Questions & Answers about मुझे दूध चाहिए।
Because चाहिए usually takes the person in the dative form, not the plain subject form.
- मैं = I
- मुझे = to me / me
So the structure is closer to:
- To me, milk is needed/wanted
That is why मैं दूध चाहिए is incorrect, but मुझे दूध चाहिए is correct.
In this sentence, चाहिए means something like is needed, is wanted, or is required.
So मुझे दूध चाहिए can mean:
- I want milk
- I need milk
Which English translation sounds best depends on the situation. In everyday Hindi, चाहिए is very commonly used for expressing a need or a request for something.
