Korean Willpower & Guesses: Future Tense (`겠`)
겠 to express your firm willpower or to make polite, empathetic guesses about someone else's situation.
Grammar Rule in 30 Seconds
Use -겠- to express your strong intention or a logical guess about the future.
- Use for personal intention: 'I will do it' (e.g., 먹겠어요 - I will eat).
- Use for logical guessing: 'It must be' (e.g., 춥겠어요 - It must be cold).
- Attach directly to the verb stem: Stem + 겠 + Ending.
Overview
겠 is a crucial pre-final ending (선어말 어미) in Korean that functions as a modal auxiliary, expressing either the speaker's strong intention or will (의지, euiji) or the speaker's assumption or conjecture (추측, chuchuk). Unlike the more neutral future marker -(으)ㄹ 거예요, 겠 injects a degree of subjectivity, commitment, or inference into the statement. It reflects the speaker's internal state regarding a future action or a present/future state.
Understanding 겠 allows for more nuanced and natural communication, particularly in formal or empathetic contexts, moving beyond simple factual predictions to express personal conviction or reasoned deduction.
겠 is known for its grammatical simplicity, as it attaches directly to verb and adjective stems without regard for batchim (final consonants) or irregular verb rules. This consistency makes its formation straightforward once its dual meanings are grasped. Its usage often highlights politeness, determination, or a well-informed guess, making it indispensable for learners seeking to express more than basic future tense concepts.

How This Grammar Works
겠 functions as a modal pre-final ending, placed directly after a verb or adjective stem and before the final politeness or sentence-ending suffix. Its primary role is to convey the speaker's subjective assessment rather than an objective fact. This makes 겠 a powerful tool for expressing nuance in Korean, transcending a simple future tense marker.겠's function:- 1Intention/Volition (의지): When used with a first-person subject (나, 저, 우리 — ‘I’, ‘we’),
겠expresses the speaker's strong will, determination, or a firm promise. It often implies a sense of personal responsibility or a polite offer to undertake an action. For instance, in제가 연락드리겠습니다(I will contact you), the speaker is not just stating a future action but is committing to it with clear intent. This usage is common in formal settings, customer service, or when making a significant declaration. It contrasts with-(으)ㄹ 거예요, which indicates a general plan without the same degree of personal resolve. A waiter saying도와드리겠습니다(I will help you) uses겠to politely offer assistance, signifying their role and willingness to serve.
- 1Assumption/Conjecture (추측): When used with second-person, third-person, or general subjects,
겠expresses the speaker's strong but subjective assumption or logical deduction based on observable evidence or general knowledge. The speaker is making an educated guess about a situation, feeling, or future event. For example, seeing someone wearing a thick coat in summer might lead you to say춥겠어요(It must be cold). Here,겠indicates an inference. This form allows the speaker to empathize or comment on a situation without stating it as an absolute fact, as in힘들겠네요(That must be difficult), conveying understanding and concern. This usage is pervasive in daily conversation for reacting to others' circumstances or making observations about the environment.
Formation Pattern
겠 is notably straightforward due to its consistent attachment rules. Korean batchim (final consonant) rules and irregular verb conjugations, which often complicate other grammar points, do not apply to 겠. This simplicity makes 겠 one of the easiest pre-final endings to master in terms of mechanical application. The process involves three simple steps:
다 (da). This remaining part is the stem.
읽다 (ikt-da, to read) → 읽 (ik)
크다 (k'ŭ-da, to be big) → 크 (k'ŭ)
돕다 (dop-da, to help, a ㅂ irregular) → 돕 (dop) initially, but as 겠 doesn't trigger irregularity, it remains 돕 for attachment.
겠 Directly: Once you have the stem, simply attach 겠 (get) to its end. This step is uniform for all stems, irrespective of their final letter.
읽 + 겠 = 읽겠 (ik-get)
크 + 겠 = 크겠 (k'ŭ-get)
돕 + 겠 = 돕겠 (dop-get)
-(어/아)요 (which becomes 겠어요) and the formal -(읍/습)니다 (which becomes 겠습니다).
읽겠어요, 크겠어요, 돕겠어요
읽겠습니다, 크겠습니다, 돕겠습니다
ㄹ irregulars and ㅎ irregulars, which maintain their base stem form before 겠, simplifying conjugation significantly. For instance, 만들다 (man-dŭl-da, to make) becomes 만들겠어요 (man-dŭl-gesseoyo), and 빨갛다 (ppal-gat-ta, to be red) becomes 빨갛겠어요 (ppal-gat-gesseoyo).
When To Use It
겠 is employed in specific contexts that highlight the speaker's volition or their perceptive judgment. Its appropriate use adds significant naturalness to Korean communication.- 1Expressing Strong First-Person Intention/Will (의지):
최선을 다하겠습니다.(Ch'oesŏnŭl ta hagesseumnida. - I will do my best.) - A strong promise, typically in a formal setting like a job interview.제가 해보겠습니다.(Chega haebogessemnida. - I will try it myself.) - A clear declaration of intent to attempt something.제가 직접 찾아뵙겠습니다.(Chega chikchŏp ch'ajabyŏpkkesseumnida. - I will personally come and see you.) - A polite but firm commitment to meet someone, often in business.
- 1Making Polite Offers or Requests (First-person):
겠 softens offers and inquiries, showing deference and willingness to assist or understand the other person's wishes.무엇을 도와드릴까요?(Muŏsŭl towadŭrilkkayo? - What can I help you with?) - Often answered with도와드리겠습니다.(Towadŭrigesseumnida. - I will help you.).주문하시겠습니까?(Chumunhasigesseumnikka? - Would you like to order?) - A polite way for staff to ask a customer's intention.앉으시겠어요?(Anjŭsigesseoyo? - Would you like to sit?) - A polite invitation or offer.
- 1Expressing Assumption/Conjecture Based on Observation (추측):
