Intransitive + ている: Resultant State

You already know ている as the "-ing" marker: 走っている means "is running." So a beginner meeting ドアが開いている naturally reads it as "the door is opening" — and gets it wrong. For a verb like 開く, which describes an instantaneous change, ている does not mean the change is unfolding; it means the change already happened and its result is still standing: the door is open. This resultant-state reading is the natural Japanese way to describe how things are, and it hinges entirely on pairing the intransitive verb of a pair with ている.

English says "is open"; Japanese says "has opened and stays that way"

English describes a static condition with be + an adjective or past participle: "the door is open," "the light is on," "the window is broken." Japanese has adjectives too, but for these change-of-state situations it prefers a verb construction: the intransitive verb (which names the change) plus ている (which says the result persists). Literally it's "is in the state of having opened."

Note the particle: because these are intransitive verbs, the thing that changed takes が. No agent appears anywhere — that's the whole point of using the intransitive.

Why ている flips between "-ing" and "is (state)"

ている is genuinely ambiguous, and which meaning you get depends on the kind of verb, not on ている itself. This is the concept English never trains you for. Verbs split by their inherent aspect (Aktionsart):

• Durative activities — running, eating, reading — take time to unfold. With these, ている = progressive ("is doing"). 走っている = "is running."
• Instantaneous changes — opening, breaking, dying, arriving — happen in a flash and then leave a result. With these, ている = resultant state ("is now in the resulting condition"). 開いている = "is open."

The most famous examples of the resultant reading are 結婚している ("is married," not "is getting married") and 死んでいる ("is dead," not "is dying"). If ている worked like English "-ing," these would be nonsense; instead they show ている doing exactly what it does — reporting the standing result of a completed change.

The everyday resultant-state verbs

These change-of-state intransitives describe the world around you all day long. Practice reading each as a current condition, never as an action underway.

Look at 落ちている: English would say "a wallet is on the road," a pure location statement. Japanese chooses 落ちている — "has fallen and lies there" — quietly telling you the wallet ended up there by dropping, not by being placed. The verb carries a whole backstory that English flattens into "is."

Why English speakers reach for the wrong tense

English gives you three tools for these situations and none of them lines up cleanly with Japanese. "The door is open" uses an adjective and says nothing about how it got that way. "The door has opened" uses the present perfect and focuses on the past event. "The door is opening" uses the progressive and describes motion. Japanese 開いている is closest to the first — it describes a current condition — but it's built from the verb of change plus ている, so it silently carries the "it opened" event inside it, the way the present perfect does. That hybrid is why beginners keep mis-slotting it: their instinct grabs the progressive ("is opening") because of the surface resemblance to 走っている. Retrain the instinct by remembering that for a snap-change verb, ている can only look backward to the change and report the state it left.

The negative: 〜ていない means "not yet in that state"

The negative of a resultant state is not "isn't doing" but "the change hasn't happened yet." ドアが開いていない = "the door isn't open (it never opened)."

This "not yet" flavor is why 食べていない usually means "haven't eaten (yet)," not "am not eating right now" — the same result-oriented logic. See the negative-state page for more.

How this contrasts with 〜てある

There's a near-twin construction you'll meet next. 自動詞 + ている reports a state with no one behind it; 他動詞 + てある reports a state someone deliberately produced. Compare 窓が閉まっている ("the window is shut" — just a fact) with 窓が閉めてある ("the window has been shut" — someone shut it on purpose). Both describe the same closed window, but てある smuggles in a hidden agent and intention. That contrast gets its own page: transitive + てある.

Common Mistakes

Key Takeaways

• 自動詞 + ている on a change-of-state verb = the lingering result of a completed change: 開いている = "is open," not "is opening."
• ている is progressive for durative verbs (走っている) but resultant-state for punctual ones (止まっている, 結婚している, 死んでいる); the verb decides.
• The changed thing takes が, and no agent is present — that's the essence of the intransitive framing.
• 〜ていない means "the change hasn't happened yet" (まだ来ていない = "hasn't come / isn't here yet").
• Contrast with 他動詞 + てある, which adds a deliberate, hidden agent to the same kind of state.
