क्या तुम मेरा फोन नहीं भूलोगी?

Here, क्या is not the word what.

At the beginning of a sentence, क्या often works as a yes/no question marker. It signals that the whole sentence is a question, similar to how English uses word order like Are you... ? or Will you... ?

So:

• क्या तुम... ? = Will you... ? / Won’t you... ?

If क्या appeared as the thing being asked about, then it could mean what. But in this sentence, it is just marking a yes/no question.

The sentence follows a very common Hindi pattern:

• क्या = question marker
• तुम = you
• मेरा फोन = my phone
• नहीं = not
• भूलोगी = will forget

So the structure is roughly:

Question marker + subject + object + not + verb

Hindi usually puts the main verb near the end, unlike English.

Hindi has different levels of you:

• तू = very intimate / very informal
• तुम = familiar, casual
• आप = respectful / formal

So तुम here means the speaker is talking to someone in a casual or familiar way.

It is not rude by itself, but it is less formal than आप.

Because मेरा agrees with फोन, not with the speaker.

In Hindi, possessives like मेरा / मेरी / मेरे agree with the thing possessed.

Since फोन is usually treated as masculine singular, you get:

• मेरा फोन = my phone

Compare:

• मेरी किताब = my book
• मेरे दोस्त = my friends / my male friend in some contexts depending on structure

So मेरा is chosen because फोन is masculine singular.

Usually, yes.

Many borrowed nouns in Hindi are treated as masculine by default, and फोन is commonly used as a masculine noun. That is why you see:

• मेरा फोन
• यह फोन
• फोन अच्छा है

Loanwords do not always behave perfectly predictably, but फोन as masculine is very normal.

Because फोन is a direct object, and in Hindi, direct objects do not always take को.

With inanimate things like फोन, Hindi often leaves out को:

• मेरा फोन भूलोगी = you will forget my phone

को is more common with:

• people
• animate beings
• strongly specific or affected objects in some contexts

So here, मेरा फोन without को is perfectly normal.

भूलोगी is a future tense form of भूलना (to forget).

The verb stem is:

• भूल- = forget

And -ओगी is the future ending used with tum when speaking to a female.

So:

• तुम भूलोगी = you will forget (said to a female)

Because the person being addressed is understood to be female.

With तुम, the future form changes by gender:

• तुम भूलोगे = you will forget (to a male)
• तुम भूलोगी = you will forget (to a female)

So this sentence is being said to a woman or girl.

In Hindi, नहीं usually comes before the verb or verb phrase it negates.

So:

• नहीं भूलोगी = will not forget

That placement is very normal. Hindi generally does not do negation the way English does with do not / won’t; instead, it uses नहीं before the main verb phrase.

It often implies expectation, concern, or a request for reassurance.

A negative question like this can feel like:

• You won’t forget my phone, right?
• You’re not going to forget my phone, are you?

So it is not just asking for information. It can also suggest that the speaker hopes the answer is no, I won’t forget it.

Yes.

In spoken Hindi, yes/no questions can often be asked just with intonation:

• तुम मेरा फोन नहीं भूलोगी?

This can sound natural in conversation.

Adding क्या makes the question marking more explicit:

• क्या तुम मेरा फोन नहीं भूलोगी?

Both are possible.

Yes. A very common conversational version would be:

• तुम मेरा फोन नहीं भूलोगी न?

The न at the end works a bit like:

• right?
• okay?
• you won’t, will you?

So this version can sound more natural and less stiff in everyday speech.

Negative questions can be tricky for English speakers.

If someone asks:

• क्या तुम मेरा फोन नहीं भूलोगी?

a clear answer would be:

• हाँ, नहीं भूलूँगी। = Yes, I won’t forget it.
• नहीं, भूल जाऊँगी। = No, I will forget it.

Because negative questions can be confusing, Hindi speakers often repeat the verb for clarity instead of relying on हाँ or नहीं alone.

So the safest habit is:

• हाँ, नहीं भूलूँगी।
• नहीं, भूलूँगी। / नहीं, भूल जाऊँगी।

That makes your meaning unmistakable.
