बतख पानी में है।

A word-by-word breakdown is:

• बतख = duck
• पानी = water
• में = in
• है = is

So Hindi is literally structured more like:

• duck water in is

Natural English rearranges that as The duck is in the water or A duck is in the water.

Hindi usually follows Subject–Object/Complement–Verb order, so the verb often comes at the end.

In this sentence:

• बतख = subject
• पानी में = location phrase, in the water
• है = verb, is

So Hindi puts the sentence together as:

• बतख
  • पानी में
    • है

This is very normal in Hindi. English prefers The duck is in the water, but Hindi prefers Duck water in is.

में is a postposition meaning in, inside, or within, depending on context.

Hindi uses postpositions instead of English-style prepositions.
That means the word comes after the noun, not before it.

So:

• पानी में = in water
• literally: water in

This is one of the biggest structural differences from English.

Hindi usually does not use articles the way English does.

So बतख can mean:

• a duck
• the duck

And पानी can mean:

• water
• the water

The exact meaning depends on context.
So बतख पानी में है। could mean:

• The duck is in the water.
• A duck is in the water.

Both are possible.

बतख is generally treated as a feminine noun in Hindi.

In this particular sentence, you do not really see that clearly, because:

• है does not change for masculine vs. feminine singular
• there is no adjective here that would show agreement

But in other sentences, gender can matter. For example, with participles or adjectives, feminine agreement may become visible.

So for this sentence, it is good to know the gender, but it does not change the form much.

The sign above मे in में is called a chandrabindu. It marks nasalization.

So में is pronounced roughly like:

• mein with a nasal sound

It is not exactly the same as English main or men, but many learners start with something like mayn with a light nasal tone.

So:

• मे = me
• में = mein / in

That nasalization is important because it helps distinguish the word correctly.

A simple learner-friendly pronunciation is:

• ba-takh

More carefully:

• ब = b
• त = a dental t sound, with the tongue closer to the teeth than English t
• ख = kh, an aspirated k sound

That last sound ख is not the English k. It is a k followed by a noticeable puff of air.

So बतख is approximately:

• buh-tukh
• or ba-takh

depending on accent and teaching style.

Yes.

Because Hindi usually does not use a/the, पानी में can be understood as:

• in water
• in the water

Context decides which English translation sounds best.

For example:

• बतख पानी में है।
  could be The duck is in the water.

But in another context, it might simply describe location more generally, like A duck is in water.

Yes, if the subject is plural or if you are using a respectful singular.

For example:

• बतख पानी में है। = The duck is in the water.
• बतखें पानी में हैं। = The ducks are in the water.

Here:

• है = singular is
• हैं = plural are (and also respectful singular in some contexts)

So in your sentence, है is correct because बतख is singular.

Many Hindi nouns take an oblique form before postpositions like में, से, or पर. But some nouns, including पानी, often look the same in the direct and oblique singular.

So:

• पानी = water
• पानी में = in the water

There is no visible change here, but that does not mean postpositions are unimportant. It just means this noun happens not to show a different form in this context.

Yes in informal writing, texting, or notes, people often leave punctuation out.

The symbol । is the traditional Hindi full stop, called the danda. It works like a period in English.

So all of these may appear:

• बतख पानी में है।
• बतख पानी में है
• sometimes even with an English period: बतख पानी में है.

In proper Hindi writing, । is standard.
