The Rule
마시다 (masida) means "drink" and is a regular Korean verb. To conjugate it, remove 다 from the dictionary form to get the stem 마시. The stem's last vowel is a dark vowel, so it pairs with 어-type endings. In Korean, ㅣ + 어 contracts to ㅕ, so 마시 + 어요 becomes 마셔요. This is a regular contraction rule for stems ending in ㅣ. Regular verbs like 마시다 follow predictable patterns, which means once you learn how to conjugate this verb, you can apply the same rules to many other verbs that share similar stem characteristics. The key to Korean conjugation is a two-step analysis: first determine whether the stem's last vowel is bright (ㅏ or ㅗ) or dark (all others), then check whether the stem ends in a vowel or consonant. This determines which set of endings to use and whether contraction or buffer vowels are needed. 마시다 is an excellent verb to practice because it appears frequently in everyday Korean conversation.
Why English Speakers Struggle
English speakers learning Korean often find verb conjugation overwhelming because English barely changes verb forms. In Korean, every verb ending carries information about tense, politeness, mood, and sometimes the speaker's relationship to the listener. With 마시다, the main challenge is remembering the correct ending for each situation. The contraction of ㅣ + 어 → ㅕ trips up many learners. You might want to say 마시어요, but the natural Korean form is 마셔요. This contraction is consistent across all ㅣ-ending stems. Another common difficulty is the concept of speech levels. Korean has at least six distinct politeness levels, though most learners focus on two: 해요체 (polite informal) and 합쇼체 (formal). Using the wrong level can sound disrespectful or awkwardly formal. English has nothing comparable — you would not change the verb form when speaking to your boss versus your friend. Understanding that Korean verb endings are social signals, not just grammar, helps learners appreciate why accuracy matters. Practice 마시다 in both polite and formal registers until switching between them feels natural.
Present Tense Conjugation
The polite present tense (해요체) of 마시다 is 마셔요 (masyeoyo). To form this, take the stem 마시 and add 어요. Since the stem ends in a vowel, contraction may occur depending on the specific vowels involved. The formal present tense (합쇼체) is 마십니다 (masimnida). For vowel-ending stems, attach ㅂ니다 by adding ㅂ as a batchim to the stem syllable. The casual present drops 요: just use the stem plus 어. In daily conversation, the polite present covers both ongoing actions and habitual ones. Context and time expressions clarify which meaning is intended. For example, adding 지금 (now) indicates current action, while 매일 (every day) indicates habit. Practice saying sentences with time markers to build natural Korean rhythm.
Past Tense Conjugation
The polite past tense of 마시다 is 마셨어요 (masyeosseoyo). The past tense marker is 었 for dark-vowel stems. When the stem ends in a vowel, the past marker merges with it. The formal past tense adds 습니다 to the past stem. Korean past tense works somewhat differently from English. It can express completed actions (I ate), experienced states (I was tired), and even discoveries (Oh, it was here!). The past tense in Korean is definitive — it states that something happened. For recent past actions, Koreans often add 방금 (just now) or 아까 (earlier). For distant past, 예전에 (long ago) or 어렸을 때 (when young) provide temporal context. Practice narrating past events using 마시다 to build fluency with past tense construction. Try describing what you did yesterday using multiple past tense sentences connected with 고 (and then).
Future Tense and Intention
The future tense of 마시다 uses ㄹ 거예요: 마실 거예요 (masil geoyeyo). Since the stem ends in a vowel, ㄹ attaches directly as a batchim. Korean has three main ways to express future meaning, each with different nuances. The ㄹ 거예요 form is the most neutral and common, expressing planned or predicted future actions. The ㄹ게요 form expresses a first-person decision or promise made in the moment. The 겠 form expresses strong intention or conjecture about others. For beginners, focus on ㄹ 거예요 as it covers most situations. When making plans with friends, use this form: 내일 뭐 할 거예요? (What will you do tomorrow?). When someone asks you to do something and you agree on the spot, switch to ㄹ게요 to show your immediate commitment. As you advance, the 겠 form will become important for formal speech and expressing guesses about others' actions.
