Relative Clauses Lesson 3

Mastering complex noun modification using relative clauses with particles and specific verb forms to describe people and objects in detail.

Context

Identifying People and Objects

In daily life, we often need to describe someone or something by what they are doing or what happened to them. Instead of saying 'the man is wearing a hat,' we say 'the man who is wearing a hat.'

In Japanese, this is achieved by placing the entire descriptive clause before the noun. This allows you to create precise, natural descriptions that sound like a native speaker.
Explanation

Structure of Relative Clauses

To turn a sentence into a modifier, you use the plain form of the verb followed by the noun you are describing.

Verb (Plain Form)+Noun
The verb must be in the plain (dictionary or past) form. The entire clause acts as an adjective for the noun. If the verb is in the present tense, it describes a habitual action or a state; if it is in the past tense, it describes a completed action.

Tip

Remember that you cannot use polite forms like 'masu' inside a relative clause. Always convert to the dictionary form first.
Examples

Examples in Action

Here are common ways to use relative clauses to describe people and things.

あれは(わたし)買った(かった)(ほん)です。

That is the book that I bought.

わたしI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

Which sentence correctly uses a relative clause?

  • 食べる人が好きです。
  • 食べます人が好きです。
  • 食べている人が好きです。

Option 3 is correct because it uses the plain form '食べている' to modify '人'. Option 2 is incorrect because '食べます' is a polite form.

Usage

Nuance and Register

Relative clauses are essential for formal writing and detailed speech. They are neutral in politeness, but the surrounding sentence determines the register.

Relative Clause vs. Simple Sentence

本を買いました。それは面白いです。

Two separate sentences (less fluid).

買った本は面白いです。

One relative clause (more natural/fluid).

Can you use 'masu' form inside a relative clause?

  • Yes, if it is formal.
  • No, never.

Relative clauses must always use plain form verbs regardless of the politeness level of the main sentence.

Deep dive

Advanced Particles

Sometimes you need to include particles inside the relative clause.

Particles inside clauses

When the verb in the relative clause requires a particle like 'ni' or 'de', you keep it inside the clause. For example: '私が住んでいる家' (The house I live in).
Summary
