The Japanese Te-Form, Explained Simply

What the te-form is

Most Japanese grammar explanations treat the te-form as one item on a long list of conjugations. That framing makes it harder to learn than it needs to be. The te-form is not a tense. It is not a mood. It is a connector. It turns a verb into a bridge between one clause and the next.

Once you understand that, the four main uses of the te-form stop feeling like four separate rules and start feeling like four different things you can connect. You can connect a verb to a request (te-kudasai). You can connect it to an ongoing state (te-iru). You can connect it to the next action in a sequence. You can connect it to a permission question (te-mo ii). The form itself is the same every time. What changes is what you attach afterward.

The te-form is also the gateway into a large family of compound verb patterns in Japanese. Mastering it early pays off for a long time.

Ru-verbs: the easy group

Japanese verbs fall into two main groups plus two irregulars. The first group, called ru-verbs or ichidan verbs, is straightforward. These verbs end in the sound -ru in their dictionary form, and to make the te-form you drop the ru and add te. That is it.

• たべる taberu (to eat) becomes たべて tabete
• みる miru (to see, to look) becomes みて mite
• おきる okiru (to wake up) becomes おきて okite
• ねる neru (to sleep) becomes ねて nete
• でる deru (to leave, to come out) becomes でて dete

One thing to note: not every verb ending in -ru is a ru-verb. Some verbs like かえる kaeru (to return) and はいる hairu (to enter) look like ru-verbs but are actually u-verbs in disguise. The dictionary does not always make this obvious. When you are unsure, check or memorize the group alongside the verb itself.

U-verbs: the sound-change groups

U-verbs, also called godan verbs, are more complex because the final sound determines how the te-form is made. There are five patterns, and learning them as groups is much faster than memorizing each verb individually.

Group 1: ending in u, tsu, or ru - add tte

• かう kau (to buy) becomes かって katte
• まつ matsu (to wait) becomes まって matte
• おわる owaru (to finish) becomes おわって owatte

Group 2: ending in bu, mu, or nu - add nde

• よむ yomu (to read) becomes よんで yonde
• あそぶ asobu (to play) becomes あそんで asonde
• しぬ shinu (to die) becomes しんで shinde

Group 3: ending in ku - add ite

• きく kiku (to listen, to ask) becomes きいて kiite
• かく kaku (to write) becomes かいて kaite
• はたらく hataraku (to work) becomes はたらいて hataraite

Group 4: ending in gu - add ide

• およぐ oyogu (to swim) becomes およいで oyoide
• いそぐ isogu (to hurry) becomes いそいで isoide

Group 5: ending in su - add shite

• はなす hanasu (to speak) becomes はなして hanashite
• かす kasu (to lend) becomes かして kashite
• だす dasu (to take out) becomes だして dashite

Irregular verbs and the iku exception

Japanese has two main irregular verbs. Both are used constantly, so their te-forms become automatic very quickly.

• する suru (to do) becomes して shite
• くる kuru (to come) becomes きて kite

The one exception worth flagging is いく iku (to go). By the rules of Group 3, you might expect it to become iite. It does not. It is itte, which looks like the tte-group result for a verb ending in -tsu or -u. This is the one exception to the ku-to-ite pattern and it is common enough that you will encounter it immediately. Memorize iku to itte as a unit and move on.

• いく iku (to go) becomes いって itte (exception)

Te-kudasai: polite requests

The simplest and most immediately useful application of the te-form is making polite requests. Attach kudasai to the te-form of any verb and you get a polite imperative.

• みてください mite kudasai - Please look at this.
• まってください matte kudasai - Please wait.
• きいてください kiite kudasai - Please listen.
• はなしてください hanashite kudasai - Please speak. (often used to mean speak more slowly)
• かいてください kaite kudasai - Please write it.

Te-kudasai is polite but still directive. In very formal situations or when addressing someone significantly senior, the softer form te-itadakemasen ka (would you not receive doing X for me?) is preferred. For everyday use, te-kudasai is appropriate and correct.