Negative Forms
The short negation of 마시다 is 안 마셔요 (an masyeoyo), placing 안 before the verb. The long negation follows the pattern stem + 지 않다. Both mean the same thing, but the long form is slightly more emphatic and preferred in writing. For inability, use 못 before the verb. The distinction between 안 (choice) and 못 (inability) is important in Korean. Saying 안 했어요 means you chose not to do it, while 못 했어요 means circumstances prevented you. This distinction does not exist in simple English negation. Korean also has the negative command form: verb stem + 지 마세요 means "please don't." For example, adding 지 마세요 to the stem creates a polite prohibition. The casual negative command drops 세요, becoming 지 마. Practice all negative forms because they appear in conversation just as often as positive forms. Korean speakers frequently use double negatives for emphasis, which is grammatically correct in Korean unlike in English.
Cultural Context: Drinking in Korea
Korean drinking culture is significant, and 마시다 appears in many social expressions. 술을 마시다 (sureul masida) means to drink alcohol. The expression 한잔 하다 (hanjan hada, have a drink) is a casual invitation. When someone pours you a drink, it is polite to hold your glass with both hands. When drinking with elders, turn your head to the side. These cultural nuances accompany the verb 마시다 in real life. Coffee culture is also enormous in Korea — 커피 마실래요? (Would you like to drink coffee?) is one of the most common social invitations. The verb 마시다 is used exclusively for liquids. For medicine in pill form, Koreans use 먹다 (eat). Understanding these usage boundaries helps you sound natural. Practice ordering drinks at a cafe: 아메리카노 마실게요 (I will have an Americano), 물 좀 마실 수 있을까요? (Could I have some water?).
Connecting and Modifier Forms
Korean sentences often chain multiple clauses using connecting verb forms. The most common connector 고 attaches directly to the stem: 마시고 means "drink and." The sequential or causal connector 어서 creates a flow of events or cause-and-effect. The conditional 면 means "if." Modifier forms turn verbs into adjectives that describe nouns. The present modifier 는 attaches to the stem (with consonant adjustments as needed). The past modifier ㄴ/은 and future modifier ㄹ/을 follow the vowel or consonant stem rules. These modifier forms are essential for building complex, natural Korean sentences. Without them, you are limited to simple subject-verb-object patterns. Practice by creating noun phrases: the thing you drink, the person who drinks, the place where you will drink. These structures appear in nearly every Korean conversation.
Practice Strategy
Start with the three core polite forms: 마셔요 (present), 마셨어요 (past), 마실 거예요 (future). Practice by creating sentences about your daily life using 마시다. Once these feel natural, add the formal versions for workplace and official situations. Then master the negative forms: 안 마셔요 (don't) and 못 + verb (cannot). A useful exercise is to conjugate 마시다 through all forms in a single practice session: present, past, future, negative, conditional, connecting, and modifier forms. Write each form down, say it aloud, and create a sentence using it. Compare 마시다 with other verbs you have learned to reinforce the pattern. If the stem characteristics match (same vowel type, same ending type), the conjugation will be identical. This pattern recognition approach is far more efficient than memorizing each verb's conjugations individually.

Common Mistakes
Incorrect: 마시아요 → Correct: 마셔요. The stem vowel is dark, so use 어-type endings.
Incorrect: 마시어요 → Correct: 마셔요. ㅣ + 어 contracts to ㅕ. Never write both vowels separately.
Incorrect: 마십시오 (casual) → Correct: 마셔. 마십시오 is extremely formal. Use 마셔 for casual or 마셔요 for polite.
Incorrect: 마시ㅂ니다 → Correct: 마십니다. The ㅂ merges into the stem syllable as batchim: 마십니다.
Incorrect: 마시을 거예요 → Correct: 마실 거예요. Vowel-ending stems use ㄹ, not 을. 마시 + ㄹ = 마실.
