Expressing Desire: "I want to..." (~tai)

Drop 'masu', add 'tai' to say what YOU want to do, treating the whole word like an adjective.

Grammar Rule in 30 Seconds

To say 'I want to' in Japanese, remove the final 'u' from a verb and add 'tai'.

  • Drop the 'u' from the dictionary form: {食べる|たべる} -> {食べ|たべ} + たい = {食べたい|たべたい}.
  • It conjugates like an i-adjective: {食べたい|たべたい} (want to eat), {食べたくない|たべたくない} (don't want to eat).
  • Use the particle 'ga' or 'o' to mark the object of your desire.
Verb(stem) + たい (tai)

Overview

Japanese offers nuanced ways to express personal desire. The suffix ~tai (~たい) is fundamental for articulating your wish to perform an action, translating directly to "I want to [verb]." Unlike English, where "want" often acts as an independent verb followed by an infinitive, Japanese integrates this expression of desire directly into the action itself. This structural difference is key: attaching ~tai to a verb stem transforms that verb into an i-adjective (い形容詞(いけいようし)).

This transformation is crucial because it dictates how sentences with ~tai are conjugated and used, mirroring the grammatical rules for adjectives like oishii (美味しい(おいしい) – delicious) or samui (寒い(さむい) – cold). At its core, ~tai indicates a first-person, internal, and often emotional urge or longing to engage in an activity. It reflects a personal intention driven by feeling, distinguishing it from mere plans or obligations.

For instance, sushi o tabetai (寿司(すし)食べたい(たべたい) – "I want to eat sushi") clearly frames the action of eating as the object of your desire, not just the sushi itself.

How This Grammar Works

Understanding ~tai hinges on its morphological transformation of verbs into i-adjectives. When ~tai appends to a verb stem, the resulting construction sheds its verbal properties and behaves precisely like an i-adjective. This is not a superficial change; it profoundly impacts conjugation and modification possibilities.
For example, miru (見る(みる) – to see/watch) becomes mitai (見たい(みたい) – want to see/watch). Just as oishii can be conjugated to oishikunai (美味しくない(おいしくない) – not delicious) or oishikatta (美味しかった(おいしかった) – was delicious), mitai follows an identical pattern: mitakunai (見たくない(みたくない) – don't want to see/watch) and mitakatta (見たかった(みたかった) – wanted to see/watch).
This i-adjective behavior means ~tai forms can directly modify nouns, similar to any other adjective. For instance, mitai eiga (見たい映画(みたいえいが) – movie I want to see) literally translates to "see-desiring movie." You can also connect clauses using its ~te form, ~takute (~たくて), to express sequential actions or reasons, much like oishikute (美味しくて(おいしくて) – being delicious, and...). This foundational understanding unlocks ~tai's versatility within Japanese grammar.
Crucially, ~tai is primarily reserved for expressing your own desires. Japanese grammar inherently distinguishes between direct experience (your internal feelings) and inferred experience (others' feelings). Because you have direct access to your own internal state, you can confidently state watashi wa oyogitai ((わたし)泳ぎたい(およぎたい) – I want to swim).
However, you cannot directly know someone else's internal desires. Using ~tai for a third person, such as Kare wa oyogitai ((かれ)泳ぎたい(およぎたい) – He wants to swim), sounds unnatural, even presumptuous, implying an unwarranted insight into their inner thoughts. For expressing others' desires, a different grammatical form, ~tagaru (~たがる), is employed.
This form acknowledges that you are observing their desire based on outward signs rather than directly experiencing it. This distinction is a cornerstone of Japanese interpersonal communication and reflects a linguistic emphasis on evidentiality.

