1. "ಬೇಕು" (bēku) - This is the most common way to express "want" in Kannada. It literally translates to "need" but is often used to express desire or wish.
Examples:
* ನನಗೆ ಅನ್ನ ಬೇಕು. (nange anna bēku) - I want rice.
* ನಾನು ಹೊಸ ಕಾರು ಬೇಕು. (nānuhosa kāru bēku) - I want a new car.
* ನಿನಗೆ ಏನು ಬೇಕು? (ninage ēnu bēku?) - What do you want?
2. "ಆಸೆ" (āse) - This word implies a stronger desire, more like a "craving" or "longing" for something.
Examples:
* ನನಗೆ ಸಿಹಿ ಆಸೆ. (nange sihi āse) - I have a craving for sweets.
* ನೀವು ಆಕೆಯ ಮೇಲೆ ಆಸೆ ಇಟ್ಟಿದ್ದೀರಿ ಎಂದು ನನಗೆ ಗೊತ್ತು. (nīvu ākeya mēle āse iṭṭiddīri endu nange gottu) - I know you have a longing for her.
The choice between "ಬೇಕು" and "ಆಸೆ" depends on the intensity of the desire being expressed.
