Meaning & Usage
前に (mae ni) means "before" — one action or event happens prior to another. It covers the same ground as English "before": before breakfast, before going out, before a meeting starts. You'll reach for it constantly in everyday Japanese.
The word 前 carries two related meanings: "front" (physical space) and "before" (time). Paired with the particle に, it becomes a temporal marker meaning "before [something happens]." You can attach it to verbs ("before doing X") or to nouns ("before an event"), giving it wide reach across both casual conversation and formal writing.
There is one rule you must get right: the verb immediately before 前に must always be in dictionary form (plain non-past form), no matter what tense the rest of the sentence is in. Even when the overall sentence is past tense — "Before I came to Japan, I studied Japanese" — the verb before 前に stays in dictionary form (来る, not 来た). Tense is determined by the main verb at the end of the sentence, not by the verb in the 前に clause.
前に is register-neutral: it works in a casual chat, a formal business email, or a public notice without any adjustment. For English speakers, there is one more advantage — the word order matches. 食べる前に、手を洗います translates directly as "Before eating, [I] wash [my] hands." No restructuring needed.
Structure & Formation
前に connects to either a verb or a noun, with a slightly different formation for each.
| Pattern | Formation | Example |
|---|---|---|
| Verb pattern | Verb (dictionary form) + 前に | 食べる前に (before eating) |
| Noun pattern | Noun + の + 前に | 食事の前に (before the meal) |
Verb Pattern — All Verb Groups
The verb before 前に must always be in plain dictionary form. This applies to all three verb groups:
- Group 1 (U-verbs): 飲む → 飲む前に (before drinking) | 書く → 書く前に (before writing)
- Group 2 (RU-verbs): 食べる → 食べる前に (before eating) | 起きる → 起きる前に (before waking up)
- Irregular verbs: する → する前に (before doing) | 来る → 来る前に (before coming)
Noun Pattern — Insert の
When 前に follows a noun, insert の between the noun and 前. A few everyday examples:
- 試験 (exam) → 試験の前に (before the exam)
- 食事 (meal) → 食事の前に (before the meal)
- 旅行 (trip) → 旅行の前に (before the trip)
- 授業 (class) → 授業の前に (before class)

Common Mistakes
Mistake 1: Using た-form (Past Form) Before 前に
❌ 食べた前に、手を洗います。
✅ 食べる前に、手を洗います。
The most common mistake with 前に. The verb before it must always be in dictionary form — never た-form, even when the overall sentence is past tense. At the reference point in time, the "before" action hasn't happened yet. It's still a pending, neutral event — not a completed one. That's why た-form doesn't belong here.
Mistake 2: Using ます-form Before 前に
❌ 食べます前に、手を洗います。
✅ 食べる前に、手を洗います。
Beginners often reach for ます-form because it feels safe, but it doesn't belong before 前に. Politeness is controlled by the final verb, not the 前に clause. A plain-form verb followed by a polite ます ending is completely standard — and the only correct structure here.
Mistake 3: Confusing 前に (Before) with 後で (After)
❌ 食べる後で、歯を磨きます。(using dictionary form with 後で)
✅ 食べた後で、歯を磨きます。(After eating, I brush my teeth.)
前に means "before"; 後で (あとで) means "after." Their verb forms are opposite: 前に takes dictionary form, while 後で takes た-form. The logic is consistent — the action before 後で is already done (completed → た-form); the action before 前に hasn't happened yet (not completed → dictionary form). Study them as a pair and the contrast locks in naturally.
Mistake 4: Forgetting の When Connecting Nouns
❌ 試験前に、よく寝てください。
✅ 試験の前に、よく寝てください。(Before the exam, please get plenty of sleep.)
Without の, the phrase sounds clipped or ungrammatical. The の connects the noun to 前に — think of it as possessive: 試験の前に literally reads as "the exam's before." It is always required when a noun precedes 前に.
Mistake 5: Using て-form Before 前に
❌ 食べて前に、手を洗います。
✅ 食べる前に、手を洗います。
The て-form links sequential actions with a sense of flow — do A, then do B. 前に marks a time boundary: something must occur prior to a reference point. They are not interchangeable. Whenever you mean "before doing X," use dictionary form + 前に.
Cultural Notes
前に appears naturally in some of Japan's most familiar daily rituals. At mealtimes, it's standard to say: 食事の前に、いただきます。("Before the meal, [we say] itadakimasu.") The phrase いただきます expresses gratitude — for the food, the cook, and the ingredients themselves. It is a deeply rooted custom, and 前に is the grammar that frames it.
Practical written Japanese — product labels, office signs, public announcements — leans on 前に constantly. Phrases like 使用する前に (before use) and 入室する前に (before entering the room) appear everywhere. Recognizing the pattern helps you navigate real instructions well before your overall vocabulary is strong.
前に also comes up naturally in storytelling. When recounting a first trip to Japan, for instance, it feels completely natural to say: 日本に来る前に、ひらがなを覚えました ("Before coming to Japan, I memorized hiragana"). The pattern gives your narrative a clear chronological spine without extra words.
Japanese business and school culture both prize preparation. Phrases like 会議の前に資料を確認してください ("Before the meeting, please check the materials") are standard in professional settings. Using 前に correctly signals fluency in both the language and the expectations that surround it.

JLPT Tips
On the JLPT N5 exam, 前に most commonly appears in sentence grammar questions where you choose the correct verb form or particle. The most frequently tested point is the verb form before 前に — always dictionary form, never た-form or ます-form. If you remember one rule for the test, make it this one.
A reliable test-taking strategy: when you see 前に in a multiple-choice grammar question, look immediately at what comes directly before it. If the answer choices include both dictionary form (e.g., 食べる) and た-form (e.g., 食べた), the correct answer is always dictionary form. No exceptions for 前に.
Watch for the noun + の + 前に pattern in reading comprehension passages as well. Instructions, schedules, and procedural texts on the JLPT frequently use 前に to describe preparation steps or ordered sequences. Spotting the pattern quickly lets you identify the main point without getting snagged on unfamiliar vocabulary.
On the listening section, 前に comes up often in conversations about daily routines, travel plans, and health habits. A dictionary-form verb immediately before 前に is your signal that the speaker is explaining what they do — or recommend doing — before a certain activity. These topics appear regularly on the N5 listening exam.
Finally, do not confuse 前に with 以前, which means "previously" or "in the past" in a general sense. 以前 is not attached to a specific verb or action the way 前に is. For N5, focus on the two core patterns: verb (dictionary form) + 前に and noun + の + 前に. These cover the vast majority of how 前に appears on the exam and in real life.
