Meaning & Usage
Pick up any Japanese novel or turn on any drama and you will encounter ている within moments. The pattern ～ている (read as te iru) is formed by combining the て-form of a verb with いる (to exist, used for animate beings). Beginners often learn it as "the Japanese -ing form" — that captures the first function, but misses the other two.
Function 1: Progressive Actions. The most familiar use is expressing an action currently in progress. Someone eating right now: 食べている. Someone reading at this moment: 本を読んでいる. This maps almost directly onto English "is doing" and is the easiest function to grasp at N5 level.
Function 2: Resultant States. Here ている diverges sharply from English. Many Japanese verbs describe a transition — 結婚する (to marry), 開く (to open), 死ぬ (to die), 着る (to put on clothing). With these verbs, ている does not mean the action is ongoing. It means the state that resulted from that action continues into the present. 結婚している means "is married" — the wedding happened in the past, but the resulting state persists. 窓が開いている means "the window is open" — someone opened it, and it remains that way. This resultant state usage appears frequently on the JLPT and trips up many learners.
Function 3: Habitual Actions. ている also describes actions that happen regularly. 毎日運動している means "I exercise every day" — not that the person is exercising at this exact moment, but that it is a regular part of life. The parallel in English is the simple present for habits: "I drink coffee every morning."
The polite form is ています; the plain form is ている. In casual spoken Japanese, ている contracts to てる — 食べてる instead of 食べている. You will hear this contraction constantly in daily conversation. In formal writing, business settings, or polite speech, the full ています is always preferred. Switching naturally between てる and ています is one of the clearer signs of growing fluency.
A helpful shortcut: think of ている as a lens showing the current relationship between a subject and a verb. For action verbs (eating, running, writing), it shows an action unfolding right now. For transition verbs (opening, marrying, arriving), it shows the current state that a past event created.
Structure & Formation
The base pattern is: Verb (て-form) + いる
To use ている, you must first convert the verb to its て-form. The rules depend on the verb group:
| Verb Group | Ending | Rule | Example |
|---|---|---|---|
| る-verbs (Group 2) | ～る | Drop る, add て | 食べる → 食べて |
| う-verbs (Group 1) | ～う、～つ、～る | Replace with って | 買う → 買って |
| う-verbs (Group 1) | ～む、～ぬ、～ぶ | Replace with んで | 飲む → 飲んで |
| う-verbs (Group 1) | ～く | Replace with いて | 書く → 書いて |
| う-verbs (Group 1) | ～ぐ | Replace with いで | 泳ぐ → 泳いで |
| う-verbs (Group 1) | ～す | Replace with して | 話す → 話して |
| Irregular | する | → して | する → して |
| Irregular | くる | → きて | 来る → 来て |
After forming the て-form, the full conjugation set is:
- Plain affirmative: Verb-て + いる (e.g., 食べている)
- Polite affirmative: Verb-て + います (e.g., 食べています)
- Casual contraction: Verb-て + る (e.g., 食べてる)
- Plain negative: Verb-て + いない (e.g., 食べていない)
- Polite negative: Verb-て + いません (e.g., 食べていません)
- Past progressive: Verb-て + いた (e.g., 食べていた — was eating)
- Polite past: Verb-て + いました (e.g., 食べていました — was eating, polite)

Common Mistakes
Mistake 1: Using the Dictionary Form Instead of ている for Ongoing Actions
❌ 今、ご飯を食べる。
✅ 今、ご飯を食べている。
The dictionary form alone does not express that an action is happening right now. 食べる sounds like a general statement ("I eat") or a future intention ("I will eat"). To say you are currently in the middle of eating, use 食べている. For any action happening at this very moment, ている is required.
Mistake 2: Incorrect て-form for 行く (to go)
❌ 学校に行いている。
✅ 学校に行っている。
The verb 行く (to go) is a well-known exception to the く→いて rule. Most く-ending verbs use いて (e.g., 書く → 書いて), but 行く becomes 行って — never 行いて. This is one of the most common て-form errors at the beginner level. Memorize it early and move on.
Mistake 3: Using Simple Past Instead of ている for Resultant States
❌ 窓が開いた。 (when meaning "the window is open")
✅ 窓が開いている。
開いた (opened) focuses on the moment the action occurred — "the window opened" as a past event. To describe the current situation — "the window is open right now" — you need ている. This gap between a past event (た) and the state it left behind (ている) runs throughout everyday Japanese.
Mistake 4: Forgetting ている for Wearing Verbs
❌ 彼は赤いシャツを着る。
✅ 彼は赤いシャツを着ている。
Wearing is a resultant state in Japanese — you put clothes on (a completed action) and remain in that state. Plain 着る sounds like "will put on" or a habitual action, not "is wearing right now." Other clothing verbs follow the same pattern: はく (pants/shoes), かける (glasses), かぶる (hats). All require ている to describe what someone is currently wearing.
Mistake 5: Using ている for Fully Completed Past Actions
❌ 昨日、映画を見ている。
✅ 昨日、映画を見た。
Watching a movie yesterday is a finished action — nothing carries into the present. Use simple past た for that. Reserve ていた for actions that were in progress at a past moment: 昨日、映画を見ていた (I was watching a movie yesterday).
Cultural Notes
In casual conversation, てる is the default. Using the full ている among friends can sound slightly stiff. Text someone and you will write 何してる？ not 何をしていますか？. Learning to feel the difference — and switch registers without thinking — is one of the clearer signs of growing fluency.
ている is also the backbone of Japanese self-introductions. 東京に住んでいます, 会社で働いています — these phrases describe ongoing states that define who you are right now. In these cases, ている is not saying the action is happening as you speak. It describes an enduring situation that frames your current life.
One practical way to internalize ている versus た: watch Japanese drama or anime and notice which form characters use. Native speakers switch automatically. Paying attention to those choices — asking yourself why た works there, or why ている is right here — builds intuition faster than memorizing rules alone.

JLPT Tips
On the JLPT N5 exam, ている appears in reading passages, grammar-choice questions, and listening sections. The core skill tested is identifying which meaning applies in context — progressive, resultant state, or habitual. A few guidelines make that judgment faster.
Time words are your first clue. Expressions like 今 (now), ちょうど (just now), and 今ごろ (around now) point strongly to a progressive action at this moment. When you spot these adverbs in a question, expect the progressive meaning.
When a sentence describes someone's living situation, profession, appearance, or relationship status, ている is almost certainly expressing a resultant state or habitual situation. State-change verbs worth memorizing: 結婚する (marry), 住む (reside), 知る (come to know), 着る (put on), 死ぬ (die). In ている form, these almost always describe a current state, not an ongoing action.
Pay close attention to 知っている (shitte iru, "to know"). Unlike English, Japanese uses ている to express the state of knowing something. The negative, however, is 知らない (shiranai, "don't know") — not 知っていない. This irregular negative is a common trap on N5 and N4. Memorize the pair — 知っている / 知らない — as a single unit.
