을 만들려고 해요.
Use the intended action as a purpose clause
The intention clause can come before a real preparatory action. 책을 읽으려고 도서관에 갔어요 means the speaker went to the library intending to read a book. The first clause supplies the purpose; the second reports the trip. The reading itself has not been independently asserted as completed.
In these straightforward purpose sentences, keep the intended actor consistent. The person who goes to the library intends to read. If two different people are involved, a more explicit construction may be needed to show who wants whom to do what. This lesson avoids hiding a subject change inside an otherwise simple purpose pattern.
The ordinary particles, short words attached to the end of a noun to show its role in the sentence, remain in each clause. The book is the object of reading and takes 을; the library is the destination of going and takes 에. Do not let the new connector erase those relationships. Build each action with its own participants first, then connect the purpose to the preparation.
책을 읽으려고 도서관에 갔어요.
I went to the library to read a book.
The trip is asserted; the intended reading supplies its purpose.
친구를 만나려고 카페에 갔어요.
I went to a café to meet a friend.
Meeting takes the friend as its object, while the café is the destination.
Explain a preparatory trip
Say you went to the library to study.
- Build the intended action 공부하려고.
- Use 도서관에 as the destination.
- Make the actual trip past with 갔어요.
Compare your reasoning
공부하려고 도서관에 갔어요.
Distinguish purpose from an ordinary reason
A purpose looks forward to an intended goal: buying ingredients to cook. A reason can explain an event through an existing circumstance: being hungry, so eating. Both answer the question “why,” but they organize the relationship differently. The 려고 construction presents what the actor aims to do.
For a simple reason, patterns with 아서 or 어서, or with 으니까, may be appropriate. Do not replace them mechanically with 려고. A description such as being cold is not the same as intending to be cold. Identify whether the first clause is a goal or a circumstance before choosing the connector.
A preparation can fail to achieve its purpose. Someone can buy vegetables to make dinner and then change plans. The purpose statement remains about the motivation for the purchase. If the outcome matters, add a sentence reporting what actually happened. This keeps an intended result from being mistaken for a factual result in a short narrative.
요리하려고 채소를 샀어요.
I bought vegetables to cook.
The cooking is the intended goal of the purchase.
배가 고파서 밥을 먹었어요.
I ate because I was hungry.
Hunger is a circumstance explaining eating, not an intended action.
Keep wishes, abilities, and intentions separate
가고 싶어요 expresses wanting to go. 갈 수 있어요 expresses being able to go. 가려고 해요 expresses intending to go. A person can want something without planning it, plan something despite reluctance, or be able to do something without choosing it. These are separate claims about the same action.
A plan becomes more informative when the practical constraints are clear. If you intend to study but cannot use the library today, the intention does not erase that obstacle. A following contrast can explain the situation. At this level, two short sentences are enough to keep the desire, plan, and ability claims distinct.
When interpreting another person’s message, do not infer a commitment from every wish. A friend saying they want to travel may be describing an aspiration. Ask about the actual plan when coordination depends on it. The lesson’s practice therefore gives concrete contexts rather than asking for one translation of all three expressions.
여행하고 싶어요.
I want to travel.
This states a wish without automatically making a plan.
이번 주에는 갈 수 없어요.
I cannot go this week.
This reports a practical limitation, even if a desire exists.
Recognize 겠 as more than a future tense
The element 겠 appears in expressions of intention and of conjecture (a guess based on what the speaker sees or knows), and in conventional polite expressions. 제가 하겠습니다 can present the speaker’s willingness to do a task in a formal setting. It is not simply a future tense that must replace every present ending whenever a sentence mentions tomorrow.
A sentence such as 맛있겠어요 can mean that something looks as if it will be delicious, or more naturally in context that it looks delicious. The speaker is making a judgment. The subject is not intending to become delicious. That contrast shows why the function of 겠 must be interpreted from the predicate it attaches to, the verb or description that ends the sentence, and from the situation.
This lesson asks you to recognize these broad uses while producing the transparent 려고 intention pattern. It does not treat all the Korean forms for future events and for guesses based on evidence as one interchangeable set. When precision matters, use a construction whose meaning you can explain and a time expression that identifies when the intended action is relevant.
제가 하겠습니다.
I will do it.
In the stated formal offer, 겠 expresses the speaker’s willingness.
맛있겠어요.
It looks delicious.
The context supports a judgment, not a plan by the food.
State a plan with realistic conditions
A plan may depend on a condition. 시간이 있으면 공부하려고 해요 says the speaker intends to study if time is available. The conditional clause does not assert that the time already exists. Keep the uncertainty visible when it matters to the listener’s expectations.
For the practice game, first classify the message as a wish, ability, intention, purpose, or judgment. Next identify the stem ending. This order prevents a perfectly formed 려고 phrase from being used for the wrong relationship. The feedback explains why a wrong choice may be grammatical but still fail the particular scenario.
For independent production, name one realistic intention and one action you took toward a goal. Use a specific place or object so that the sentence says something beyond “I intend to do it.” On a later day, recall one vowel stem, one consonant stem, and one rieul stem. Check both the form and whether the intended event is being claimed as complete.
시간이 있으면 책을 읽으려고 해요.
If I have time, I intend to read a book.
The condition keeps the availability of time open.
공부하려고 책을 샀어요.
I bought a book to study.
The purchase is real in the account; studying is its purpose.
Notice the difference
Common mistakes
Use the linking vowel after this consonant stem
Instead of먹려고 해요.
