The Rule
가다 (gada) is one of the most essential Korean verbs, meaning "to go." It is a regular verb whose stem ends in the vowel ㅏ (a). To conjugate 가다, you first remove the dictionary ending 다 to get the stem 가. Then you apply the appropriate ending based on tense, politeness level, and sentence type. Because the stem vowel is ㅏ, it pairs with 아-type endings. Korean conjugation revolves around two key factors: whether the stem's last vowel is a bright vowel (ㅏ or ㅗ) or a dark vowel (everything else), and whether the stem ends in a consonant or vowel. Since 가 ends in a vowel and contains a bright vowel, it follows the simplest regular pattern. Mastering 가다 gives you a reliable template that works for hundreds of other regular verbs. Think of it as your conjugation home base. Every time you encounter a new regular verb, you can mentally compare it to 가다 and apply the same logic. This single verb unlocks a massive portion of Korean grammar.
Why English Speakers Struggle
English verb conjugation is minimal. You say "I go, he goes, I went" and that covers most situations. Korean, however, changes verb endings based on politeness level, tense, mood, and the verb stem's phonetic properties. English speakers often try to memorize each conjugated form as a separate vocabulary word rather than learning the underlying pattern. This leads to slow recall and frequent mistakes. Another common issue is the concept of vowel harmony. English has nothing like it. In Korean, if the stem's last vowel is ㅏ or ㅗ (bright vowels), you use 아-series endings. For all other vowels (dark vowels), you use 어-series endings. With 가다, since the stem vowel is ㅏ, the polite ending would theoretically be 가 + 아요. But here is where contraction enters the picture: 가 + 아요 contracts to 가요. English speakers sometimes write out both vowels, producing the incorrect 가아요. Understanding that Korean naturally contracts repeated or similar vowels is crucial for sounding natural.
Present Tense Conjugation
The present tense in Korean expresses actions happening now or habitual actions, similar to both "I go" and "I am going" in English. For the polite present tense (해요체, haeyoche), take the stem 가 and add 아요. Since the stem already ends in ㅏ, the two ㅏ sounds merge: 가 + 아요 = 가요 (gayo). This contraction is automatic and mandatory. You will never see 가아요 in correct Korean. For the formal present tense (합쇼체, hapshoche), add ㅂ니다 directly to the stem. Since 가 ends in a vowel, you attach ㅂ to the stem syllable: 갑니다 (gamnida). This form is used in news broadcasts, business presentations, military speech, and when addressing large groups. For casual speech among close friends, the ending is simply 가 (ga), dropping the 요. Understanding when to use each level is as important as knowing how to form it. Using casual speech with a stranger or elder is a serious social mistake in Korean culture.
Past Tense Conjugation
To form the past tense, Korean inserts the past tense marker 았/었 between the stem and the ending. For 가다, since the stem vowel is ㅏ (bright vowel), you use 았. The stem 가 combines with 았 to form 갔 (gat), using the double consonant ㅆ. Then add 어요 for polite speech: 갔어요 (gasseoyo), meaning "went." The formal past tense is 갔습니다 (gasseumnida). Notice how the ㅆ appears as a batchim (final consonant) on the 가 syllable. This is a common pattern: the past tense marker merges with the stem syllable when the stem ends in a vowel. For casual past tense, simply say 갔어 (gasseo). Understanding the past tense pattern is critical because Koreans use it constantly in daily conversation. "Where did you go?" (어디 갔어요?), "I went to school" (학교에 갔어요), and "They already went" (벌써 갔어요) are among the most frequently spoken sentences in Korean. Practice these until they become automatic.
Future Tense and Intention
Korean has multiple ways to express future actions and intentions. The most common construction is stem + ㄹ/을 거예요. For 가다, since the stem 가 ends in a vowel, attach ㄹ directly: 갈 거예요 (gal geoyeyo), meaning "will go" or "am going to go." The formal version is 갈 것입니다 (gal geosimnida). Another way to express intention is the ㄹ게요 ending: 갈게요 (galgeyo), which means "I will go" with a nuance of making a decision or promise in the moment. This is different from 갈 거예요, which is more of a neutral statement about future plans. A third option is 가겠어요 (gagesseoyo), which expresses strong intention or conjecture: "I shall go" or "I suppose someone goes." Each future form carries a different nuance. Beginners should start with ㄹ 거예요 as it covers most situations. As you progress, add ㄹ게요 for first-person promises and 겠 for formal announcements or conjecture about others' actions.
