Questions & Answers about मरीज को बुखार है।

Why is को used after मरीज here?

In this sentence, को marks the person who is experiencing the condition. Hindi often uses this pattern for physical states, feelings, and sensations.

So:

• मरीज = patient
• मरीज को = to the patient / the patient has
• बुखार है = there is fever / has a fever

A very natural way to think of this structure is:

• X को Y है = X has Y or Y is affecting X

You will see the same pattern in sentences like:

• मुझे भूख है। = I am hungry.
• उसे दर्द है। = He/She has pain.
• बच्चे को ठंड है। = The child is cold.

So को is not random here—it is part of a very common Hindi pattern.

Why doesn’t Hindi just say something like मरीज बुखार है?

Because that would be ungrammatical in standard Hindi. Hindi usually does not express having in the same direct way English does.

English says:

• The patient has a fever.

Hindi often expresses this more like:

• To the patient, fever exists.

That is why को is needed. The basic structure is:

• [person] को [condition/thing] है

So:

• मरीज को बुखार है। = The patient has a fever.
