～ている vs ～てある: State, Action, and the Implied Agent

The ～ている vs ～てある contrast involves two forms that can both describe a present state. ～てある adds an implied human agent who brought the state about on purpose and left the result in place.¹² Telling them apart is an N4 hurdle because the English translation hides the signal that decides the form.

Overview

The one-sentence contrast

Both forms can report how something is right now, so learners often mix them up. The difference is agency: ～てある says a person did the action deliberately and left the result, while plain ～ている makes no such claim.¹²

Japanese teaching materials draw the same line. A change-of-state intransitive verb with ～ている presents a state the thing arrived at on its own. By contrast, ～てある presents a state その状態が誰か人の行為によってもたらされた, "that state was brought about by the action of some person."²

てある is the "someone did it on purpose" form

～てある describes the current state of something while implying that someone acted on it earlier and left it that way. It is used with intentional verbs to describe a present state resulting from a past action done for a purpose.³

Why this pair is a known stumbling block

Both forms often collapse to the same English, such as "is open" or "is done," so the translation gives learners no signal for choosing the correct form.⁴

The deciding signal is verb transitivity, not the いる/ある swap by itself. ～ている attaches to both transitive and intransitive verbs, but ～てある attaches only to transitive verbs.¹³ You cannot freely change いる to ある; ～てある requires a transitive stem.

Prerequisite: transitivity is the lever

Intransitive (自動詞) vs transitive (他動詞) in one line

An intransitive verb (自動詞) describes a change or event the subject undergoes by itself. It marks that subject with が, as in ドアが開く ("the door opens"). A transitive verb (他動詞) describes an agent acting on an object. It marks that object with を, as in ドアを開ける ("[someone] opens the door").⁴

開く (intransitive) and 開ける (transitive) form a paired set, a 自他のペア. The form choice below depends on this transitivity contrast.²⁴

Which form each verb type takes

The verb's transitivity determines which options are available before nuance enters. An intransitive verb has only one path; a transitive verb forks into two.

• Intransitive verb + ～ている gives a plain resultant state: the thing is in the state, with no agent claimed.²
• Transitive verb + ～ている gives an ongoing action in progress (someone is doing it now).⁴
• Transitive verb + ～てある gives a resultant state explicitly brought about by an unstated agent on purpose.¹⁵

The TUFS module states the restriction on ～てある directly: the verb must take a を-object and change that object. It gives 開ける, 置く, 消す, and 切る as examples of qualifying verbs.⁵

～ている: activity and observed state

Intransitive verb + ている = plain resultant state

With a punctual, change-of-state intransitive verb, ～ている expresses the persisting result of a completed change. This is a resultant-state (結果の状態, the state left after a change) reading, not a progressive one.⁶

This follows from Kindaichi's 1950 verb classification. 瞬間動詞 (punctual verbs such as 死ぬ, 消える, 壊れる) in the ～ている form express that the action has ended and its result persists. 継続動詞 (continuous verbs such as 読む, 書く) in ～ている express an action in progress.⁶

The intransitive resultant-state ～ている makes no claim about who caused the state or why. が marks the thing that is in the state.²

窓まどが閉しまっている。²
"The window is closed."

電気でんきが消きえている。⁶
"The light is off."

Transitive verb + ている = ongoing action

With a transitive, continuous verb, ～ている is read as an action in progress, and を marks the object being acted on.⁴ This directly contrasts with the ～てある case below: same transitive stem, different auxiliary, different aspect.

彼かれがドアを開あけている。⁴
"He is opening the door."

私わたしは窓まどを閉しめている。⁴
"I am closing the window."

Pointer, not re-teach

～ている has more than one reading, including progressive and resultant-state readings. Kindaichi's 1950 verb classes help sort them, but the full inventory belongs in the dedicated ～ている article, not here. For this contrast, only the two readings above are needed.⁶

～てある: pre-arranged state with an implied agent

Form: transitive verb + てある

The formation is the transitive verb te-form plus ある. The auxiliary ある, the existence verb for inanimate things, carries the "the result exists" meaning.¹⁷

The object of the underlying transitive action moves into the subject slot and is typically marked が, as in ドアが開けてある, 窓が閉めてある, and 切符が買ってある.⁵² The verb is restricted to transitive verbs that take a を-object and change that object's state.⁵

窓まどが閉しめてあります。⁵
"The window has been closed (and left that way)."

問題もんだいは15ページに書かいてあります。⁵
"The problem is written on page 15."

The two nuances てある carries

First, a human agent deliberately did the action. ～てある describes a situation brought about on purpose by somebody who is left unnamed. The Japanese framing is 人が何か目的をもって、その行為をした, "a person performed the action with some purpose in mind."⁸²

Second, the action was done for a purpose or in advance, and the result is being kept in place. Genki notes that a ～てある state can be re-described as the result of a ～ておきました ("did in advance") action.⁸

Both nuances are absent from the intransitive ～ている, which asserts only the bare state.²

The が↔を shift

The same transitive stem appears with two different particles depending on the form, and the particle is the visible clue. を on the object points to the ongoing-action ～ている; が on the promoted object points to the resultant-state ～てある.