Formation Pattern

1
The formation of ~tai is systematic and follows a clear pattern. You attach ~tai directly to the masu-stem (also known as the pre-masu form or conjunctive form) of a verb. The masu-stem is what remains after you remove ~masu from the polite non-past ~masu form of a verb.
2
Steps for Formation:
3
Start with the verb's polite non-past form (e.g., iku 行く(いく) becomes ikimasu 行きます(いきます) – to go).
4
Remove ~masu (e.g., iki 行き(いき)). This is the masu-stem.
5
Attach ~tai (e.g., ikitai 行きたい(いきたい) – want to go).
6

Irregular Verbs:
21
Verbs that appear irregular in other conjugations, such as suru (する(する) – to do) and kuru (来る(くる) – to come), adhere to the same masu-stem rule when forming ~tai.
22
suru: shimasu (します(します)) → shi (()) → shitai (したい(したい) – want to do).
23
kuru: kimasu (来ます(きます)) → ki (()) → kitai (来たい(きたい) – want to come).
24
Important Note on Particles:
25
When an action modified by ~tai involves a direct object, you typically have a choice between the particles o (を) and ga (が).
26
o (を): Emphasizes the action of wanting to do something to the object. It highlights the verb's transitive nature. For example, Pītsa o tabetai. (ピザ(ぴざ)食べたい(たべたい)。- I want to eat pizza.) focuses on the act of eating pizza.
27
ga (が): Emphasizes the object itself as the specific item you desire to act upon. It can imply a stronger, more immediate craving or highlight the object as the sole focus of desire. For example, Pītsa ga tabetai. (ピザ(ぴざ)食べたい(たべたい)。- Pizza is what I want to eat.) emphasizes pizza as the thing you want. Both are often interchangeable in casual speech, but ga is almost always preferred for the object when the ~tai form is negative (~takunai). This shift in particle usage reflects the ~tai form's adjectival nature, where ga often marks the subject or object of desire/feeling for adjectives.

When To Use It

You should employ ~tai when, as the speaker, you wish to articulate a personal, internal desire or aspiration to perform an action. This grammatical structure is versatile but carries specific implications regarding politeness, formality, and perspective.
  • 1. Expressing Your Own Immediate Desires and Needs: This is the most common and direct application. Use ~tai to articulate what you want to do right now or in the near future.
  • Kōhī ga nomitai desu. (コーヒー(こーひー)飲みたい(のみたい)です。- I want to drink coffee.) – A polite statement of desire.
  • Hayaku kaeritai. (早く(はやく)帰りたい(かえりたい)。- I want to go home quickly.) – A casual expression of a strong wish.
  • 2. Stating Personal Goals and Aspirations: ~tai is also suitable for expressing long-term goals or general accomplishments you wish to achieve. This demonstrates personal ambition.
  • Nihon de hatarakitai to omotte imasu. (日本(にほん)働きたい(はたらきたい)思って(おもって)います。- I'm thinking I want to work in Japan.) – Expressing an ongoing aspiration.
  • Raigetsu, Kyōto ni ikitai desu. (来月(らいげつ)京都(きょうと)行きたい(いきたい)です。- I want to go to Kyoto next month.) – A future goal.
  • 3. Asking Casual Questions About Others' Desires (Close Relationships): While primarily first-person, ~tai can be used in casual questions when addressing someone of equal or lower status, such as friends, family members, or juniors. This is acceptable because you are directly asking them to reveal their own internal desire, not presuming it. However, this usage is restricted contextually.
  • Nani ga shitai? ((なに)したい(したい)?- What do you want to do?) – Very casual, typical among friends.
  • Issho ni eiga o mitai? (一緒(いっしょ)映画(えいが)観たい(みたい)?- Do you want to watch a movie together?) – A casual invitation.
  • Crucial Caveat: Using ~tai in questions with superiors or strangers is generally too direct, potentially presumptuous, or even rude, as it interrogates their internal feelings. In such contexts, more indirect or formal expressions of invitation or inquiry (~masen ka {~ませんか}, ikaga desu ka {いかがですか}) are preferred.
  • 4. Modifying Nouns (Adjectival Usage): Because ~tai transforms into an i-adjective, it can directly precede and modify nouns, functioning identically to any other adjective.
  • Nomitai dake nominasai. (飲みたい(のみたい)だけ飲みなさい(のみなさい)。- Drink as much as you want.) – Here, nomitai modifies dake (amount).
  • Kono aida yomitai hon ga mitsukatta. (この間(このあいだ)読みたい本(よみたいほん)見つかった(みつかった)。- I found the book I wanted to read the other day.) – yomitai modifies hon (book).
Contextual Nuances and Politeness:
  • Adding desu (です(です)) to the ~tai form makes it polite, suitable for general interactions: Tabetai desu. (食べたい(たべたい)です。).
  • Without desu, the form is casual: Tabetai. (食べたい(たべたい)。).
  • For very strong or wistful desires, you can append particles like na (()) or (なあ(なあ)) to the casual form: Ikitai nā. (行きたい(いきたい)なあ。- Oh, I really want to go...).
  • The choice between o (を) and ga (が) for the object particle subtly shifts emphasis, as detailed in the Formation section. ga is often chosen when the desire is particularly strong or focused on the item itself.

