Relative Clauses Lesson 7

Mastering the use of relative clauses to describe nouns using complex verb phrases and particles in N3 Japanese.

Context

Describing the World

In Japanese, you don't use 'which' or 'that' to connect sentences. Instead, you modify nouns directly using clauses. Imagine you are trying to describe a specific person or object in a crowded room. You need to be precise.

Think about how you would describe 'the book that I bought yesterday' or 'the person who is talking to the teacher.' In Japanese, the entire description comes before the noun it modifies. This structure allows for very compact and efficient communication.
Explanation

The Modifier Structure

To create a relative clause, you place the modifying sentence directly before the noun. The verb inside the modifier must be in the plain (dictionary) form.

Sentence (Plain Form)+Noun
When the modifier describes a noun that is the subject of the relative clause, we use the particle 'が' (ga) instead of 'は' (wa). This is a crucial rule: inside a relative clause, 'は' is generally avoided unless you are emphasizing a contrast.

Watch out

Never use polite forms (like 'desu' or 'masu') inside the modifying clause. Always use the dictionary form or the past plain form (ta-form).
Examples

Examples in Action

Observe how the verb phrase acts as an adjective for the noun.

昨日(きのう)買った(かった)(ほん)は面白いです。

The book I bought yesterday is interesting.

昨日きのうyesterday買ったかったboughtほんbook

あそこで話している(はなしている)(ひと)は誰ですか。

Who is the person talking over there?

話しているはなしているis talkingひとperson

(わたし)住んでいる(すんでいる)(まち)は静かです。

The town where I live is quiet.

わたしI住んでいるすんでいるlivingまちtown

Which sentence correctly uses the relative clause structure?

  • 昨日買いました本は高いです。
  • 昨日買った本は高いです。
  • 昨日買うた本は高いです。

The modifier must use the plain form (買った) before the noun (本).

Usage

Nuance and Register

Relative clauses are used in both spoken and written Japanese. They are essential for clarity.

Relative Clause vs. Simple Sentence

本を買いました。面白いです。

Two separate sentences; less cohesive.

買った本は面白いです。

One cohesive relative clause; more natural.

Why do we use 'が' instead of 'は' inside the relative clause?

  • To make the sentence sound more polite.
  • To mark the subject of the relative clause specifically.
  • Because 'は' is forbidden in all Japanese sentences.
  • To emphasize the topic of the entire sentence.

In relative clauses, 'が' is used to mark the subject of the modifying verb, as 'は' would create a topic-comment structure that conflicts with the modification.

Deep dive

Advanced Usage

Sometimes, the noun being modified is the object of the relative clause, or even a location/time.

Modifying with Time and Place

You can modify nouns using time or place markers. For example: 'The day I met you' (あなたに会った日) or 'The place where I was born' (私が生まれた場所). The structure remains the same: [Sentence] + [Noun].
Summary

Lesson Recap
