तुम कब से यहाँ रहोगी?

A literal breakdown is:

• तुम = you
• कब से = from when / since when
• यहाँ = here
• रहोगी = will stay / will live (said to a female)

So the sentence is built very straightforwardly: you + from when + here + will stay/live.

The -गी shows that the speaker is addressing a female.

With तुम, the future forms are:

• रहोगे = you will stay/live (to a male)
• रहोगी = you will stay/live (to a female)

Hindi often marks gender in verbs, even when English does not.

The dictionary form is रहना, which means to stay, to live, or to remain, depending on context.

So:

• रहना = to stay / to live
• रहोगी = you will stay / live (female)

कब से asks for the starting point in time.

It literally means from when / since when. In a future sentence like this, it usually means starting when.

This is important because English learners often confuse it with कब तक:

• कब से = from when / since when
• कब तक = until when / how long (up to what point)

No. If you mean until when or how long, you would normally use कब तक, not कब से.

So:

• तुम कब से यहाँ रहोगी? = From when will you be staying here?
• तुम यहाँ कब तक रहोगी? = Until when / how long will you stay here?

That distinction is very common and very important.

तुम can be:

• singular: you in an informal but normal way
• plural: you all

It is less formal than आप, but not as intimate or rude as तू.

In many everyday situations, तुम is used for friends, siblings, classmates, or someone you know reasonably well.

Here are the common variations:

• to a male with तुम: तुम कब से यहाँ रहोगे?
• to a female with आप: आप कब से यहाँ रहेंगी?
• to a male with आप: आप कब से यहाँ रहेंगे?

So both the pronoun and the verb form can change.

No. You do not need क्या here, because कब already makes it a question.

Hindi uses question words like:

• कब = when
• कहाँ = where
• कौन = who
• क्यों = why

So तुम कब से यहाँ रहोगी? is already clearly a question without क्या.

Yes, Hindi word order is somewhat flexible.

This sentence is natural, but you may also hear:

• तुम यहाँ कब से रहोगी?

Both are understandable. Hindi often places the time expression, place expression, and other parts in slightly different positions without changing the basic meaning much.

The verb usually stays near the end.

Yes, very often.

Hindi frequently drops subject pronouns when the meaning is already clear from context. So you could say:

• कब से यहाँ रहोगी?

This still sounds natural if it is already obvious who you refers to.

It can mean either, depending on context.

रहना is a broad verb. It can mean:

• to stay
• to live
• to remain

So रहोगी could be understood as will stay or will live, depending on the situation. Hindi often leaves that slightly open unless the context makes it specific.

Grammatically, रहोगी is a simple future form.

But in English, the most natural translation may sometimes be:

• will stay
• will live
• will be staying

So the Hindi form is simple future, but the best English translation can vary depending on context.

यहाँ is pronounced roughly like yahaan, with a nasal sound at the end.

A more precise transliteration is yahā̃.

The final vowel is nasalized, so it is not just yaha. That nasal sound is an important part of the word.
