Questions & Answers about neko no me wa ookii desu.

Why is there の between 猫 and 目?

The particle の links two nouns in a possessive or descriptive way.

• 猫の目 literally means “the eye(s) of a cat” or “cat’s eye(s).”
• Pattern: A の B → “B of A.”
  
  • Examples: 私の本 (my book), 日本の文化 (Japanese culture).

Why do we use は after 目 instead of another particle?

は is the topic marker. It tells the listener what we’re talking about before commenting on it.

• 猫の目は… = “As for the cat’s eyes…”
• After the topic, you give information (大きいです).
• If you used が here, you’d be marking the subject rather than setting it up as the topic.

Could we use が instead of は (i.e. 猫の目が大きいです), and what’s the nuance?

Yes, 猫の目が大きいです is grammatically correct.

• Using が marks “cat’s eyes” as the subject and often introduces new or emphasized information.
• Using は treats “cat’s eyes” as already known or as the topic of conversation.
• Nuance: は often implies contrast or shared knowledge; が is more neutral or used to answer questions like “What’s big?” → “猫の目が大きいです.”
