Definition: “To Know” in Korean
The primary Korean verb for “to know” is 알다 (alda). It signifies being aware of a fact, possessing information, or having familiarity with a person, place, or thing. However, like many Korean verbs, 알다 (alda) transforms based on the formality of the situation and the relationship between the speaker and the listener. Understanding these transformations is essential for proper communication. Beyond the basic verb, other related verbs and expressions convey different aspects of knowledge, such as understanding, realizing, or being familiar with something. Furthermore, the negation of “to know” also has its nuances, requiring careful attention to detail.
Classification: Descriptive verb (동사)
Function: To express knowledge, awareness, or familiarity.
Contexts: Used in various contexts, including stating facts, expressing understanding, asking about someone’s knowledge, and describing familiarity with people or things.
Structural Breakdown
The basic structure for using 알다 (alda) in a sentence is similar to other Korean verbs. The subject is marked with a subject particle (은/는 or 이/가), the object (if any) is marked with an object particle (을/를), and the verb 알다 (alda) is placed at the end of the sentence.
The verb then conjugates depending on the tense, politeness level, and sentence type (declarative, interrogative, imperative, etc.).
The core verb stem is 알- (al-). To this stem, various endings are added to indicate tense, politeness, and mood. Here are some examples:
- 알아요 (arayo): I know (polite, present tense)
- 알았습니다 (aratseumnida): I knew/I have known (formal, past tense)
- 알 것이다 (al geotida): I will know (formal, future tense)
- 알 텐데 (al tende): I should know/I probably know (implying a condition or expectation)
The choice of ending depends heavily on the social context and the relationship between the speaker and the listener. Using the wrong ending can be considered impolite or awkward.

Usage Rules
Understanding the usage rules for expressing “to know” in Korean is essential for effective communication. These rules govern the proper use of different verb forms based on formality, politeness, and social context.
Failing to adhere to these rules can lead to misunderstandings or even offense.
Formal Usage
The formal usage of “to know” is typically employed in professional settings, presentations, and when addressing individuals of higher status or unfamiliar acquaintances. The verb form 압니다 (amnida) is the most common formal conjugation in the present tense. Past tense is expressed as 알았습니다 (aratseumnida), and future tense as 알 것입니다 (al geosimnida). These forms convey respect and professionalism.
Informal Usage
The informal usage of “to know” is reserved for close friends, family members, and individuals of equal or lower status in casual settings. The most common informal conjugation is 알아 (ara) in the present tense, 알았어 (arasseo) in the past tense, and 알 거야 (al geoya) in the future tense. Using these forms in formal situations can be perceived as disrespectful.
Honorific Usage
Honorific usage is employed to show respect to individuals of higher status, such as elders, teachers, or superiors. The honorific form of “to know” is 아십니다 (asimnida), derived from the verb stem 아시- (asi-). This form is used in formal settings and demonstrates deference. The past tense is 아셨습니다 (asyeotseumnida). Using non-honorific forms when addressing someone deserving of respect can be considered impolite.