Common Mistakes

Learners of Japanese frequently encounter specific pitfalls when first employing ~tai. Mastering these distinctions is crucial for natural and accurate expression, allowing you to avoid common grammatical errors that can sound unnatural to native speakers.
  • 1. The "Third Person" Trap: Applying ~tai to Others' Desires
This is arguably the most frequent and significant error. As extensively discussed, ~tai expresses the speaker's internal, firsthand desire. Japanese grammar maintains a clear boundary between one's own experiences and observed experiences of others. You cannot directly know another person's internal feelings or desires. Therefore, using ~tai for anyone other than yourself (or sometimes in direct casual questions to a close peer) is grammatically incorrect and sounds presumptuous, like claiming to read their mind.
  • Incorrect: Kare wa kōhī o nomitai desu. ((かれ)コーヒー(こーひー)飲みたい(のみたい)です。) – This implies you are privy to his internal desire, which is linguistically impossible in Japanese.
  • Correct: Kare wa kōhī o nomitagatte imasu. ((かれ)コーヒー(こーひー)飲みたがって(のみたがって)います。- He seems to want to drink coffee.)
  • Explanation: For observing and stating others' desires, you must use ~tagaru (~たがる). ~tagaru literally means "to show signs of wanting" or "to act as if one wants," indicating an observation based on outward behavior or indirect information, rather than direct knowledge of their inner state. The suffix ~garu (~がる) attaches to i-adjectives (including the ~tai form's stem, e.g., tabetaitabetagaru) to express that someone appears to be feeling that way.
  • 2. The "I Want You To Do" Trap: Confusing Your Desire with Wanting Someone Else to Act
A common misconception is attempting to use ~tai to mean "I want you to [verb]." Remember, ~tai always signifies that you, the speaker, want to perform the action. It never refers to wanting someone else to act.
  • Incorrect: Kimi ni benkyō shitai. ((きみ)勉強(べんきょう)したい(したい)。) – This is grammatically nonsensical, as ~tai refers to the speaker's desire to study for themselves, not wanting someone else to study.
  • Correct: Kimi ni benkyō shite hoshii. ((きみ)勉強(べんきょう)してほしい(ほしい)。- I want you to study.)
  • Explanation: To express that you want someone else to perform an action, you need to use the ~te hoshii (~てほしい) pattern. This literally translates to "I want [thing/action] from you." It combines the ~te form of the verb with hoshii (ほしい(ほしい)), an i-adjective meaning "desirable."
  • 3. The "Noun" Trap: Using ~tai for Things Instead of Actions
~tai is exclusively used for desiring actions (verbs). You cannot attach ~tai directly to a noun to express wanting a thing. The grammatical function of ~tai is to modify a verb's stem.
  • Incorrect: Neko tai. ((ねこ)たい(たい)。) – This is grammatically broken; ~tai cannot attach directly to a noun.
  • Correct: Neko ga hoshii. ((ねこ)ほしい(ほしい)。- I want a cat.)
  • Explanation: To express wanting a noun (a thing), you must use the i-adjective hoshii (ほしい(ほしい) – desirable). It typically takes the particle ga (が) to mark the desired item, indicating that the noun itself is the object of your desire.
  • 4. Incorrect Conjugation as a Verb:
Once ~tai is attached to a verb stem, the resulting form functions as an i-adjective. Attempting to conjugate it using verb conjugation rules is a common and fundamental mistake. You must apply i-adjective conjugation rules for all subsequent modifications (negative, past, etc.).
  • Incorrect (mixing verb negation): Tabeitai nai. (食べたい(たべたい)ない。)
  • Correct (i-adjective negative): Tabetakunai. (食べたくない(たべたくない)。)
  • Incorrect (mixing polite verb past negative): Tabetai masen deshita. (食べたい(たべたい)ませんでした。)
  • Correct (i-adjective polite past negative): Tabetakunakatta desu. (食べたくなかった(たべたくなかった)です。) or simply Tabetakatta desu. (食べたかった(たべたかった)です。) for polite past positive. Always remember that the ~tai form is an i-adjective and should be conjugated as such.

