Transitive / Intransitive Lesson 8
Mastering the distinction between state-of-being (ている) and state-of-result (てある) using transitive and intransitive verb pairs.
Setting the Scene
Imagine you walk into a meeting room. You see a window that is open. You might say 'The window is open' (describing the state). Later, you notice someone has opened it on purpose to let air in. In Japanese, these two scenarios—a state resulting from an action vs. a state that just exists—use different grammatical structures.
The Core Mechanics
We use these patterns to describe the state of objects. The choice depends on whether we view the state as a natural occurrence or the result of a deliberate human action.
Tip
Seeing it in Action
Compare these examples to see how the focus shifts between the object's state and the agent's action.
窓が開いています。
The window is open.
窓が開けてあります。
The window has been opened (by someone).
机の上に書類が置いて【ある】。
Hint: Since 'placing' is a transitive action, what do we use for the resulting state?
Documents have been placed on the desk.
Nuance and Usage
Choosing between these is about whether you care about the 'who' or the 'what'.
Focus Comparison
〜ている
Focus on the current state of the object.
電気がついている (The light is on).
〜てある
Focus on the fact that someone did this for a reason.
電気がつけてある (The light has been turned on [for us/a purpose]).
Which sentence implies that someone purposely prepared the dinner?
- 夕食ができています。
- ✓ 夕食が作ってあります。
作ってあります uses the transitive verb '作ります' (to make), implying someone made it and left it ready.

When to avoid てある
Lesson Recap
In summary, use intransitive + ている for natural states and transitive + てある for states resulting from deliberate human actions. Mastering this distinction will make your Japanese sound much more precise and native-like.