Negative Forms
Korean has two main ways to negate verbs. The short negation places 안 (an) before the verb: 안 가요 (an gayo) means "don't go" or "am not going." This is the most common negation in spoken Korean because it is quick and natural. The long negation uses the pattern verb stem + 지 않다: 가지 않아요 (gaji anayo). This form is slightly more formal and emphatic. Both mean the same thing, but the long form is preferred in writing and formal speech. For the past negative: 안 갔어요 (an gasseoyo) or 가지 않았어요 (gaji anasseoyo), meaning "did not go." For future negative: 안 갈 거예요 (an gal geoyeyo). There is also the "cannot" form using 못 (mot): 못 가요 (mot gayo) means "cannot go," implying inability rather than choice. The long form equivalent is 가지 못해요 (gaji motaeyo). Distinguishing between 안 (choosing not to) and 못 (unable to) is important for clear communication. Saying 안 갔어요 means you chose not to go, while 못 갔어요 means something prevented you.
Connecting and Modifier Forms
Beyond simple tenses, verbs in Korean frequently appear in connecting forms that link clauses together. The most common connector is 고 (go): 가고 (gago) means "go and..." as in 학교에 가고 공부해요 (I go to school and study). The reason connector 아서/어서 becomes 가서 (gaseo): "because/after going." For example, 시장에 가서 사과를 샀어요 (I went to the market and bought apples). The conditional form uses 면: 가면 (gamyeon) means "if (someone) goes." The modifier form for describing nouns uses ㄴ/는/ㄹ: 가는 (ganeun) means "going" as an adjective (가는 길, the road one is going on), 간 (gan) means "went" as modifier (간 사람, the person who went), and 갈 (gal) means "will go" (갈 곳, a place to go). These modifier forms are essential for building complex Korean sentences. Practice them in context rather than isolation. Try describing your daily routine using connecting forms: 아침에 일어나서 학교에 가고 공부해요 (I wake up in the morning, go to school, and study).
Imperative and Propositive Forms
The imperative (command) form of 가다 varies by politeness level. Polite imperative: 가세요 (gaseyo) means "please go." This is the standard way to tell someone to go without being rude. Formal imperative: 가십시오 (gasipsio) is very formal, used in announcements or military contexts. Casual imperative: 가 (ga) is used among close friends or to children. The propositive ("let's") form also varies: 가요 (gayo) can actually serve double duty as both "I go" and "let's go" depending on context and intonation. The explicit propositive is 갑시다 (gapsida) for formal situations or 가자 (gaja) for casual speech. There is also the softened suggestion 갈까요? (galkkayo?) meaning "shall we go?" which is polite and commonly used when making plans. Notice that Korean packs enormous social meaning into verb endings. The difference between 가 (casual command), 가세요 (polite request), and 가십시오 (formal order) reflects the speaker's relationship to the listener. Using the wrong level is not just a grammar mistake — it can cause genuine offense.
Practice Strategy
Start by mastering the 해요체 (polite) form 가요 since you will use it in roughly 90 percent of daily conversations. Once that feels natural, add the past tense 갔어요 and the future 갈 거예요. These three forms — present, past, future in polite speech — cover most communication needs. Next, learn the formal equivalents: 갑니다, 갔습니다, 갈 것입니다 for workplace and formal situations. Then practice negative forms: 안 가요 and 못 가요. A powerful exercise is to narrate your day using only 가다 conjugations: 아침에 학교에 가요 (I go to school in the morning), 어제 서울에 갔어요 (I went to Seoul yesterday), 내일 부산에 갈 거예요 (I will go to Busan tomorrow). Since 가다 is regular, every pattern you learn here transfers directly to other regular verbs. Use 가다 as your mental benchmark. When you encounter 오다 (to come), 보다 (to see), or 사다 (to buy), just swap the stem and apply the same endings.

Common Mistakes
Incorrect: 가아요 → Correct: 가요. ㅏ + 아요 contracts to 가요. Never write both vowels separately.
Incorrect: 가았어요 → Correct: 갔어요. Past tense marker 았 merges into the stem syllable: 가 + 았 = 갔.
Incorrect: 갈거예요 → Correct: 갈 거예요. There must be a space between 갈 and 거예요. It is two separate words.
Incorrect: 가겠어요 (for simple future) → Correct: 갈 거예요. 겠 implies strong will or conjecture. For neutral future plans, use ㄹ 거예요.
Incorrect: 안 갈 거예요 (meaning 'cannot') → Correct: 못 갈 거예요. 안 means choosing not to; 못 means unable to. Use 못 for inability.
