What Does ておく (te oku) Mean?
The structure ておく combines the te-form of a verb with the verb おく (oku), which means “to put” or “to place.” In this grammar pattern, おく loses its literal meaning and instead implies doing something in advance, or “to do and leave (as is)” for a later purpose. It’s similar to the English expressions “do something in preparation,” “get something ready,” or “do something beforehand.”
How to Form ておく
To use ておく, first conjugate the main verb into its te-form, then add おく. Here’s the simple formula:
Verb (te-form) + おく
Let’s look at a few examples:
- 食べる (taberu) → 食べておく (tabete oku) – to eat in advance
- 買う (kau) → 買っておく (katte oku) – to buy (something) beforehand
- 調べる (shiraberu) → 調べておく (shirabete oku) – to look up (information) in advance
Common Uses of ておく
1. Preparation for a Future Event
One of the main uses of ておく is to indicate that an action is done in preparation for something expected in the future. For example:
会議の前に資料をコピーしておきます。
(Kaigi no mae ni shiryō o kopī shite okimasu.)
I will copy the documents before the meeting (in preparation).
2. Leaving Something as Is
ておく can also mean to leave something in its current state for convenience or necessity:
このままにしておいてください。
(Kono mama ni shite oite kudasai.)
Please leave it as it is.
3. Preventive Actions
Sometimes, ておく is used for preventive actions to avoid problems:
雨が降りそうだから、窓を閉めておきました。
(Ame ga furi-sō dakara, mado o shimete okimashita.)
Since it looks like rain, I closed the windows in advance.
Variations and Politeness
Just like other Japanese verbs, ておく can be conjugated for tense and politeness:
- ておきます (te okimasu): Polite present/future
- ておきました (te okimashita): Polite past
- ておこう (te okou): Volitional (“Let’s do in advance”)
- ておいて (te oite): Te-form, often used in requests
Example:
パーティーの前に部屋を掃除しておきましょう。
(Pātī no mae ni heya o sōji shite okimashō.)
Let’s clean the room before the party (in preparation).
Difference Between ておく and Other Similar Expressions
It’s important not to confuse ておく with other te-form expressions like てみる (te miru, “try doing”) or てしまう (te shimau, “finish doing” or “regrettably do”). While ておく specifically focuses on doing something for a future benefit or preparation, the others have completely different nuances.
