NはNです

Meaning

The particle は sets the topic, and the part before です identifies or classifies that topic.

Formation

1. Put the topic before は, then a noun phrase and です: N1はN2です.
2. In this particle use, は is written ha but pronounced wa.

When to use it

Introducing someone or something

States a person's name, occupation, role, or an object's identity.

Classification

Says what category an already established topic belongs to.

Important notes

• A は-topic is not always the grammatical subject; first read it as what the sentence is about.
• Japanese often omits a topic that is already clear from context.

Common mistakes

• Do not pronounce topic は as ha; its reading here is always wa.
• Do not force an English pronoun into every Japanese sentence when the topic is already understood.

Similar grammar

• 〜です〜です is the polite copula itself; NはNです is the full basic pattern with an explicit topic.
• 〜はThe broader は topic also covers contrast and predicates other than nouns.
• 〜がが commonly marks a subject or new information, while は establishes the topic.
