मोमबत्ती अभी जलाओ।

A simple breakdown is:

• मोमबत्ती = candle
• अभी = now / right now
• जलाओ = light it / burn it

So the structure is basically:

candle + now + light

In natural English, that becomes Light the candle now.

जलाओ is the imperative form, so it is used for giving a command, instruction, or request.

It comes from the verb जलाना, which means to light or to cause something to burn.

So:

• जलाना = to light something
• जलाओ = light it / light it now

Because this sentence is telling someone to do something, Hindi uses the imperative form जलाओ.

This is a very common and important question.

• जलना = to burn, to be burning, to be lit
  This is intransitive: the thing itself is burning.
• जलाना = to light something, to burn something
  This is transitive: someone causes something else to burn.

Examples:

• मोमबत्ती जल रही है। = The candle is burning.
• मोमबत्ती जलाओ। = Light the candle.

So in your sentence, जलाओ is used because the speaker wants someone to light the candle, not just describe the candle as already burning.

जलाओ is the imperative form usually used with तुम. It is informal but very common and not automatically rude.

Hindi imperatives often vary by politeness level:

• जला = very informal / used with तू
• जलाओ = informal / familiar / used with तुम
• जलाइए = polite / used with आप

So you could compare:

• मोमबत्ती अभी जला। = very informal
• मोमबत्ती अभी जलाओ। = informal/familiar
• मोमबत्ती अभी जलाइए। = polite

Hindi often does not use को with inanimate direct objects, especially in straightforward command sentences like this one.

So:

• मोमबत्ती जलाओ। = natural
• मोमबत्ती को जलाओ। = possible in some contexts, but less natural here

In everyday Hindi, the object मोमबत्ती can appear directly before the verb without को.

Yes, अभी मोमबत्ती जलाओ is also possible.

Hindi usually puts the verb at the end, but the order of the other words is fairly flexible. Different orders can change emphasis slightly.

• मोमबत्ती अभी जलाओ। = puts early attention on the candle
• अभी मोमबत्ती जलाओ। = puts early attention on now
• मोमबत्ती जलाओ अभी। = possible in speech, but less neutral

So the main rule here is that जलाओ stays at the end, while मोमबत्ती and अभी can move around depending on emphasis.

Not always. अभी can mean different things depending on context.

Common meanings include:

• now / right now
• just now
• at the moment

In an imperative sentence like मोमबत्ती अभी जलाओ, it clearly means now or right now.

But in another sentence, such as:

• वह अभी आया।

it can mean He just came.

So context is very important with अभी.

Yes, मोमबत्ती is a feminine noun.

In this particular sentence, it does not visibly affect the verb form, because जलाओ is an imperative and does not change here for the gender of मोमबत्ती.

But gender does matter in other kinds of sentences. For example:

• मोमबत्ती जल रही है। = The candle is burning.

Here रही shows feminine agreement with मोमबत्ती.

So the noun’s gender is important in Hindi, even if this specific sentence does not show it clearly.

It is pronounced roughly like mom-bat-tee.

A slightly more careful approximation is:

• मोम = mom
• बत्ती = but-tee or bat-tee, depending on accent and how carefully you say it

The त्त in बत्ती shows a doubled t sound, so the middle consonant is a bit stronger than a single त.

A common romanized spelling is mombattī.

That mark is called the danda.

In Devanagari, । works like a full stop or period in English.

So:

• मोमबत्ती अभी जलाओ।

means exactly the same, punctuation-wise, as ending the sentence with . in English.
