क्या तुम स्कूल जाती हो?

At the beginning of a sentence, क्या often marks a yes/no question.

So:

• क्या तुम स्कूल जाती ho? = Do you go to school?

In this use, क्या does not mean what.
It is just a question marker.

Compare:

• क्या तुम स्कूल जाती हो? = Do you go to school?
• तुम क्या पढ़ती हो? = What do you study/read?

So क्या can mean different things depending on where and how it is used.

तुम means you.

Hindi has different ways to say you, depending on formality and relationship:

• तू = very informal/intimate, sometimes rude in the wrong context
• तुम = informal but common and neutral in many situations
• आप = polite/formal

So तुम is used for someone you know fairly well, someone younger, a friend, sibling, classmate, etc.

Because the person being addressed is female.

In this kind of sentence, the verb form agrees with the gender of the subject:

• to a girl/woman: तुम स्कूल जाती हो
• to a boy/man: तुम स्कूल जाते हो

So:

• जाती = feminine
• जाते = masculine (or mixed/plural in many contexts)

This is one of the first things English speakers notice, because English verbs usually do not change for gender, but Hindi verbs often do.

जाती हो is the habitual present form here, used for something someone generally does or regularly does.

It is built from:

• जा = verb root from जाना (to go)
• जाती = habitual participle, feminine singular
• हो = auxiliary used with तुम

So जाती हो means something like:

• go
• do go
• tend to go
• usually go

In natural English, we simply say Do you go to school?

Hindi does not need a separate helping verb like English do for this sentence.

English often uses do/does to make questions:

• Do you go to school?

Hindi instead uses:

• the question marker क्या
• normal verb forms like जाती हो

So the idea of English do is not translated word-for-word here.

A very literal breakdown would be closer to:

• क्या = question marker
• तुम = you
• स्कूल = school
• जाती हो = go / habitually go

हो is the auxiliary that matches तुम in this structure.

Compare:

• मैं जाती हूँ = I go (female speaker)
• तुम जाती हो = you go
• वह जाती है = she goes
• हम जाते हैं = we go

So हो is the form used with तुम.

A common mistake is to use है instead of हो:

• incorrect: तुम स्कूल जाती है
• correct: तुम स्कूल जाती हो

स्कूल is a very common loanword from English, adapted into Hindi pronunciation and writing.

Hindi often uses borrowed words, especially for modern institutions and everyday objects. So स्कूल is completely normal Hindi usage.

You may also hear विद्यालय, which is a more Sanskrit-based or formal word for school, but in everyday speech स्कूल is much more common.

Because Hindi often uses destinations without a separate word equivalent to English to after जाना.

So:

• मैं स्कूल जाती हूँ = I go to school
• वह दिल्ली जाता है = He goes to Delhi

English needs to, but Hindi usually does not here.

So स्कूल appears directly after तुम with no extra marker.

The most standard order here is:

• क्या तुम स्कूल जाती हो?

But Hindi word order is somewhat flexible, especially in speech, as long as the meaning stays clear.

You may also hear:

• तुम स्कूल जाती हो?

This can also mean Do you go to school?, especially with questioning intonation.

So:

• क्या + sentence = clearly marks a yes/no question
• sentence without क्या
  • rising tone = also possible in conversation

For learners, the safest pattern is:

• क्या + subject + object/place + verb + auxiliary

Yes, often in speech.

You can ask:

• तुम स्कूल जाती हो?

If your voice rises like a question, it can mean the same thing.

However, क्या makes it explicitly a yes/no question and is very useful for learners, so it is good to include it until you get comfortable with Hindi question patterns.

Usually, no. This sentence normally means Do you go to school? or Do you go to school regularly?

Because जाती हो is a habitual form, it usually expresses a general habit or repeated action, not an action happening right now.

If you want Are you going to school? in the sense of right now / currently, Hindi often uses a different structure, such as:

• क्या तुम स्कूल जा रही हो? = Are you going to school? (female)

So:

• जाती हो = habitual / regular
• जा रही हो = ongoing / in progress

You would say:

• क्या तुम स्कूल जाते हो?

Only the gender-marked part changes:

• to a girl/woman: जाती हो
• to a boy/man: जाते हो

Everything else stays the same.

Use आप instead of तुम, and change the verb accordingly:

• क्या आप स्कूल जाते हैं? = Do you go to school? (to a man / politely)
• क्या आप स्कूल जाती हैं? = Do you go to school? (to a woman / politely)

Notice two changes:

• तुम → आप
• हो → हैं

So politeness affects the verb form too.

A simple learner-friendly transliteration is:

• Kyaa tum school jaatii ho?

More closely:

• क्या = kyaa
• तुम = tum
• स्कूल = skool
• जाती = jaa-tee
• हो = ho

A few pronunciation notes:

• क्या is often pronounced like kyaa
• जाती has a long aa sound: jaa
• ती sounds like tee
• हो is a clear ho, not English who

The dictionary form is जाना, which means to go.

From जाना, you get forms like:

• जाता = goes / go (masculine habitual)
• जाती = goes / go (feminine habitual)
• जाते = go (masculine plural or with tum for a male addressee)

So when you look up the verb, look for जाना, not जाती.
