ऊन बैग में रखिए।

ऊन means wool. In this sentence, it is the thing being put somewhere.

A useful note: ऊन is generally treated like a mass noun, like wool in English, not like a countable item such as a wool.

बैग is a borrowed word from English bag. Hindi uses many everyday loanwords, especially for modern objects.

It is written in Devanagari as बैग and pronounced roughly like bag, though the exact vowel quality may differ a little from English depending on the speaker.

में means in / inside here.

So:

• बैग = bag
• बैग में = in the bag

Hindi uses postpositions, not prepositions. That means the word equivalent to in comes after the noun, not before it.

So English says:

• in the bag

but Hindi says:

• bag in

Hindi usually prefers Subject–Object–Verb word order, and the verb often comes at the end.

In this sentence, the structure is basically:

• ऊन = object
• बैग में = location
• रखिए = verb

So Hindi naturally says something like:

• Wool bag in put

rather than English Put the wool in the bag.

This is normal Hindi sentence structure.

रखिए is a polite imperative form of the verb रखना, which means to put, to place, or to keep, depending on context.

In this sentence, it means something like:

• put
• place
• keep

Because it is an imperative, the sentence is giving an instruction or request.

The ending -इए in रखिए is a polite/respectful command form.

So रखिए means:

• please put
• put said politely/respectfully

Hindi has different command forms depending on how formal or polite you want to be. For रखना, you might see:

• रख — very direct / very informal
• रखो — informal
• रखिए — polite/respectful

So रखिए is appropriate when speaking respectfully or politely to someone.

Yes. रखिए and रखिये are spelling variants of the same polite imperative form. Both are used and understood.

Many modern textbooks and standard writing prefer रखिए, but you will definitely see रखिये too.

Hindi does not have articles like English a, an, and the.

So a noun like बैग can mean:

• a bag
• the bag

The exact meaning depends on context.

Likewise, ऊन does not need an article either. Hindi often leaves this information to context rather than marking it with a separate word.

Good question. In Hindi, direct objects do not always take को.

In this sentence, ऊन is an inanimate thing and is the direct object of रखिए. Hindi often leaves such objects unmarked.

So:

• ऊन बैग में रखिए = natural

Using को here would usually sound unnecessary or unnatural in ordinary usage.

Very broadly:

• को is often used with people, animate beings, or very specific/directly affected objects
• but many inanimate objects, especially in simple commands like this, appear without को

Yes. Commands in Hindi usually do not need an explicit subject.

So रखिए already implies you:

• (You) put the wool in the bag

If needed, Hindi could add a pronoun like आप, but it is often omitted because the verb form already shows the level of politeness.

Yes. The verb रखना is quite flexible. Depending on context, it can mean:

• put
• place
• keep

In an instruction like this, English might translate it as put the wool in the bag, but keep the wool in the bag could also fit in some situations.

A rough pronunciation guide is:

• ऊन ≈ oon
• बैग ≈ baig / bag
• में ≈ mein with a nasalized vowel
• रखिए ≈ ra-khee-ye

A few pronunciation notes:

• ऊ is a long oo sound.
• ै in बैग is like the vowel in bait, though in real speech it may vary.
• में has nasalization, so the vowel is slightly nasal.
• ख in रखिए is an aspirated k sound, not the English kh of words like khan exactly, but a k with a strong puff of air.

Yes. If you are speaking to a friend, child, or someone you address informally, you could use a less formal imperative.

Examples:

• ऊन बैग में रखो। — informal
• ऊन बैग में रख। — very direct / very informal

The original sentence ऊन बैग में रखिए। is polite and safer for general use.