窓まどを閉しめている。⁴
"I am closing the window."

窓まどが閉しめてある。²
"The window has been closed (and left that way)."

～てある itself permits both が and を on the affected noun, with a nuance difference. が presents the resultant state neutrally: the noun is both the object of the verb and the subject of the state. を keeps focus on the intentional action carried out for a purpose. The TUFS module marks the standard resultant-state pattern as （Nは／が）Vてあります and treats the を variant as the preparation-flavored option.⁵

How to choose: the three-way contrast

開いている / 開けている / 開けてある side by side

One open door can be described three ways. The verb's transitivity and the auxiliary you choose decide which reading you get.

Form	Verb type	Particle	Aspect	Implied agent?	Gloss
ドアが開いている	intransitive 開く + ている	が	resultant state	no	"the door is open" (neutral)2
(誰かが)ドアを開けている	transitive 開ける + ている	を	ongoing action	yes (acting now)	"(someone) is opening the door"4
ドアが開けてある	transitive 開ける + てある	が	resultant state	yes (acted earlier, on purpose, left it)	"the door has been opened and left so on purpose"52

ドアが開あいている。²
"The door is open."

誰だれかがドアを開あけている。⁴
"Someone is opening the door."

ドアが開あけてある。⁵²
"The door has been opened (and left open on purpose)."

A decision procedure

You can make the choice with three checks: transitivity first, aspect second, and particle as confirmation.

• Step 1: Is the verb transitive (他動詞, takes を) or intransitive (自動詞, takes が)? If intransitive, only ～ている is available, and it gives a plain resultant state.¹⁵
• Step 2: If transitive, is the action ongoing right now (→ ～ている) or is it a kept result of an earlier intentional action (→ ～てある)?⁴
• Step 3: Confirm with the particle. を on the object points to transitive ～ている; が on the former object points to ～てある.⁵⁴

When both are grammatical, what changes

ドアが開いている and ドアが開けてある can both describe the same physically open door. The first reports the state neutrally. The second asserts that a person opened it on purpose and left it open, typically for a reason such as ventilation.⁹

The practical difference is agency and intention, not the physical facts. ～てある invites the inference "someone did this deliberately," which ～ている does not.²⁹

Nuance and usage contexts

てある for preparation and reassurance

～てある frequently signals that something has been taken care of in advance, which is why it pairs naturally with reassurance.⁸ The result of an earlier deliberate act is being kept available and ready.

切符きっぷはもう買かってある。⁸
"The tickets have already been bought (they're ready)."

予約よやくがしてあります。⁸
"The reservation has been made (it's taken care of)."

This "done in advance" sense is where ～てある shades toward ～おく, the form for doing something in advance or leaving a thing in a state. Genki notes that a ～てある state can be re-described as the result of a ～ておきました action.⁸¹⁰ The two forms are related but distinct: ～ておく names the act of preparing, while ～てある names the resulting state that preparation left behind.

Two related forms, one boundary

The advance-preparation form names the action of preparing; ～てある names the resulting state that preparation leaves in place. They overlap in meaning but answer different questions, so keep them apart even when both fit a situation.⁸¹⁰

Register and frequency

Both forms are everyday N4 grammar used in ordinary spoken and written Japanese.⁹ ～てある is the marked member of the pair: it adds the agent-and-intention layer that plain intransitive ～ている lacks. Use it only when that deliberate-arrangement meaning is intended.²³

Good to know

You cannot put an intransitive verb in ～てある

～てある requires a transitive stem that takes a を-object and changes it, so an intransitive verb like 開く cannot take ～てある. A learner who writes ドアが開いてある has tried to swap いる for ある on an intransitive verb, but this is not a free toggle. Use the intransitive state form instead, or switch to the transitive verb if you want the implied-agent meaning.⁵³

ドアが開あいている。²
"The door is open."

てある is not the passive

It is tempting to read ドアが開けてある as a passive, but ドアが開けられている is the actual passive. It means the door is or has been opened, with the agent grammatically demoted. ～てある instead keeps the agent human and purposeful but leaves that agent unstated in the background. It carries a "done deliberately and kept that way" meaning that the passive does not.³

ドアが開あけてある。⁵²
"The door has been opened and left so (on purpose)."

ある means "it exists because someone put it there"

ある is the verb of inanimate existence, so ～てある reads as "the result exists there." The result, not the actor, is in focus, but the existence of the result implies a hand that arranged it. This maps the form's meaning directly onto the auxiliary's base sense and makes it easier to remember what ～てある asserts.⁷³

The いる / ある split inside the aspect auxiliaries

Both ～ている and ～てある are the te-form plus an existence verb: いる for animate things, ある for inanimate things. The same animacy split that governs plain existence carries into these aspect auxiliaries, which turn the te-form into a state expression.⁷
