When attached to the te-form of a verb, ～ていく (te iku) indicates an action or state that is continuing and moving away from the speaker, both literally and figuratively.
For example, it can describe physical movement, like 歩いていく (aruite iku), meaning "to walk away."
It also expresses a gradual change or development into the future, such as 変わっていく (kawatte iku), meaning "to change (over time)."
This expression emphasizes the ongoing nature of the action or change as it progresses forward.
When used with a verb in its て-form, ～ていく indicates a change that progresses or moves forward in time or space, away from the speaker's current position or state. It suggests a continuation of an action or a process into the future or to a more distant location. Think of it as 'to go on doing something' or 'to continue to become something.'
For example, if you say 暖かくなっていく (atatakaku natte iku), it means 'it's getting warmer (and will continue to get warmer).' It can also describe a spatial movement away, like 歩いていく (aruite iku), meaning 'to walk away.' The nuance is about the ongoing nature of the change or movement.
§ Understanding 〜ていく
The Japanese auxiliary verb 〜ていく (te iku) is very common and useful. It indicates an action or a state that is continuing and moving forward, or changing away from the speaker. Think of it as 'going on' or 'going off into the future'. It's always attached to the 連用形 (ren'yōkei) or 'continuative form' of a verb, which is often the 〜て (te) form of the verb.
- Definition
- Auxiliary verb indicating a change continuing away from the speaker.
§ Basic Usage: Verb + ていく
The most common way to use 〜ていく is by simply attaching it to the 〜て form of a verb. This creates a compound verb that describes an action that starts now and continues into the future, or an action that moves away from the speaker's current location or perspective.
- Continuous Action: The action begins now and will continue.
- Movement Away: The action involves moving physically or figuratively away from the speaker.
日本語を勉強していくつもりです。
- Hint
- I plan to continue studying Japanese (from now on).
彼は家を出ていきました。
- Hint
- He left the house (and is now gone from here).
§ Expressing Gradual Change
〜ていく is also used to describe a gradual change or development over time. It suggests a process that is ongoing and progressing into the future.
だんだん暖かくなっていくでしょう。
- Hint
- It will gradually get warmer (as time goes on).
子供たちは成長していくものです。
- Hint
- Children are things that grow up (as time progresses).
§ Comparing with 〜てくる (te kuru)
It's helpful to compare 〜ていく with its counterpart 〜てくる (te kuru). While 〜ていく indicates movement or change *away* from the speaker's current point or into the future, 〜てくる indicates movement or change *towards* the speaker's current point or from the past up to now.
- 〜ていく: Action/state moves away or into the future.
- 〜てくる: Action/state moves towards or from the past up to now.
これからもっと忙しくなっていくでしょう。
- Hint
- It will probably get busier (from now on into the future).
今までずっと日本語を勉強してきました。
- Hint
- I have been studying Japanese (from the past up until now).
§ Common Verbs with 〜ていく
You'll often hear 〜ていく combined with verbs related to movement, change, or growth:
- なっていく (natte iku): to become (and continue to be)
- 増えていく (fuete iku): to increase (and continue to increase)
- 減っていく (hette iku): to decrease (and continue to decrease)
- 続けていく (tsuzukete iku): to continue (doing something)
- 生きていく (ikite iku): to live on, to go on living
Mastering 〜ていく will significantly improve your ability to express ongoing actions, changes, and future plans in Japanese. Pay attention to the context to understand the exact nuance of movement away or continuous change.
How Formal Is It?
"今後、社会は大きく変化していくでしょう。"
"この道はまっすぐ進んでいくと、駅に着きます。"
"あの雲はだんだん消えていったね。"
"赤ちゃんが毎日大きくなっていくね！"
"まぁ、なんとかやっていくさ。"
