Questions & Answers about अगर तुम देर से आओगी, तो मैं स्टेशन पर इंतज़ार करूँगी।

Why do आओगी and करूँगी both end in -गी?

Because these are future-tense forms used for a feminine singular subject.

• आओगी = you will come (said to one female person, with तुम)
• करूँगी = I will do / I will (said by a female speaker)

In Hindi, future forms often show gender and number.
For feminine singular, -गी is very common.

So in this sentence:

• तुम ... आओगी tells us the person being addressed is female.
• मैं ... करूँगी tells us the speaker is also female.

If the speaker were male, he would say करूँगा instead of करूँगी.

Why is तुम used with आओगी? Does तुम show gender?

No, तुम itself does not show gender. It simply means you.

The gender is shown by the verb form, not by तुम.

So:

• तुम आओगे = you will come (to a male or mixed group, depending on context)
• तुम आओगी = you will come (to a female)

This is very common in Hindi: pronouns often stay the same, while the verb changes to match gender and number.

If the speaker were male, how would the sentence change?
