아/어 있다

Overview

The grammatical pattern -아/어 있다 is used to express a continuing state that results from a completed action. It emphasizes the resultant state rather than the action itself. Unlike -고 있다 which describes an action currently in progress (e.g., 'eating'), -아/어 있다 describes the state that remains after an action has finished (e.g., 'is seated').

Usage

This pattern is primarily used with intransitive verbs that describe a change of position or state (e.g., 앉다 'to sit', 서다 'to stand', 눕다 'to lie down') or with passive verbs (e.g., 열리다 'to be opened', 닫히다 'to be closed', 놓이다 'to be placed'). It signifies that the subject is currently in the state brought about by the verb's action. The focus is on the result of an action, not the action itself. For instance, when you say 앉아 있다, it means 'is seated' or 'is sitting (in a seated position)', emphasizing the state of being seated, not the action of sitting down. While -고 있다 describes an ongoing action (e.g., '먹고 있다' - is eating), -아/어 있다 describes a state that has resulted from a completed action (e.g., '문이 열려 있다' - the door is open, having been opened).

Conjugation Rules

The -아/어 part follows the standard vowel harmony rules for Korean verbs.

• If the last vowel of the verb stem is ㅏ or ㅗ, attach -아 있다.
  • Example: 앉다 (to sit) -> 앉 + 아 있다 -> 앉아 있다 (is seated)
• If the last vowel of the verb stem is anything other than ㅏ or ㅗ, attach -어 있다.
  • Example: 서다 (to stand) -> 서 + 어 있다 -> 서 있다 (is standing)
  • Example: 눕다 (to lie down) -> 눕 + 어 있다 -> 누워 있다 (is lying down)
• For verb stems ending in 하다, change to -해 있다.
  • Example: 준비하다 (to prepare) -> 준비 + 해 있다 -> 준비해 있다 (is prepared)
• Verbs ending in -이다 (passive form) often combine to -여 있다.
  • Example: 놓이다 (to be placed) -> 놓 + 여 있다 -> 놓여 있다 (is placed)
  • Example: 열리다 (to be opened) -> 열리 + 어 있다 -> 열려 있다 (is open)

Knowledge Plus

It's crucial to distinguish -아/어 있다 from -고 있다. While -고 있다 indicates an action in progress (e.g., '먹고 있다' - is eating), -아/어 있다 indicates the state resulting from a completed action (e.g., '앉아 있다' - is seated). You generally cannot use -아/어 있다 with verbs that describe continuous actions like '먹다' (to eat) or '공부하다' (to study).

This pattern is very frequently used with passive verbs to describe the state of an object. For instance, '문이 열려 있다' (the door is open) uses the passive form '열리다' (to be opened) to describe the door's state after being opened.

Some common verbs that frequently appear with -아/어 있다 include: 앉다 (to sit), 서다 (to stand), 눕다 (to lie down), 놓이다 (to be placed), 걸리다 (to be hung), 열리다 (to be opened), 닫히다 (to be closed), 쌓이다 (to be piled up), 준비하다 (to prepare - often as '준비해 있다').
