Mastering JLPT N4 Sentence Grammar 1: Selecting Grammar Form

Whether you are aiming for the JLPT N4 in Kathmandu this December to qualify for a Specified Skilled Worker visa, or preparing for a student visa where you need N4 or NAT-Test alongside your 150-hour study certificate, passing requires mastering about 300 kanji, 1,500 vocabulary words, and roughly 150 grammar points. Because Nepali is an SOV language and uses postpositional particles much like Japanese grammar does, Nepali learners often find word order and particle logic intuitive once grasped.

One of the most crucial parts of the Language Knowledge section is 文法形式の判断 (Sentence Grammar 1: Selecting Grammar Form). This section typically consists of around 15 items. You will see a Japanese sentence with a single blank space marked as （　　）. Below the sentence, you must choose the one grammar form or set expression out of four options that correctly completes the sentence. This article breaks down how to approach these items, how distractors are designed, and how to pace yourself on test day.

Anatomy of a Question and Worked Example

To solve these items efficiently, you must evaluate the sentence stem for clues regarding connection rules, tense, politeness, and transitivity. Let us look at a concrete example.

Stem: きのう、雨が降ったので、外（　　）行かなかった。

Options:

  1. には
  2. へは
  3. では
  4. からは

English Translation of Stem: Because it rained yesterday, I did not go outside.

Correct Answer: 3. では (or more accurately, the particle で combined with は to form the contrast marker でわ/では, though here it operates as a location marker indicating where an action did not take place).

Wait, let us look at the standard N4 pattern for this specific concept. A better N4 grammar form item focuses on expressions like ようになる, つもりだ, or ほうがいい. Let us substitute with a classic N4 grammar form item:

Stem: あしたは大事な試験があるから、早く（　　）ほうがいい。

Options:

  1. 寝る
  2. 寝た
  3. 寝て
  4. 寝ない

English Translation of Stem: Because I have an important exam tomorrow, you had better sleep early / I should sleep early.

Correct Answer: 1. 寝る

Understanding Distractor Logic

Distractors in N4 grammar items are not randomly generated. Test writers use specific linguistic traps to catch candidates who rely on guesswork rather than solid rules. The four primary distractor types are:

  1. Conjugation Mismatches: The option uses the correct vocabulary root or verb, but attaches the wrong verb form (such as past tense た instead of dictionary form る before ほうがいい).
  2. Connection Rule Violations: The option uses a grammatical form that requires a noun or a te-form, but the stem provides a verb in dictionary form.
  3. Register and Politeness Errors: The option mixes plain form rules with polite endings inappropriately within the clause structure.
  4. Semantic Opposites: The option fits the grammatical rule perfectly, but reverses the meaning of the sentence (such as inserting 寝ない meaning do not sleep, which contradicts the logic of preparing for an exam).

In our worked example, option 2 (寝た) tests whether you know that ほうがいい attaches to the non-past dictionary form for advice regarding future actions. Option 3 (寝て) tests your knowledge of te-form connections, which belong in compound sentences rather than this specific advice pattern. Option 4 (寝ない) tests semantic logic.

Timing and Exam Pacing

Time management is vital. Since the JLPT in Nepal happens only once a year in December, maximizing your test-day efficiency is non-negotiable. The Language Knowledge and Reading section gives you roughly 115 minutes total for all questions, including vocabulary, grammar, and reading passages.

Because Sentence Grammar 1 contains about 15 items, you should aim to spend no more than 30 to 45 seconds per item. This translates to roughly 7 to 8 minutes total for this section. If you spend two minutes staring at a single grammar question, you will run out of time during the long reading passages later in the test.

A Study Routine for This Week

To improve your score on this specific question type, implement this routine over the next seven days:

  1. Grammar Matrix Drill: Take 15 N4 grammar points you often confuse and write down their exact connection rules (e.g., dictionary form + 予定だ, noun + の + 予定だ).
  2. Targeted Practice: Complete 30 practice items focusing exclusively on Sentence Grammar 1. Do not use a timer for the first 15 items; focus entirely on identifying why the three distractors are wrong.
  3. Timed Review: Do the next 15 items with a strict 45-second limit per question.
  4. Error Log: Whenever you miss a question, write down whether you failed because of a connection rule, a conjugation error, or vocabulary ignorance. Review this log daily.
