मैं मेज़ से कागज़ ले रही हूँ।

Hindi often builds the present progressive with:

• the verb stem
• रहा / रही / रहे
• a form of होना (to be)

So here:

• ले = the stem used from लेना (to take)
• रही = progressive marker, agreeing with the speaker
• हूँ = am

So ले रही हूँ means am taking.

लेना is the dictionary form, meaning to take.

In a real sentence like this one, Hindi does not use the infinitive लेना. Instead, it uses the verb in a form that can combine with aspect and auxiliary verbs.

So:

• लेना = to take
• ले रही हूँ = am taking

This is normal Hindi verb grammar.

Yes.

In this sentence, रही shows that the speaker is feminine singular.

So:

• मैं मेज़ से कागज़ ले रही हूँ। = said by a female speaker
• मैं मेज़ से कागज़ ले रहा हूँ। = said by a male speaker

If the subject were plural, or in some respectful uses, you could get रहे instead.

से here means from or off.

So:

• मेज़ से = from the table / off the table

That fits the idea of taking a paper away from the table.

This is a good example of a Hindi postposition. English uses prepositions before the noun, but Hindi usually uses postpositions after the noun:

• English: from the table
• Hindi: मेज़ से

Because पर and से do different jobs.

• पर = on
• से = from

So:

• मेज़ पर कागज़ = paper on the table
• मेज़ से कागज़ ले रही हूँ = am taking paper from/off the table

If you used पर, you would be describing location, not the source of the movement.

Hindi normally prefers Subject–Object–Verb order.

So the structure here is roughly:

• मैं = subject
• मेज़ से = from the table
• कागज़ = object
• ले रही हूँ = verb phrase

English usually puts the verb earlier:

• I am taking paper from the table

Hindi usually puts the main verb phrase at the end:

• मैं मेज़ से कागज़ ले रही हूँ।

That is completely normal.

Because in Hindi, the auxiliary verb usually comes at the end of the clause, together with the rest of the verb phrase.

So in ले रही हूँ:

• ले = take
• रही = progressive marker
• हूँ = am

Hindi likes to keep that whole verbal part at the end.

Because this sentence is in the present progressive / imperfective, and Hindi normally does not use ने with the subject in this kind of clause.

So:

• मैं मेज़ से कागज़ ले रही हूँ। = no ने

But in a perfective sentence, you often do get ने:

• मैंने मेज़ से कागज़ लिया। = I took the paper from the table.

This is an important pattern in Hindi:

• imperfective/progressive: usually no ने
• perfective transitive clauses: often ने

Hindi does not have articles that work the same way English a/an/the do.

So कागज़ can mean:

• paper
• a paper
• the paper

And मेज़ can mean:

• table
• the table

The exact meaning usually comes from context.

If Hindi wants to be more specific, it can use other words, for example:

• एक कागज़ = a paper / one paper
• वह कागज़ = that paper

In this sentence, the progressive form agrees with the subject, not the object.

That is why रही matches मैं as a feminine singular speaker.

So even though कागज़ is masculine, the sentence still has रही because the subject is feminine.

This is why:

• female speaker: ले रही हूँ
• male speaker: ले रहा हूँ

This is a very common question.

• ले रही हूँ = am taking right now, in progress
• लेती हूँ = take, do take, or usually take, depending on context

So:

• मैं मेज़ से कागज़ ले रही हूँ। = I am taking paper from the table right now.
• मैं मेज़ से कागज़ लेती हूँ। = I take paper from the table / I usually take paper from the table.

So रही हूँ makes the action feel ongoing.

Yes, often it can.

Because हूँ already shows first person singular, and रही shows feminine singular, Hindi can often leave out मैं if the subject is obvious from context.

So both can work:

• मैं मेज़ से कागज़ ले रही हूँ।
• मेज़ से कागज़ ले रही हूँ।

The version with मैं is a little more explicit.

In this sentence, it will usually be understood as singular unless context says otherwise.

But कागज़ can sometimes look the same in singular and plural contexts, so Hindi often relies on context, numbers, or other words to make it clearer.

For example:

• एक कागज़ = one paper
• दो कागज़ = two papers

So in your sentence, the most natural reading is probably paper / a paper or the paper, depending on context.
