क्या तुम टीवी देख रहे हो?

At the beginning of a sentence, क्या often acts as a yes/no question marker. In this sentence, it does not mean what.

So:

• क्या तुम टीवी देख रहे हो? = Are you watching TV?

But compare:

• तुम क्या देख रहे हो? = What are you watching?

So the position of क्या matters a lot.

Hindi usually follows subject–object–verb order, while English usually uses subject–verb–object.

So this sentence is arranged like:

• क्या = yes/no question marker
• तुम = you
• टीवी = TV
• देख रहे ho = are watching

A very literal layout would be something like Are-you TV watching?, not normal English order. This is completely natural in Hindi.

तुम is the familiar or informal way to say you. It is common with friends, siblings, classmates, children, or people you know well.

Hindi has different levels of you:

• तू = very intimate, very informal, sometimes rude depending on context
• तुम = familiar, casual
• आप = polite, respectful

So if you wanted a more polite version of this sentence, you would say:

• क्या आप टीवी देख रहे हैं?

देख रहे हो is the present progressive form, meaning are watching.

It breaks down like this:

• देख = watch / see (verb stem)
• रहे = progressive part
• हो = are

Together, देख रहे हो means are watching when speaking to तुम.

Because the subject is तुम.

With तुम, Hindi uses हो.
With वह or यह, Hindi uses है.
With आप, Hindi uses हैं.

Compare:

• तुम देख रहे हो = you are watching
• वह देख रहा है = he is watching
• आप देख रहे हैं = you are watching (polite)

So हो matches तुम.

This is something many learners notice. With तुम, Hindi typically uses plural-style verb agreement, so a male addressee commonly takes रहे हो, not रहा है.

So:

• तुम देख रहे हो = you are watching (to a male / often general familiar you)
• तू देख रहा है = you are watching (very informal singular)

This is just how the तुम pattern works in standard Hindi.

You would usually say:

• क्या तुम टीवी देख रही हो?

The change is:

• रहे → रही

So:

• रहे = masculine form used here with तुम
• रही = feminine singular

This gender change is very common in Hindi verb forms.

The verb देखना literally means to see / to look at / to watch, depending on context.

In this sentence, because the object is TV, the natural meaning is to watch TV.

So even though the basic verb is broad, context makes the meaning clear.

Yes, very often in conversation you can. Hindi can make a yes/no question just by using question intonation.

So both of these can work:

• क्या तुम टीवी देख रहे हो?
• तुम टीवी देख रहे हो?

The version with क्या is clearer and more textbook-like, so it is very useful for learners.

It is basically a borrowing from English TV, but written in Devanagari as टीवी.

It is pronounced approximately like:

• ṭī-vī

This is very common in Hindi: many modern everyday words come from English but are written in Hindi script.

This is an important distinction.

• देख रहे हो = are watching right now, at this moment
• देखते हो = watch / do watch / usually watch

So:

• क्या तुम टीवी देख रहे हो? = Are you watching TV?
• क्या तुम टीवी देखते हो? = Do you watch TV? / Do you usually watch TV?

The first is progressive, and the second is more habitual.

These two sentences are very different:

• क्या तुम टीवी देख रहे हो? = Are you watching TV?
• तुम क्या देख रहे हो? = What are you watching?

In the first sentence, क्या is a yes/no marker.
In the second sentence, क्या really means what.

This is one of the most useful contrasts to learn early.

A basic answer would be:

• हाँ, मैं टीवी देख रहा हूँ। = Yes, I am watching TV.
• हाँ, मैं टीवी देख रही हूँ। = Yes, I am watching TV. (female speaker)

A negative answer would be:

• नहीं, मैं टीवी नहीं देख रहा हूँ।
• नहीं, मैं टीवी नहीं देख रही हूँ।

Notice that when I speak, the ending changes to match my gender, not the listener’s.
