* Simple desire: "I want to go to the beach."
* Future intention: "We want to buy a new car next year."
* Request: "Could you please want to open the window?" (This is grammatically incorrect. "Could you please open the window?" is the correct way to phrase a request.)
* With a negative: "I don't want to go to the party."
* With a modal verb: "I might want to go to the movies later."
* In a question: "Do you want to come with me?"
Remember that "want to" is usually followed by a verb in the base form (e.g., "want to go," "want to eat," "want to play").
