पानी उबालिए।

उबालिए is the polite imperative form of the verb उबालना, which means to boil something.

So this form is used when:

• giving a polite instruction
• making a respectful request
• speaking to आप

It is softer and more respectful than a plain or very familiar command.

The dictionary form is उबालना.

A useful comparison is:

• उबालना = to boil something
• उबलना = to boil / to be boiling

So:

• पानी उबालिए। = boil the water
• पानी उबल रहा है। = the water is boiling

This sentence uses उबालना because someone is causing the water to boil.

Because Hindi usually follows Subject–Object–Verb order.

In this sentence:

• the subject you is understood
• पानी is the object
• उबालिए is the verb

So the natural Hindi order is:

• पानी
  • उबालिए

This is normal Hindi word order for a command like this.

In Hindi, the subject is often left out when it is obvious from the context.

In commands, this is very common. The verb form already shows that the speaker is addressing someone. Since उबालिए is a polite imperative, the listener is understood.

You can say:

• पानी uबालिए।
• आप पानी उबालिए।

Both are correct, but leaving out आप is very common.

Hindi does not always mark direct objects with को.

With inanimate things like पानी, को is usually omitted in simple sentences like this. So:

• पानी उबालिए। = natural
• पानी को उबालिए। = possible in some special contexts, but not the usual everyday phrasing here

So the absence of को is normal.

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

That means पानी can mean:

• water
• the water

The exact meaning depends on context. In a sentence like this, English often uses the water, but Hindi does not need a separate word for the.

Yes. उबालिए is a polite/respectful command form.

It is commonly used:

• with आप
• in respectful speech
• when speaking to someone you do not want to sound blunt with

Compare:

• उबालिए — polite/respectful
• उबालो — informal, used with तुम
• उबाल — very familiar or blunt, used with तू

So उबालिए is usually the safest choice if you want to be polite.

It can be used for both:

• one person respectfully
• more than one person

This is normal in Hindi polite forms. So उबालिए does not by itself tell you whether the speaker is addressing one respected person or several people.

A simple pronunciation guide is:

u-baa-li-ye

More roughly:

• उ = short u
• बा = baa
• लि = li
• ए gives the ending -ye

So the whole word sounds roughly like ubaaliye.

The आ sound in बा is long.

Because Hindi imperatives usually use the main verb by itself.

In other words, उबालिए already means boil / please boil. You do not need है or another helping verb.

This is normal for commands in Hindi:

• बैठिए। = please sit
• सुनिए। = please listen
• पानी उबालिए। = please boil the water

So the sentence is complete as it is.
