यह दवा तरल है।

यह means this here.

So यह दवा = this medicine.

A useful note:

• यह = this
• वह = that

In everyday speech, यह is often pronounced more like ये or yeh.

Both are possible, but they mean slightly different things in structure.

• यह दवा तरल है। = This medicine is liquid.
• यह तरल दवा है। = This is liquid medicine.

In your sentence, तरल is describing the state or quality of the medicine, and है makes it a full sentence: is liquid.

So the pattern is:

subject + description + है

Here:

• यह दवा = subject
• तरल = description
• है = is

In Hindi, the verb usually comes at the end of the sentence.

So where English says:

• This medicine is liquid

Hindi says:

• This medicine liquid is
• यह दवा तरल है

This is a very normal Hindi word order.

दवा means medicine or medication.

It is a very common word in Hindi.

Examples:

• यह दवा अच्छी है। = This medicine is good.
• दवा लो। = Take the medicine.

Also, दवा is a feminine noun in Hindi.

तरल means liquid or fluid.

In this sentence, it describes the form of the medicine: it is not a tablet or powder, but a liquid.

Depending on context, Hindi speakers might also use:

• लिक्विड = liquid (borrowed from English, common in speech)
• पानी जैसा = watery / like water
• तरल रूप में = in liquid form

But तरल is perfectly correct.

Good question. Not all Hindi adjectives change form.

Some adjectives do change:

• अच्छा लड़का = good boy
• अच्छी दवा = good medicine

But some adjectives stay the same for masculine and feminine nouns. तरल is one of those adjectives that usually does not change.

So:

• तरल पदार्थ = liquid substance
• तरल दवा = liquid medicine

No change is needed.

Yes. दवा can often be translated as medicine, medication, or sometimes drug, depending on context.

For most learners, medicine is the safest and most natural translation here.

So:

• यह दवा तरल है। = This medicine is liquid.

Hindi does not usually use articles like a, an, or the.

So दवा can mean:

• medicine
• a medicine
• the medicine

The exact meaning depends on context.

In this sentence, यह already makes it specific, so यह दवा naturally means this medicine.

A simple pronunciation guide is:

yeh da-vā ta-ral hai

A slightly more natural spoken version might sound like:

ye da-vā ta-ral hai

Notes:

• यह is often said like yeh or ye
• दवा sounds like davā
• है sounds roughly like hai

Yes, very often.

In careful writing, the word is यह.

But in everyday speech, many speakers say:

• ये दवा तरल है

Even though ये can also mean these, in casual speech it is often used for this too. Standard written Hindi keeps यह for singular.

So as a learner:

• Learn यह as the standard form
• Be ready to hear ये in conversation

Yes, it is grammatical and understandable.

It is a clear way to say that the medicine is in liquid form.

Depending on context, native speakers might also say:

• यह दवा लिक्विड है।
• यह दवा तरल रूप में है।
• यह सिरप है। if it is specifically a syrup

But यह दवा तरल है। is perfectly fine Hindi.

Yes.

If you say:

• यह तरल दवा है।

that means:

• This is liquid medicine.

That structure treats तरल दवा as one noun phrase: liquid medicine.

But your original sentence:

• यह दवा तरल है।

means:

• This medicine is liquid.

So the difference is mainly between:

• describing the type of medicine
• describing the state/form of the medicine

The pattern is:

यह + noun + adjective + है

More generally:

subject + predicate adjective + है

So here:

• यह = this
• दवा = medicine
• तरल = liquid
• है = is

You can build similar sentences easily:

• यह पानी ठंडा है। = This water is cold.
• यह किताब नई है। = This book is new.
• यह कमरा बड़ा है। = This room is big.
