The Japanese verb 待つ (matsu), meaning “to wait,” is a fundamental godan (Group 1) verb essential for everyday conversations. As a tsu-ending verb, it follows specific patterns that differ from simpler ichidan verbs, making it a perfect example for understanding core conjugation rules. This guide provides an original, in-depth exploration of its forms, from basic polite speech to complex conditionals, with tables, examples, and tips for practical use.
Understanding Godan Verbs Like Matsu
Godan verbs, also called u-verbs, change their final syllable across five vowel rows (a, i, u, e, o) during conjugation, unlike ichidan verbs which simply drop -ru. Matsu ends in -tsu, so its stem shifts to machi or mat- depending on the form. The dictionary form is 待つ (matsu), used in casual speech.
Key characteristics:
- Belongs to the tsu-row in the go-dan system.
- Transitive and commonly used in phrases like バスを待つ (basu o matsu, wait for the bus).
- Requires memorizing row-specific changes for accuracy.
Mastering matsu builds confidence for similar verbs like 立つ (tatsu, to stand) or 持つ (motsu, to hold).
Basic Forms: Dictionary, Stem, and Polite Masu
Start with essentials. The dictionary form 待つ expresses present/future actions informally: 私は待つ (watashi wa matsu, I wait). The stem is machi- for many polite forms.
The masu form (待ちます, machimasu) is polite and standard for formal settings. Drop the -tsu and add -i + masu.
| Form | Plain | Polite | Example |
|---|---|---|---|
| Present | 待つ (matsu) | 待ちます (machimasu) | 電車を待ちます (Densha o machimasu, I wait for the train.) |
| Stem | 待 (mat/machi) | – | Used in compounds like 待ち合わせ (machiawase, meeting point). |
Expressing the Past: Ta-Form Conjugations
Past tense uses the ta-form. For tsu-ending godan verbs like matsu, it becomes 待った (matta, waited). Polite version: 待ちました (machimashita).
Examples:
- 昨日、友達を待った (Kinō, tomodachi o matta, I waited for my friend yesterday.)
- 会議を待ちました (Kaigi o machimashita, I waited for the meeting.)
| Affirmative | Negative | |
|---|---|---|
| Plain Past | 待った (matta) | 待たなかった (matanakatta) |
| Polite Past | 待ちました (machimashita) | 待ちませんでした (machimasen deshita) |
This form is crucial for storytelling and recounting events.
Te-Form: Connecting Actions and Requests
The te-form 待って (matte) links verbs or makes requests. For matsu, change -tsu to -tte. Use in progressives like 待っている (matte iru, waiting) or polite pleas: 待ってください (matte kudasai, please wait).
Practical uses:
- Sequential: 本を読んで待って (Hon o yonde matte, read the book and wait.)
- Progressive polite: 待っています (matte imasu, I am waiting now.)
Negatives: Denying the Wait
Negative plain: 待たない (matanai, don’t wait). Follows tsu → ta + nai pattern. Polite: 待ちません (machimasen).
| Form | Affirmative | Negative Plain | Negative Polite |
|---|---|---|---|
| Present | 待つ/待ちます | 待たない | 待ちません |
| Past | 待った/待ちました | 待たなかった | 待ちませんでした |
Example: もう待たない (Mō matanai, I won’t wait anymore.)
Potential and Volitional Forms
Can wait? 待てる (materu, potential). Let’s wait: 待とう (matō, volitional plain) or 待ちましょう (machimashō, polite).
- 待てるよ (Maseru yo, I can wait.) – Expressing ability.
- 一緒に待ちましょう (Issho ni machimashō, let’s wait together.)
Causative and Passive Voices
Make someone wait: 待たせる (mataseru, causative). Be made to wait: 待たされる (mataserareru, causative-passive). These advanced forms appear in nuanced sentences.
Examples:
- 子供を待たせた (Kodomo o mataseta, I made the child wait.)
- 長く待たされた (Nagaku matasareta, I was made to wait a long time.)
Conditional and Progressive Tenses
Conditionals: 待ったら (mattara, if waited); 待たなければ (matanakereba, unless wait). Progressives build on te-form: 待っていた (matte ita, was waiting).
| Conditional | Plain | Polite |
|---|---|---|
| -tara | 待ったら (mattara) | 待ちましたら (machimashitara) |
| -ba | 待てば (mateba) | 待ちますなら (machimasu nara) |
Imperative: Commands to Wait
Casual command: 待て (mate). Polite: 待ってください (matte kudasai). Negative: 待つな (matsu na), don’t wait.
- ここで待て！(Koko de mate! Wait here!)
Common Phrases and Usage Tips
Incorporate matsu into daily Japanese:
- 待ってて (Matte te, wait a sec – casual contraction).
- 待ちぼうけ (Machibōke, waiting in vain).
- お待ちください (Omatase kudasai, please hold on – service context).
Practice tip: Pair with particles like を (direct object) or で (location): 駅で待つ (Eki de matsu, wait at the station).
