Overview
The ending -아/어/여 (often seen as -아요/어요/여요) is one of the most fundamental and frequently used sentence endings in Korean. It serves primarily to express the present tense in the informal-polite speech level (해체), making it suitable for everyday conversations with people you are somewhat familiar with, but still wish to show politeness.
Usage
This ending is highly versatile and is used to convey several nuances related to the present tense:
- Current Actions or States: Describes what is happening right now or a current condition.
- Example: 지금 밥을 먹어요. (I am eating rice now.)
- Habitual Actions or General Truths: Expresses actions that occur regularly or facts that are generally true.
- Example: 저는 매일 커피를 마셔요. (I drink coffee every day.)
- Informal-Polite Speech Level: It is the standard ending for the '해체' speech level, which is widely used in daily life. Depending on intonation, it can function as a declarative statement, an interrogative question, a propositive suggestion, or even an imperative command.
- Declarative: 날씨가 좋아요. (The weather is good.)
- Interrogative: 날씨가 좋아요? (Is the weather good?)
- Propositive: 같이 영화 봐요. (Let's watch a movie together.)
- Imperative: 여기 앉아요. (Sit here.)

Knowledge Plus
- The -아/어/여요 ending is the most common way to express politeness in everyday Korean. It is less formal than -ㅂ니다/습니다 but more polite than the plain form -ㄴ/는다.
- While the base form is -아/어/여, the -요 particle is almost always attached in spoken and written informal-polite contexts to convey politeness. Without -요, the form becomes the 해체 (haeche) or 반말 (banmal) form, which is used with close friends or those younger than you.
- This ending is foundational. Many other grammatical constructions and endings are built upon the -아/어/여 stem (e.g., -아/어서, -아/어야 하다, -아/어 보다).
