N3 Grammar Master Review: Bridge the Gap to Fluency

Welcome to your N3 Grammar Master Review! Passing the JLPT N3 is a major milestone. It marks your transition from basic survival Japanese to functional, expressive fluency.

Today, we will dissect three high-yield grammar points that frequently appear on the exam and are essential for natural conversation. Let's master their structures, nuances, and hidden traps.

---

This grammar point is used to express doing an action while a certain state persists, or before that state changes.

Grammar Structure

• Verb (Dictionary / ~ている / ~ない) + うちに
• Noun + のうちに
• い-Adjective + うちに
• な-Adjective + なうちに

The Nuance

There are two primary uses:

1. While: Doing something while a temporary state exists (before it's too late).
2. Before: Doing something before a change occurs (often paired with a negative verb).

Examples

• 日本にいるうちに、京都へ行きたいです。
  • Nihon ni iru uchi ni, Kyōto e ikitai desu.
  • While I am in Japan, I want to go to Kyoto. (Before I leave)
  日本京都行
• スープが温かいうちに食べてください。
  • Sūpu ga atakakai uchi ni tabete kudasai.
  • Please eat the soup while it is still hot. (Before it gets cold)
  温食
• 暗くならないうちに、帰りましょう。
  • Kuraku naranai uchi ni, kaerimashō.
  • Let’s go home before it gets dark.
  暗帰

💡 Tutor’s Tip: Do not confuse 〜うちに with 〜間に (aida ni). While both mean "while," 〜うちに carries a sense of urgency—if you don't act now, the opportunity will pass!間

This pattern is used to express a strong, logical denial. Based on facts or objective reasoning, you believe something is absolutely impossible.

Grammar Structure

• Verb / い-Adjective (Plain Form) + わけがない
• な-Adjective + な / である + わけがない
• Noun + の / である + わけがない

Examples

• あんなに優しい彼が、嘘をつくわけがない。
  • Anna ni yasashii kare ga, uso o tsuku wake ga nai.
  • There is no way that he, who is so kind, would lie.
  優彼嘘
• こんなに難しい問題、小学生に解けるわけがない。
  • Konna ni muzukashii mondai, shōgakusei ni tokeru wake ga nai.
  • There is no way an elementary school student can solve such a difficult problem.
  難問題小学生

💡 Tutor’s Tip: In casual speech, わけがない often shortens to 〜わけない (wake nai) or 〜はずがない (hazu ga nai). They are virtually interchangeable, but wake ga nai sounds slightly more argumentative.

---

When attached to the stem of a verb, 〜切る (transitive) or 〜切れる (potential/intransitive) indicates that an action is finished thoroughly, or done to its absolute limit.切

Grammar Structure

• Verb (ます-stem) + 切る / 切れる切

Examples

• 彼はマラソンを最後まで走り切った。
  • Kare wa marason o saigo made hashirikitta.
  • He ran the marathon all the way to the end. (He finished completely)
  彼最後走切
• こんなにたくさんの料理は、一人では食べきれません。
  • Konna ni takusan no ryōri wa, hitori de wa tabekiremasen.
  • I cannot finish eating this much food by myself.
  料理一人食

💡 Tutor’s Tip: This suffix also expresses strong conviction. For example, 言い切る (iikiru) means "to declare/assert confidently," and 信じ切る (shinjikiru) means "to believe in someone completely without a shred of doubt."言切信

Translate this sentence using today's grammar:
"Before it rains, let's finish washing the clothes."

(Answer: 雨が降らないうちに、洗濯を終え切ってしまおう / 洗濯を終わらせてしまおう。)雨降洗濯終切
