The 〜ている Form: Progress and State

You’ll be able to

Use 〜ている to express an action in progress
Use 〜ている to express a resulting ongoing state
Interpret 〜ている correctly for different verb types

Te-form + いる

Attaching いる to the te-form gives the 〜ている construction, one of the most important aspect forms in Japanese. Its most familiar use is the progressive — an action happening right now: 今、本を読んでいる (Ima, hon o yonde iru, “I am reading a book now”), politely 読んでいます (yonde imasu). In casual speech the い often drops: 読んでる (yonderu). This is essential for describing what people and machines are doing in real time.

A second meaning: resulting state

〜ている does not always mean “-ing.” With certain verbs — especially ones describing an instantaneous change — it expresses a resulting state that continues. 結婚する (kekkon suru, “to get married”) → 結婚している (kekkon shite iru) means “is married,” not “is getting married.” 知る (shiru, “to come to know”) → 知っている (shitte iru) means “know.” 死ぬ (shinu, “to die”) → 死んでいる (shinde iru) means “is dead.” The verb’s meaning decides whether 〜ている reads as ongoing action or ongoing state.

Reading the two meanings

The distinction tracks a verb’s inherent aspect. Durative verbs (activities that take time — 読む read, 食べる eat, 走る run) give the progressive reading with 〜ている: 食べている = “is eating.” Punctual / change-of-state verbs (instant transitions — 結婚する marry, 死ぬ die, 来る come) give the resulting-state reading: 来ている = “has come [and is here].” Also note 〜ている marks habits: 毎日ジョギングをしている (Mainichi jogingu o shite iru, “I jog every day”).

Worked example

Interpret the difference between スマホを見ている (Sumaho o mite iru) and 田中さんを知っている (Tanaka-san o shitte iru). Which is an ongoing action and which is a state?

1.見る (miru, “to look at”) is a durative activity verb, so 〜ている gives the progressive: 見ている = “is looking at.”
2.Thus スマホを見ている means “is looking at [their] smartphone” — an action in progress.
3.知る (shiru) means “to come to know”; it is a change-of-state verb, so 〜ている expresses the resulting state.
4.Thus 田中さんを知っている means “knows Mr. Tanaka” — an ongoing state, not “is getting to know.”

Answer: スマホを見ている = “is looking at the smartphone” (progressive action, from durative 見る). 田中さんを知っている = “knows Mr. Tanaka” (resulting state, from change-of-state 知る). The verb’s aspect, not the 〜ている form itself, decides between “-ing” and a continuing state.

Checkpoint

Your friend says 姉は結婚しています (Ane wa kekkon shite imasu). What does this most naturally mean?

Watch out

Never assume 〜ている = English “-ing.” For change-of-state verbs it means a current state: 知っている = “know” (not “am knowing”), and its negative is 知らない (shiranai, “don’t know”), never 知っていない. Learn which verbs give the state reading.

Checkpoint

Which sentence uses 〜ている to describe an action currently in progress?

On the exam

When narrating a picture or video prompt, 〜ています lets you describe live action: 人々が電車を待っています (Hitobito ga densha o matte imasu, “people are waiting for the train”). Pair it with 今 (ima, “now”) for progress and with change-of-state verbs for states, and your descriptions gain precision.