Real Conversations

~tai is an integral part of daily Japanese, reflecting personal desires across various social contexts, from casual chats to polite requests. Observing its use in natural dialogue helps solidify understanding of its practical application.

1. Casual Conversation (Friends planning an outing):

- A: Kinyōbi no yoru, nani shitai? (金曜日(きんようび)(よる)(なに)したい(したい)?- Friday night, what do you want to do?)

- B: Eiga mitai na. Nani ka omoshiroi no aru kana? (映画(えいが)観たい(みたい)な。何か(なにか)面白い(おもしろい)のあるかな?- I want to watch a movie. Is there anything interesting, I wonder?)

- A: Jā, ichiban atarashii horā eiga wa? Kimi, horā suki datta yo ne? (じゃあ、一番(いちばん)新しい(あたらしい)ホラー映画(ほらーえいが)は?(きみ)ホラー(ほらー)好き(すき)だったよね?- Then, how about the newest horror movie? You liked horror, right?)

- B: Uーん、 kyō wa soko made kowai no mitakunai kamo. (うーん、今日(きょう)はそこまで怖い(こわい)のは観たくない(みたくない)かも。- Hmm, today I might not want to watch something that scary.)

- Observation: This exchange demonstrates informal ~tai and ~takunai for direct and shared desires among friends. The na (()) particle adds a soft, reflective tone, common in casual expressions of desire or thought.

2. At a Restaurant (Ordering food politely):

- Customer: Sumimasen, ramen o tabetai n desu ga... osusume wa arimasu ka? (すみません(すみません)ラーメン(らーめん)食べたい(たべたい)んですが…おすすめ(おすすめ)はありますか?- Excuse me, I want to eat ramen, but... do you have any recommendations?)

- Waiter: Hai, kochira no karamiiso ramen wa ikaga desu ka? Ichiban ninki desu yo. (はい(はい)、こちらの辛味噌(からみそ)ラーメン(らーめん)はいかがですか?一番(いちばん)人気(にんき)ですよ。- Yes, how about this spicy miso ramen? It's our most popular.)

- Observation: ~tai n desu ga (~たいんですが) is a very common polite way to express a desire while gently leading into a question or request. The n desu ga (んですが) adds a sense of asking for advice or carefully stating a situation, making the approach softer and more deferential.

3. Workplace (Manager asking about a team member's preference):

- Manager: Kondo no purojekuto, Suzuki-san wa doko o tantō shitai desu ka? (今度(こんど)プロジェクト(ぷろじぇくと)鈴木(すずき)さんはどこを担当(たんとう)したい(したい)ですか?- For the next project, Suzuki-san, what part do you want to be in charge of?)

- Suzuki: Watashi wa atarashii gijutsu o tsukaitai no de, kaihatsu o kibo shimasu. ((わたし)新しい(あたらしい)技術(ぎじゅつ)使いたい(つかいたい)ので、開発(かいはつ)希望(きぼう)します。- Since I want to use new technology, I hope for development.)

- Observation: While ~tai is primarily for the first person, a manager can use ~tai desu ka (~たいですか?) when directly inquiring about a subordinate's own desire, as they are asking the individual to articulate their internal state. Suzuki-san then uses ~tai to state her preference. The no de (ので(ので)) provides a reason for her choice, offering a natural flow.

