Questions & Answers about मैं दरवाज़े पर ताला लगाती हूँ।

Why is लगाती used here? What does it tell me?

लगाती is the feminine singular habitual form of the verb लगाना.

So this sentence suggests that the speaker is female.

• मैं ... लगाती हूँ = I ... lock / I put ...
• If the speaker were male, it would be: मैं दरवाज़े पर ताला लगाता हूँ।

In Hindi, the verb often shows the gender of the speaker in sentences like this.

What does हूँ do at the end of the sentence?

हूँ is the first-person singular form of होना (to be), used as an auxiliary here.

In the pattern:

• लगाती हूँ
• लगाता हूँ

the main verb form (लगाती / लगाता) combines with हूँ to make the habitual present.

• मैं ताला लगाती हूँ = I lock / I do lock / I usually lock

It is not the same as the English continuous I am locking.
