Overview
The expression 아/어 나가다 is an auxiliary verb construction that indicates an action or state has begun and is continuing, often with a sense of progression or development. It emphasizes the forward momentum of an action from a starting point, implying that the action is moving towards a future state or goal.
Usage
아/어 나가다 is attached to action verbs to describe an activity that is currently in progress and expected to continue or develop over time. It highlights the ongoing nature and forward trajectory of an action. This expression is frequently used when discussing long-term projects, personal growth, or any process that unfolds gradually. It can apply to both physical movements (e.g., 걸어 나가다 - to keep walking) and abstract processes (e.g., 공부해 나가다 - to continue studying). The core nuance is that the action is not just happening, but is actively moving forward or developing.
Conjugation Rules
The conjugation follows the standard 아/어/여 rules for connecting to the auxiliary verb 나가다:
- If the verb stem's last vowel is ㅏ or ㅗ, attach -아 나가다.
- Example: 살다 (to live) → 살아 나가다
- Example: 찾아 (to find) → 찾아 나가다
- If the verb stem's last vowel is anything other than ㅏ or ㅗ, or if it ends in a consonant, attach -어 나가다.
- Example: 만들다 (to make) → 만들어 나가다
- Example: 먹다 (to eat) → 먹어 나가다

Knowledge Plus
- Contrast with 아/어 오다: While 아/어 나가다 signifies an action continuing from a point into the future or from the present forward, 아/어 오다 indicates an action that has been continuing from the past up to the present moment.
- Example: 앞으로 계속 공부해 나갈 거예요. (I will continue studying from now on.)
- Example: 어릴 때부터 피아노를 쳐 왔어요. (I have been playing piano since I was young.)
- Contrast with 고 있다: 고 있다 simply describes an action that is currently in progress at a specific point in time. 아/어 나가다, however, emphasizes the duration, progression, and forward movement of an action over a period, often with an implied sense of development or moving towards a goal.
- Example: 지금 밥을 먹고 있어요. (I am eating rice right now.)
- Example: 이 프로젝트를 계속 진행해 나가야 해요. (We need to continue moving forward with this project.)
- This expression is particularly useful for describing processes, efforts, or journeys that require sustained action and show development over time.
