Questions & Answers about मैं जल्दी आऊँगी, और तुम देर नहीं करोगी।

Why do both verbs end in -गी?

Because both verbs are in the future tense and both agree with a female subject.

• आऊँगी = I will come (said by a female speaker)
• करोगी = you will do / you will be (said to a female तुम)

In Hindi, future forms often show gender:

• मैं आऊँगा = I will come (male speaker)
• मैं आऊँगी = I will come (female speaker)

And with तुम:

• तुम करोगे = you will do (to a male or mixed group, in many contexts)
• तुम करोगी = you will do (to a female)

So the sentence suggests:

• the speaker is female
• the person being addressed is female

Why is it मैं आऊँगी and not just आऊँगी?

Hindi often allows the subject pronoun to be dropped if it is already clear from context.

So both of these are possible:

• मैं जल्दी आऊँगी।
• जल्दी आऊँगी।

The first is more explicit: I will come early.
The second can sound more natural in conversation if it is obvious who is speaking.

Learners often see pronouns more often in teaching sentences because they make the meaning clearer.
