In Japanese, the たい-form lets you express desire — like “want to do” something.
With the verb 見る, for example, you get forms like 見たい (“want to see”) or 見たくない (“don’t want to see”).
These are very common in everyday conversation.
You’ll often hear たい in casual settings — and たいです in polite situations, such as in shops or with people you don’t know well.
This animation shows both casual and polite forms — for both affirmative and negative expressions.
Together, these make a powerful tool for speaking naturally and respectfully in Japanese.
