Before Doing X (Mae ni)
mae ni, even if the story is in the past.
Grammar Rule in 30 Seconds
Use the dictionary form of a verb + 前に (mae ni) to describe an action that happens before another action.
- Always use the dictionary form (plain form) before 前に: {食べる|たべる}前に (Before eating).
- For nouns, insert の (no) between the noun and 前に: {食事|しょくじ}の前に (Before the meal).
- The main action follows the 前に clause: {寝る|ねる}前に{本|ほん}を読みます (I read a book before sleeping).
Overview
In Japanese, establishing a clear sequence of events is fundamental to communication. The grammatical pattern 前に (mae ni) is one of the most essential tools for this purpose. It functions as a temporal anchor, allowing you to define a reference event and then state what action precedes it.
Whether you are describing your daily routine, giving instructions, or recounting a past experience, 前に provides the structure to say "Before doing X...".
At its core, 前 (mae) is a noun signifying "front" or "before." The particle に (ni) marks a point in time. When you combine a verb or noun phrase with 前に, you create a subordinate clause that specifies the temporal landmark. The structure might feel inverted to an English speaker.
While English sentences often follow chronological order ("I will study before I watch the movie"), Japanese establishes the reference point first: "Movie-watching before, I will study." This "modifier-first" logic is a cornerstone of the Japanese language, where descriptive information almost always precedes the thing it describes.
Understanding 前に is not just about learning a single grammar point; it is about internalizing how Japanese constructs timelines in sentences. It is a versatile and heavily used pattern that, once mastered, will significantly improve the clarity and naturalness of your speech and writing, moving you beyond simple, disconnected sentences into more complex and descriptive expressions.
How This Grammar Works
前に is understanding the relationship between chronological order (what happens in real life) and sentence order (how you say it). Japanese prioritizes the main event as a reference point and then states the preceding action.- 1Action B happens first. (e.g., You wash your hands.)
- 2Action A happens second. (e.g., You eat a meal.)
前に, and then state the first event (Action B).[Action A] + 前に、 [Action B]。食べる前に、手を洗う。- (Eating before, wash hands.)
- Translation: Before eating, I wash my hands.
[Action A] + 前に part as a single unit: a temporal clause. This entire clause acts as an adverb, telling us when Action B takes place. The 前 (mae) in this construction is treated as a noun.寝る前 (neru mae) is literally "the before of sleeping." This is why the rules for connecting words to 前に are the same as the rules for modifying nouns.前に follows a separate, consistent rule, which is a common point of confusion for learners and will be addressed in detail.Formation Pattern
前に depends on its word type. The rules are consistent and parallel the way nouns are modified in Japanese.
前に
前に |
前に is ALWAYS in the dictionary form, even if the overall sentence is past tense or polite. The sentence's tense and politeness level are determined by the final verb.
出かける 前に、窓を閉めます。
出かける 前に、窓を閉める。
日本へ来る 前に、日本語を勉強しました。
日本へ来る 前に、日本語を勉強した。
前に
前 using the possessive particle の.
の + 前に |
の + Noun pattern, as 前 is a noun. Think of it as "the before of the event."
食事の 前に、この薬を飲んでください。`
会議の 前に、資料を確認しておきましょう。`
卒業の 前に、友達と旅行に行きたいです。`
する (e.g., 勉強, 仕事), you may hear the の dropped in casual speech (勉強前に). While common, this is grammatically informal. For correct and clear Japanese, especially in writing, always include the の particle.
前に
前に with a specific duration or quantity of time, it functions like the English word "ago."
前に |
の particle is not used. The time expression directly modifies 前に.
