मरीज को बुखार है।

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.

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.

है is the present tense form of होना, meaning to be.

In this sentence, it works like is or there is, depending on how you think about the structure.

So literally, the sentence is something like:

• To the patient, fever is.

But natural English is:

• The patient has a fever.

You will often see है at the end of simple present statements in Hindi.

Because Hindi normally follows SOV word order:

• Subject / experiencer + object or complement + verb

In this sentence:

• मरीज को = the patient
• बुखार = fever
• है = is

So the verb naturally comes last.

This is very common in Hindi:

• राम स्कूल जाता है। = Ram goes to school.
• मुझे पानी चाहिए। = I want water.
• उसे नींद आ रही है। = He/She is feeling sleepy.

मरीज can be used for both masculine and feminine patients. It is a common-gender noun in actual usage.

So you can say:

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

and this could refer to either a male or female patient.

Because the sentence uses है, which does not show masculine/feminine distinction in this form, the gender is not visible here anyway.

If you wanted to make gender explicit, context or additional words would do that.

Hindi usually does not have articles like a, an, and the in the way English does.

So:

• बुखार can mean fever or a fever, depending on context.

In this sentence, English naturally translates it as:

• The patient has a fever.

Even though there is no separate word for a in Hindi.

This is very normal. For example:

• मेरे पास किताब है। = I have a book.
• वह शिक्षक है। = He/She is a teacher.

No article is needed in Hindi.

Yes, in a very literal sense. Since Hindi does not use articles the same way English does, बुखार simply names the condition.

In natural English, though, the best translation is usually:

• The patient has a fever.

Depending on context, it could also be understood as:

• The patient has fever.
• The patient is feverish.

But has a fever is the most standard translation.

Yes, absolutely. This is a very common pattern with pronouns.

Examples:

• मुझे बुखार है। = I have a fever.
• तुम्हें बुखार है। = You have a fever.
• उसे बुखार है। = He/She has a fever.
• हमें बुखार है। = We have a fever.

Notice that the pronouns also take forms used with को:

• मैं → मुझे
• तुम → तुम्हें
• वह → उसे

So this sentence pattern is very useful in everyday speech.

In this kind of sentence, बुखार is usually treated as the name of a condition, not as a countable item.

So Hindi simply says:

• बुखार है = there is fever / has a fever

You do not normally count fevers in this structure. It functions more like a state or illness.

This is similar to other words such as:

• दर्द = pain
• ठंड = cold
• भूख = hunger

Normally, no. That would sound unnatural in standard Hindi.

Since बुखार here is a medical condition, Hindi usually does not use एक with it in this structure.

Natural:

• मरीज को बुखार है।

Unnatural or unnecessary:

• मरीज को एक बुखार है।

Use एक only when you truly mean one and the noun is something naturally countable in that context.

You place नहीं before है.

So:

• मरीज को बुखार नहीं है। = The patient does not have a fever.

This is the normal way to negate such sentences in Hindi.

Pattern:

• X को Y नहीं है = X does not have Y

Examples:

• मुझे दर्द नहीं है। = I do not have pain.
• उसे भूख नहीं है। = He/She is not hungry.
• बच्चे को ठंड नहीं है। = The child is not cold.

A simple yes/no question can be made by adding क्या at the beginning:

• क्या मरीज को बुखार है? = Does the patient have a fever?

In speech, intonation also helps mark it as a question.

You may also hear:

• मरीज को बुखार है?

with questioning intonation, especially in conversation.

It is neutral and very natural. It works well in everyday conversation, medical contexts, and general description.

• मरीज is a standard word for patient
• बुखार is the normal word for fever
• है makes it a plain present statement

So this is a completely normal and useful sentence.

मरीज is pronounced approximately muh-REEZ.

A few pronunciation notes:

• म = m
• री has a long ee sound
• ज here sounds like z in many common pronunciations of this Persian/Urdu-derived word

So a good practical pronunciation is:

• muh-REEZ

And the full sentence is approximately:

• muh-REEZ ko boo-KHAAR hai

Because Hindi and English organize states and conditions differently.

English often uses:

• have + noun → have a fever

Hindi often uses:

• [person] को [condition] है

So instead of copying English structure, it is better to learn the Hindi pattern as its own unit:

• को ... है for experiences and conditions

That way, sentences like these become easier:

• मुझे प्यास है। = I am thirsty.
• उसे डर है। = He/She is afraid.
• मरीज को बुखार है। = The patient has a fever.
