पत्रिका लौटाइए।

• पत्रिका = magazine, journal, or sometimes periodical
• लौटाइए = return it / please return it

So the structure is basically:

• पत्रिका = the thing being returned
• लौटाइए = a polite imperative verb form meaning please return

This is a very normal Hindi pattern: object + verb.

Hindi often leaves out the subject when it is obvious from the verb form or the situation.

In लौटाइए, the verb already shows that the speaker is addressing someone politely, so you is understood automatically.

A fuller version could be:

• आप पत्रिका लौटाइए।

But in everyday Hindi, the आप is often omitted unless it is needed for emphasis or clarity.

This is an important difference.

• लौटना = to return / come back oneself
• लौटाना = to return something, to give back

So:

• लौटिए would mean please come back / please return
• लौटाइए means please return it / please give it back

Since पत्रिका is the thing being returned, Hindi uses the verb based on लौटाना, not लौटना.

लौटाइए is a polite or respectful imperative, typically used with आप.

It is appropriate for:

• strangers
• customers
• teachers
• older people
• formal situations
• polite requests in general

Rough comparison:

• लौटा = very informal
• लौटाओ = informal
• लौटाइए = polite/respectful

So this sentence sounds like a polite instruction or request: Please return the magazine.

Grammatically, it is an imperative, so it is technically a command form. But in actual use, लौटाइए often sounds like a polite request rather than a harsh command.

Depending on tone and context, it could mean:

• Please return the magazine
• Return the magazine, please

If the speaker wants to sound even more explicitly polite, they might add कृपया:

• कृपया पत्रिका लौटाइए।

But कृपया is not required. The verb form itself is already polite.

Because पत्रिका is a direct object, and in Hindi direct objects are often used without को, especially when they are inanimate things like books, magazines, letters, etc.

So:

• पत्रिका लौटाइए। = completely natural

You may sometimes see को with direct objects, especially for emphasis, specificity, or certain styles, but here it is not necessary.

For a learner, the simplest rule is:

• inanimate direct objects often appear with no marker
• animate or definite objects more often take को

No, not in this sentence.

Even though पत्रिका is a feminine noun, the imperative form लौटाइए does not change to match its gender.

That is because this verb form is based on:

• the verb itself
• the person being addressed
• the level of politeness

It is not agreeing with पत्रिका here.

So you would still say:

• किताब लौटाइए।
• पत्रिका लौटाइए।
• कागज़ लौटाइए।

The imperative stays the same.

Hindi normally prefers Subject–Object–Verb order, so putting पत्रिका before लौटाइए is the expected order.

That means:

• पत्रिका लौटाइए। = normal and natural

Hindi usually puts the main verb at the end of the clause. So an English speaker should get used to seeing the object before the verb.

You could add other words before the verb too, for example:

• पत्रिका मुझे लौटाइए। = Return the magazine to me.
• पत्रिका अभी लौटाइए। = Return the magazine now.

The verb still tends to stay at the end.

A helpful pronunciation guide is:

• पत्रिका ≈ pa-tri-kaa
• लौटाइए ≈ lau-taa-ee-ye

A slightly more careful transliteration would be:

• patrikā lauṭāiye

A few pronunciation notes:

• ट in लौटाइए is a retroflex t, made with the tongue curled back slightly
• लौ sounds roughly like lau in loud, but not exactly the same
• इए at the end sounds like ee-ye

Yes. Both spellings are commonly seen:

• लौटाइए
• लौटाइये

They represent the same polite imperative form in modern usage. The shorter spelling लौटाइए is often preferred in standard modern writing, but लौटाइये is also very common and widely understood.

So if you encounter either one, treat them as the same form here.