You will also hear the shorter te alone used as a casual request between close friends. Mite means look in an informal context. Matte means wait. This informal version drops the kudasai entirely.

Te-iru: the progressive and ongoing states

Attach iru to the te-form and you get te-iru, which covers two different meanings depending on the type of verb you use.

With action verbs, te-iru expresses that something is happening right now or repeatedly over time.

• たべています tabete imasu - I am eating (right now).
• はたらいています hataraite imasu - I am working.
• にほんごをべんきょうしています nihongo wo benkyou shite imasu - I am studying Japanese.

With change-of-state verbs, te-iru describes the result of a completed change, not an ongoing action.

• けっこんしています kekkon shite imasu - I am married. (not: I am in the process of marrying)
• しんでいます shinde imasu - It is dead. (the state that resulted from dying)
• まどがあいています mado ga aite imasu - The window is open. (the resulting state of being opened)

In spoken Japanese, te-iru is often contracted to te-ru. You will hear tabete ru and hataraite ru constantly in casual speech. Both are correct; te-iru is the full form and te-ru is the contracted spoken form.

Linking sequential actions

The te-form can connect two or more actions in order. The first verb takes the te-form; the final verb carries the tense for the whole sentence. The actions are understood to happen in the order they appear.

• あさおきて、はをみがきます asa okite, ha wo migakimasu - I wake up in the morning and brush my teeth.
• としょかんにいって、ほんをよみます toshokan ni itte, hon wo yomimasu - I go to the library and read a book.
• シャワーをあびて、ごはんをたべて、がっこうにいきます shawaa wo abite, gohan wo tabete, gakkou ni ikimasu - I take a shower, eat, and go to school.

Notice that in the third example, two te-form verbs appear before the final verb. You can chain as many as you need. The final verb is the one that marks whether the sentence is present, past, or polite.

Linking with the te-form implies a neutral connection between actions. It does not carry the same causal weight as because or so. If you want to express cause and effect, you need a different connector. For simple sequencing, the te-form is the natural choice.

Te-mo ii: asking permission

Adding mo ii ka to the te-form turns it into a permission question. The literal meaning is something like is it okay if I do X. In practice it functions as may I or is it alright to.

• はいってもいいですか haitte mo ii desu ka - May I come in?
• つかってもいいですか tsukatte mo ii desu ka - May I use this?
• ここにすわってもいいですか koko ni suwatte mo ii desu ka - Is it okay if I sit here?
• しゃしんをとってもいいですか shashin wo totte mo ii desu ka - May I take a photo?

The affirmative reply is ii desu yo (it is fine) or mochiron (of course). The negative is dame desu (it is not okay) or, more softly, chotto (a little, used as a polite refusal without stating the reason directly).

You can also use te-mo ii to give permission to someone else. Tabete mo ii yo means you can eat it, go ahead. The direction changes but the structure is the same.

Putting it all together

The te-form is one of the first grammar structures where the payoff is immediate and obvious. Within your first week of learning it, you can make requests, describe ongoing actions, sequence events, and ask permission. That covers a significant share of daily conversation at the beginner level.

The formation rules take most learners a session or two to internalize. The patterns are genuinely consistent, and the only tricky part is the iku exception and the handful of u-verbs that look like ru-verbs. Both are fixed with exposure rather than memorization effort. You encounter these verbs so often that the correct form becomes automatic.

If you are drilling verb conjugations with spaced repetition, the te-form is a good candidate for a dedicated card set. Inku covers N5 and N4 vocabulary with FSRS scheduling, which means the verbs you review stay calibrated to what you are close to forgetting rather than what you already know well. The same principle applies to conjugation practice: a handful of targeted reviews is more effective than a long session with the same chart.

From here, the te-form opens into a wider set of patterns. Te-ageru and te-morau express giving and receiving favors. Te-shimau describes an action done completely, often with a nuance of regret. Te-oku describes doing something in advance. Each of these is its own topic, but all of them sit on the same foundation you just built.