For this meaning먹으려고 해요.
The stem 먹 ends in a consonant, so it takes 으려고.
Do not delete rieul in this environment
Instead of만드려고 해요.
For this meaning만들려고 해요.
The rieul remains before 려고.
A wish is not an intention statement
Instead of가고 싶어요.
For this meaning가려고 해요.
For the stated meaning “I intend to go,” use the intention construction.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
State an intention to meet a friend tomorrow.
Compare with a model
내일 친구를 만나려고 해요.
I intend to meet a friend tomorrow.
The vowel stem takes 려고, and the friend remains the object of meeting.
- Future time expression
- Correct stem form
- Clear intended action
Your turn 2
Explain that you bought vegetables to make curry.
Compare with a model
카레를 만들려고 채소를 샀어요.
I bought vegetables to make curry.
The rieul stays in the purpose form, and the final past verb asserts the purchase.
- Rieul retained
- Goal before preparation
- Past purchase

Make the next choice.
Choose a response and learn why it works. Your score reflects your first answer to each question. You can revisit anything you miss.
Choose an answer, then open the explanation to check your reasoning.
Question 1
Which statement explicitly presents an intention?
- 내일 가려고 해요.
- 어제 갔어요.
Check the answer
Answer: 내일 가려고 해요.
내일 가려고 해요.: 려고 해요 presents what the speaker plans to do.
어제 갔어요.: This reports a past trip.
Question 2
Does an intention statement prove the event later occurred?
- Yes, completion is part of the ending.
- No, the plan and its outcome are separate.
Check the answer
Answer: No, the plan and its outcome are separate.
Yes, completion is part of the ending.: It does not guarantee later completion.
No, the plan and its outcome are separate.: The construction reports an intended action.
Question 3
Build “intend to eat” from 먹다.
- 먹으려고 해요.
- 먹려고 해요.
Check the answer
Answer: 먹으려고 해요.
먹으려고 해요.: The consonant stem takes 으려고.
먹려고 해요.: The required linking 으 is missing.
Question 4
Build “intend to make” from 만들다.
- 만드려고 해요.
- 만들려고 해요.
Check the answer
Answer: 만들려고 해요.
만드려고 해요.: This incorrectly deletes the stem’s rieul.
만들려고 해요.: The rieul remains before 려고.
Question 5
In the reading example, which event is explicitly reported as completed?
- Going to the library
- Finishing the book
Check the answer
Answer: Going to the library
Going to the library: The final past predicate asserts the trip.
Finishing the book: The purpose clause does not assert successful completion.
Question 6
Choose the phrase for “to meet a friend.”
- 친구에서 만나려고
- 친구를 만나려고
Check the answer
Answer: 친구를 만나려고
친구에서 만나려고: 에서 is not the object particle for the friend.
친구를 만나려고: 만나다 takes the friend as an object in this pattern.
Question 7
You bought vegetables with cooking as your goal. Choose the connector.
- 요리하려고 샀어요.
- 요리해서 샀어요.
Check the answer
Answer: 요리하려고 샀어요.
요리하려고 샀어요.: 려고 explicitly marks the intended purpose.
요리해서 샀어요.: The 해서 connection does not express the stated goal in this sentence.
Question 8
Which distinction matters before choosing 려고?
- Whether the sentence is long or short
- Goal versus existing reason
Check the answer
Answer: Goal versus existing reason
Whether the sentence is long or short: Length does not determine purpose grammar.
Goal versus existing reason: The intended relationship determines the construction.
Question 9
Which expression names ability rather than intention?
- 갈 수 있어요.
- 가려고 해요.
Check the answer
Answer: 갈 수 있어요.
갈 수 있어요.: 수 있어요 expresses possibility or ability.
가려고 해요.: 려고 해요 expresses the plan.
Question 10
Does wanting to travel automatically establish a travel arrangement?
- Yes, the listener can assume bookings exist.
- No, a wish can exist without a concrete plan.
Check the answer
Answer: No, a wish can exist without a concrete plan.
Yes, the listener can assume bookings exist.: The wish does not assert any booking.
No, a wish can exist without a concrete plan.: Desire and preparation are different facts.
Question 11
Must every sentence with 겠 describe a future intention?
- No, it also appears in conjecture and conventional expressions.
- Yes, intention is its only function.
Check the answer
Answer: No, it also appears in conjecture and conventional expressions.
No, it also appears in conjecture and conventional expressions.: The predicate and context determine its use.
Yes, intention is its only function.: This ignores other established uses.
Question 12
In 제가 하겠습니다, who offers to act?
- The food being described
- The speaker
Check the answer
Answer: The speaker
The food being described: That participant belongs to a different example.
The speaker: 제가 identifies the speaker as the actor.
Question 13
Does the conditional model guarantee free time?
- No, free time is the condition.
- Yes, the conditional asserts it already exists.
Check the answer
Answer: No, free time is the condition.
No, free time is the condition.: 으면 introduces the condition rather than asserting its truth.
Yes, the conditional asserts it already exists.: This would remove the uncertainty expressed by the sentence.
Question 14
What should a good self check preserve in a purpose sentence?
- An assumption that every goal was completed
- The difference between the asserted preparation and the intended goal
Check the answer
Answer: The difference between the asserted preparation and the intended goal
An assumption that every goal was completed: Purpose alone does not establish success.
The difference between the asserted preparation and the intended goal: Only the final action is explicitly asserted in the basic model.
