I saw this:


Is this a correct sentence? I got confused with おしえる人. I thought we cannot follow a verb with another noun without nominalizing it with either の or こと. Should this be おしえるの人?

    That's not nominalized.

This is a very important construction called a relative clause.

a person who teaches

The rule is described in detail in this question: Relative clauses distinguishing whom/with which/that

  • I am so sorry I am still confused. I read the link you posted but I have some questions hope you can help. If おしえるひと is a relative clause then what is こと and の for? Are they called nominalizers? When will I know that I need nominalizers on a verb? Because おしえる is a verb and the reason why I thought I need a nominalizer is because I will use おしえる to describe 人 so in a way I use it as an adj. 👈 what is wrong in this line of thinking?

  • Please check what is wrong with my understanding : アンさんは人です - is the main sentence. Since I want to add more info about what kind of person アンさん is I need something that will describe 人. I have the sentence アンさんは勉強をおしえるです (?) and I will add it to 人 so it will be 勉強をおしえる add の to 人 because that is one noun phrase? Should の be added to verb if and only if it is not in a relative sentence?

    @Shiniboi Use a nominalizer when you want to turn a verb into a noun. Use a relative clause when you want to use a verb as an adjective. Don't add の when you use a relative clause. Something like 教えるの人 is always ungrammatical in Japanese.

In general, it is safe to use a verb directly before a noun. There is no modification needed. If you add の after a verb, you turn it into a noun. Two nouns cannot be connected directly, there has to be a の inbetween, as in 私の本.