4. Social Media (Comment on a travel photo):

- Commenter: Uwaa, kono keshiki meccha kirei! Watashi mo koko ni ikitai! (うわー、この景色(けしき)めっちゃきれい(きれい)(わたし)もここに行きたい(いきたい)!- Wow, this scenery is super beautiful! I want to go here too!)

- Observation: ~tai is naturally suited for expressing immediate, emotional reactions and desires on social media platforms. Meccha (めっちゃ) serves as a very casual intensifier, commonly found in informal online contexts.

Quick FAQ

  • Q: Can I use ~tai to ask a stranger or superior what they want to do?
  • A: Generally, no. Using ~tai ka (~たいか) directly with a stranger or superior can sound overly familiar, direct, or even presumptuous. It implies you are probing their internal desires. Instead, opt for more indirect or humble expressions. For example, to politely ask "Would you like to go?" to a superior, you might use Ikimasen ka? (行きませんか(いきませんか)?- Won't you go? / Shall we go?), or other honorific forms like Oiki ni narimasu ka? (お行きになりますか(おいきになりますか)?).
  • Q: How do I express "I don't want to go anywhere"?
  • A: You would say Doko ni mo ikitakunai. (どこ(どこ)にも行きたくない(いきたくない)。) The particle ni mo (にも) combined with doko (どこ(どこ) – where) creates the meaning "not anywhere" or "nowhere." The ~kunai form is the standard negative conjugation for i-adjectives.
  • Q: What's the difference between ~tai and ~tsumori (つもり(つもり))?
  • A: ~tai expresses a desire or wish ("I want to..."), stemming from an internal feeling. ~tsumori (つもり(つもり)) expresses a plan or intention ("I intend to..." / "I plan to..."), indicating a more concrete, decided course of action.
  • Eiga o mitai. (映画(えいが)観たい(みたい)。- I want to watch a movie.) – A desire.
  • Eiga o miru tsumori desu. (映画(えいが)観る(みる)つもり(つもり)です。- I plan to watch a movie.) – A concrete intention.
~tsumori implies a more resolute and less emotional state than ~tai.
  • Q: Can ~tai be used for hypothetical desires, like "If I were rich, I'd want to travel"?
  • A: Yes, absolutely. You can combine ~tai with conditional forms to express hypothetical desires. For example: Okane ga attara, sekai o ryokō shitai. (お金(おかね)あったら(あったら)世界(せかい)旅行(りょこう)したい(したい)。- If I had money, I'd want to travel the world.) This demonstrates the flexibility of ~tai beyond immediate desires.
  • Q: Is there a polite form for "I don't want to..."?
  • A: Yes. Just like any other i-adjective, you add desu (です(です)) to the negative form: ~takunai desu (~たくないです). For example, Tabetakunai desu. (食べたくない(たべたくない)です。- I don't want to eat.) This is a polite refusal. For an even softer refusal, especially in social contexts, you might add chotto (ちょっと(ちょっと) – a little bit), like Chotto tabetakunai desu. (ちょっと(ちょっと)食べたくない(たべたくない)です。- I don't really want to eat.).
  • Q: What about the particles o (を) and ga (が) when ~tai is negative?
  • A: When ~tai is in its negative form (~takunai), the particle ga (が) is almost always preferred for marking the object. This is a strong tendency in Japanese, often reflecting the adjectival nature of the ~tai form. While o (を) can technically be used, ga is significantly more natural and common in negative desire statements, emphasizing that the object itself is not desired to be acted upon.
  • Kōhī ga nomitakunai. (コーヒー(こーひー)飲みたくない(のみたくない)。- I don't want to drink coffee.)

Both are fine. 'Ga' emphasizes the object.

Change 'tai' to 'takatta'.

No, use 'hoshii' for nouns.

Add 'desu' to make it polite.

Because it ends in 'i' and conjugates like one.

Use 'takunai'.

Yes, with 'desu'.
