Everyday polite Korean verbs

01 / Understand

Start from the dictionary form, then find the stem

Korean dictionaries normally list verbs and descriptive predicates with 다 at the end. To build the everyday polite forms in this lesson, first remove that dictionary ending and identify the stem. 먹다, to eat, gives 먹. 가다, to go, gives 가. The polite ending then attaches to that stem. Do not keep 다 and simply add 요 after the complete dictionary entry; 먹다요 is not the ordinary form meaning I eat.

The polite ending does not change for I, you, or they in the way many European verb endings do. 먹어요 can be understood as eat or eats, or am eating in the right context. Who acts and when must come from the sentence and situation. This lesson focuses on ordinary present descriptions and habits. It does not claim that one form captures every English tense or that politeness is determined only by the final syllable.

Use the last stem vowel as the regular starting rule

For a regular stem, the last vowel helps choose 아요 or 어요. A stem whose last vowel is ㅏ or ㅗ generally takes 아요. Other vowels generally lead to 어요. In 살다, to live, the stem 살 contains ㅏ, so the result is 살아요. In 먹다, the vowel is ㅓ, so the result is 먹어요. Look at the last vowel in the stem, not the final 다 of the dictionary form.

When the stem ends with a consonant, the vowel ending usually appears as an additional written syllable. The final consonant can link to that vowel in pronunciation, while the spelling keeps the stem recognizable. The rule is a starting pattern, not permission to ignore contractions or irregular stems. Learn a new verb with one useful polite form beside its dictionary entry so that a future exception is recorded as part of the word rather than discovered repeatedly by guessing.

03 / Understand

Let adjacent vowels contract where the pattern allows

When a stem already ends in a vowel, adding another vowel can produce a contraction. 가 plus 아요 gives 가요; the same a vowel is not normally repeated in separate syllables. 오 plus 아요 commonly becomes 와요, and 보 plus 아요 commonly becomes 봐요. These spellings use compound vowel shapes you met in the Hangul lesson. A contraction changes the written combination without creating a new verb meaning.

Other common combinations include 배우다 becoming 배워요 and 마시다 becoming 마셔요. The last vowel and the following ending combine, so a spelling built by mechanically appending 어요 can sound less natural or miss the common contracted form. Not every possible contraction behaves identically, and some fuller variants exist. The exercises request the ordinary forms taught here. Read each complete form with a recording rather than treating the Roman transcription as a precise guide to every sound change.

04 / Understand

Learn 해요 as the common form of 하다

하다 is extremely common, both on its own and in longer verbs. Its everyday polite form is 해요. Thus 공부하다 becomes 공부해요, to study, and 연습하다 becomes 연습해요, to practice. Learn this frequent pattern directly instead of trying to force 하 into the ordinary 아요 rule. The longer form 하여요 is related historically and structurally, but 해요 is the useful everyday target in these examples.

Many noun plus 하다 combinations let you recognize the activity inside the verb: 공부 concerns study and 연습 concerns practice. However, removing 하다 does not guarantee that every resulting string is a free standing noun with exactly the English meaning you expect. Check the dictionary entry when meeting a new word. For production, choose one familiar activity and say when or what you practice. This makes the ending serve a message rather than remaining an isolated conjugation drill.

05 / Understand

Expect some stems to change before the ending

Some verbs change their stem before a vowel ending. 듣다, to hear or listen, becomes 들어요. 걷다, meaning to walk, becomes 걸어요. In these verbs, final ㄷ changes to ㄹ before the vowel ending. But 받다, to receive, keeps ㄷ and becomes 받아요. A final letter alone cannot tell you whether a verb belongs to the irregular pattern. Record the meaning and the actual inflected form together.

Other changes affect different final letters and vowels. For example, a descriptive predicate such as 쉽다, to be easy, becomes 쉬워요. You do not need to master every irregular family to begin speaking, but you should know when the regular rule has reached its limit. If your predicted form differs from a reliable dictionary model, compare the stem and ending rather than assuming the reference is a random exception. Later practice can group words that genuinely share the same change.

06 / Understand

Build the message around the final predicate

A basic Korean sentence places its predicate at the end. 저는 한국어를 공부해요 means I study Korean. The topic 저는 establishes the speaker, 한국어를 marks what is studied, and 공부해요 finishes the statement. If the person is clear, the topic can be omitted. The object can also be omitted when it is understood, but an explicit full example is useful while learning which part contributes which meaning.

Descriptive predicates use polite forms too. 좋아요 can mean is good, without adding a separate noun identification ending. This differs from 학생이에요, is a student, which identifies someone with a noun. A descriptive form before a noun is another construction again, such as 좋은 책, a good book. For now, keep the full sentence ending distinct from the form that modifies a following noun. Mixing those jobs often produces an unnecessary extra ending.

07 / Understand

Ask and negate without rebuilding the word order

The same everyday polite ending can appear in a question: 커피를 마셔요? asks whether the listener drinks coffee in the relevant context. Question intonation and the situation distinguish it from a statement. A question word can supply a more specific request, as in 뭐 마셔요, what are you drinking. You do not add an English style do or does before the Korean sentence.

For a simple negative, 안 often appears before the predicate: 안 가요 means do not go or am not going in a statement about the understood subject. This is not automatically an instruction forbidding someone to go. Another useful pattern attaches 지 to the stem and follows it with 않아요: 가지 않아요. With an activity verb like 공부하다, 공부 안 해요 is common, and 공부하지 않아요 is another clear option. Noun identities use 아니에요 instead, so keep that negative pattern separate.

Move from a conjugation to a useful exchange

Use a short decision path for a new familiar verb. Find its dictionary form and remove 다. Check whether you already know an irregular polite form. If it is regular, inspect the last stem vowel, add the appropriate ending, and apply the common contraction. Then put that form at the end of a sentence with a meaningful person, object, or time phrase. A correct ending is most useful when it helps someone understand what you do.

After reading the examples, cover the polite forms and retrieve them from the dictionary forms. Explain the reason for one regular answer and one irregular answer. Next say a positive sentence, turn it into a question, and give a negative reply. The games below check written decisions; they do not measure pronunciation or certify conversational fluency. Keep a small set of accurate phrases in circulation and return later, increasing variety only when you can reconstruct them without copying.
