यह दवा की गोली है।

Here is the sentence broken down:

• यह = this
• दवा = medicine
• की = of / a possessive marker here
• गोली = pill / tablet
• है = is

So the structure is literally something like:

This medicine-of pill is.

Natural English is: This is a medicine pill/tablet or This is a pill of medicine, depending on context.

Hindi possessive markers change to agree with the noun that comes after them.

The three common forms are:

• का for masculine singular
• की for feminine singular
• के for masculine plural (and some other cases)

In दवा की गोली, the possessed noun is गोली, and गोली is feminine singular. So the correct form is की.

That is why it is:

• दवा की गोली = medicine pill

not:

• दवा का गोली ❌
• दवा के गोली ❌

In Hindi, every noun has grammatical gender, even if it is not biologically male or female.

गोली is a feminine noun. One clue is that many nouns ending in -ी are feminine, though this is not a perfect rule.

Because गोली is feminine, words that agree with it use feminine forms, such as:

• दवा की गोली

If the noun were masculine, you might see का instead.

This is a very common Hindi pattern:

[noun] + का/की/के + [noun]

It often means something like:

• the [second noun] of [first noun]
• or more naturally in English, a [second noun] related to [first noun]

So:

• दवा = medicine
• गोली = pill/tablet

Together, दवा की गोली means a medicine pill/tablet, basically a pill that is medicine or a medicinal tablet.

English often uses noun-noun combinations, but Hindi often links them with का/की/के.

Hindi usually puts the verb at the end of the sentence.

So while English says:

• This is a medicine pill.

Hindi says:

• This medicine pill is.

That is normal Hindi word order. In simple sentences with to be, है often comes last.

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

So यह दवा की गोली है। can mean:

• This is a medicine pill
• This is the medicine pill

The exact meaning depends on context.

If you really want to make a/an more explicit, Hindi sometimes uses एक:

• यह दवा की एक गोली है। = This is one pill of the medicine / This is a medicine pill

But often एक is not necessary.

Here यह means this.

In careful grammar descriptions, it is often transliterated as yah, but in actual speech it is very commonly pronounced more like yeh.

So learners often hear:

• यह → yeh

That is normal.

Also, यह can sometimes correspond to this, he, she, or it depending on context, but in this sentence it clearly means this.

This is a very common learner question.

Traditionally:

• यह = this / he / she / it (singular, near the speaker)
• ये = these / they (plural, near the speaker)

But in everyday spoken Hindi, many speakers also use ये for singular this in conversation.

So you may hear both:

• यह दवा की गोली है।
• ये dवा की गोली है। (colloquial speech)

For learners, यह is the standard textbook singular form.

गोली most commonly means:

• pill
• tablet

But depending on context, it can also mean:

• bullet
• small round pellet/object

So context matters a lot.

In दवा की गोली, the word दवा makes it clear that this is a medicine pill/tablet, not a bullet.

Yes, but the emphasis changes.

• यह दवा की गोली है। = This is a medicine pill.
• यह गोली दवा की है। = This pill is of the medicine / This pill belongs to the medicine

The second version sounds more contrastive or context-dependent, as if you are distinguishing this pill from something else.

So the original sentence is the more natural choice if you simply want to identify the object.

A simple pronunciation guide is:

yeh da-vaa kee go-lee hai

More smoothly:

yeh dava ki goli hai

A few notes:

• दवा sounds like da-vaa
• की has a long ee sound
• गोली has a long o and long ee
• है is often pronounced roughly like hai or sometimes a bit like heh depending on accent and speed

Yes. In many situations, both are acceptable.

• pill is common everyday English
• tablet is also very common, especially in medical or pharmacy contexts

So दवा की गोली may be understood as either medicine pill or medicine tablet, depending on the situation.

Unlike some other Hindi words, यह does not change form here based on whether the noun is masculine or feminine.

So you can have:

• यह लड़का है। = This is a boy.
• यह लड़की है। = This is a girl.
• यह दवा की गोली है। = This is a medicine pill.

The gender difference shows up elsewhere in Hindi, but not in यह itself in this kind of sentence.