三年 前に、東京に引っ越しました。`
十分 前に、彼はもう帰りましたよ。`
ついさっき 前に、田中さんから電話がありました。`
When To Use It
前に is a flexible pattern used in various contexts to establish a sequence where a preparatory or preceding action is highlighted.毎晩、寝る前に、簡単なストレッチをします。`
朝ご飯を食べる前に、シャワーを浴びるようにしています。`
前に to emphasize the work or steps required before a main event can occur. It highlights the importance of being ready.プレゼンテーションの前に、何度も練習しました。`
飛行機に乗る前に、必ずパスポートの有効期限を確認してください。`
[Event] の前に structure is perfect for clearly stating deadlines. It establishes a firm boundary by which an action must be completed.レポートは来週の月曜日の前に提出が必要です。`
午後三時の前に、この作業を終らせないと…。`
前に is indispensable for arranging events on a timeline for your listener. It helps structure your narrative logically.結婚する前に、妻と二年同棲していました。`
この会社に入る前に、ITの専門学校に通っていました。`
Common Mistakes
前に is straightforward, learners frequently make a few predictable errors. Understanding the logic behind these mistakes is key to avoiding them.前に with the tense of the final verb. This is incorrect. The verb modifying 前 is always in the dictionary form.- Incorrect:
映画を見た前に、夕食を食べた。 (mita mae ni) - Correct:
映画を見る前に、夕食を食べた。 (miru mae ni)
映画を見る is a relative clause that modifies the noun 前. In Japanese grammar, when a relative clause describes an action that has not yet occurred relative to the main action of the sentence, the dictionary form is used. Since eating dinner happens before watching the movie, the movie-watching is still in the "future" from the perspective of the timeline you're creating. The only part of the sentence that reflects the real-world time of the speaker is the final verb (食べた).の Particle with Nounsの particle dropped between a noun and 前に. However, this is grammatically informal.- Colloquial/Informal:
テスト前に緊張する。 (tesuto mae ni) - Correct (Formal/Written):
テストの前に緊張する。 (tesuto no mae ni)
テスト and 前 are both nouns. The standard rule for connecting two nouns is to use the の particle. Omitting it is a common spoken shortcut, similar to dropping particles in other contexts. As a learner, your default should always be to include the の to ensure your Japanese is correct and clear. This is especially true for exams and formal writing.前に with ～てから (te kara)～前に (mae ni) | Looks backward from a future event. | An action that must happen first as a precondition or preparation. | 寝る 前に` 歯を磨く。 (Before sleeping, I brush my teeth.) |～てから (te kara) | Looks forward from a completed event. | The chronological order of steps. | 歯を磨いて から` 寝る。 (After brushing my teeth, I sleep.) |前に when the second event is an important deadline or anchor point. The focus is on the preparation. Use てから when you are simply listing events in the order they occur. The focus is on the flow. They describe the same reality but emphasize different parts of the sequence.Real Conversations
Textbook examples are clean, but 前に is used constantly in natural, everyday speech and writing. Here is how it appears in different contexts.
Scenario 1
> Yuki: 今日の飲み会、8時からだよね？ 間に合いそう？
> (Tonight's get-together is from 8, right? Think you can make it on time?)
>
> Kenji: ごめん、ちょっと仕事が長引いてるんだ。でも、会社を出る 前に 連絡するね！
> (Sorry, work is running a bit long. But I'll message you before I leave the office!)
Context Note: Kenji uses 前に to set an expectation. The action of him messaging is promised to happen before* the anchor event of him leaving work.
Scenario 2
> Subject: 【ご確認】来週のクライアント訪問について
> (For Your Confirmation: Regarding next week's client visit)
>
> 佐藤部長、
> お疲れ様です。
> 来週の水曜日のクライアント訪問の 前に、一度簡単な打ち合わせのお時間をいただくことは可能でしょうか。`
> よろしくお願いいたします。
> 鈴木
>
> (Dear Manager Sato,
> Thank you for your hard work.
> Before the client visit next Wednesday, would it be possible to have a brief meeting at some point?
> Thank you for your consideration.
> Suzuki)
Context Note: Here, 訪問の前に (houmon no mae ni) clearly and politely establishes the deadline for the requested meeting. The meeting must happen before* the visit.
Scenario 3
> Lisa: わー、そのセーター、すごくきれい！ 自分で編んだの？
> (Wow, that sweater is beautiful! Did you knit it yourself?)
>
> Haruka: うん、ありがとう！ 子供が生まれる 前に、時間があったから作ってみたんだ。`
> (Yeah, thanks! I tried making it before my child was born, back when I had time.)
Context Note:* Haruka uses 生まれる前に to define a specific period in her life. It frames her story and provides a clear "before and after" context for when she had the free time to pursue this hobby.
Quick FAQ
前に?No, 前に itself does not have a politeness level. The overall politeness of your sentence is controlled by the final verb. To make a sentence more polite, you change the ending from a plain form (like する) to a polite form (like します).
- Casual:
寝る前に、電話する。 - Polite:
寝る前に、電話します。
前に for "before" and "ago"?Context is everything. When 前に follows a verb or noun + の, it means "before (an event)." When it follows a specific time duration (like 三日 or 二時間), it means "ago."
- Before:
試験の前に(before the test) - Ago:
三日前に(three days ago)
前に (mae ni) and 以前に (izen ni)?Both can mean "before," but they have different nuances. 前に is for specific, sequenced events or points in time. 以前に is more formal and often refers to a more general, undefined past, translating better to "previously" or "in the past."
日本へ来る前に、一度旅行で来たことがあります。 (Before this specific time coming to Japan, I came once on a trip.)以前、東京に住んでいました。(I lived in Tokyo previously / in the past.)
前に with adjectives?It's not common, as 前に typically sequences actions or events. However, you can use it with adjectives that describe a state change by using the verb なる (naru - to become).
料理が冷たくなる前に、早く食べてください。` (Please eat quickly before the food gets cold.)
前に sometimes there and sometimes not?The comma (、 or 読点|とうてん tōten) after 前に is a stylistic choice used to add a pause and improve readability, especially in longer or more complex sentences. It is very common in writing but not strictly required. In short sentences, it's often omitted.
