कपड़ों की टोकरी ऊपर है।

It is a genitive phrase meaning literally basket of clothes.

• कपड़ों = of clothes
• की = genitive marker, like of
• टोकरी = basket

So the whole noun phrase works like the clothes basket or the basket of clothes.

Because कपड़े changes to the oblique plural form कपड़ों before a postposition.

In Hindi, nouns often have:

• a direct form
• an oblique form, used before postpositions

Here, की is a postposition/genitive marker, so कपड़े becomes कपड़ों.

A quick pattern:

• कपड़ा = a cloth / a garment
• कपड़े = clothes
• कपड़ों = of clothes

Because का / की / के agrees with the noun that comes after it, not with कपड़ों.

The noun after it is टोकरी, which is:

• feminine
• singular

So Hindi uses की.

Compare:

• राम का घर = Ram’s house → घर is masculine singular
• राम की किताब = Ram’s book → किताब is feminine singular
• राम के दोस्त = Ram’s friends → दोस्त is plural

So in कपड़ों की टोकरी, की matches टोकरी.

Normally, no. It means a basket for clothes / a basket containing clothes / a clothes basket.

The phrase is understood from context as a relationship of possession or association: the basket of clothes.

If you wanted to say a basket made of cloth, you would usually express that differently, and context would matter a lot. So here, the natural meaning is simply clothes basket.

Because Hindi usually does not use articles like a and the.

Whether something is a basket or the basket is usually understood from context.

So:

• टोकरी can mean a basket or the basket
• कपड़ों की टोकरी ऊपर है can be understood as The clothes basket is upstairs / up there, depending on context

ऊपर means up, above, on top, or sometimes upstairs, depending on context.

In this sentence, with no reference object named, it most naturally means something like:

• upstairs
• up there
• above

If Hindi wants to say above something specific, that thing is usually mentioned:

• मेज़ के ऊपर = above the table / on the table

So:

• कपड़ों की टोकरी ऊपर है = The clothes basket is upstairs / up there

Because the main noun is टोकरी, and टोकरी is singular.

Even though कपड़ों is plural, it is only part of the of clothes phrase. The thing being talked about as the subject is the basket, not the clothes.

So:

• टोकरी ... है = the basket is ...
• if it were plural baskets, you would use हैं

The normal order here is:

[noun phrase] + [location] + [है]

So:

• कपड़ों की टोकरी ऊपर है।

This is the most neutral way to say it.

Hindi word order is somewhat flexible, though. For emphasis, you might also hear:

• ऊपर कपड़ों की टोकरी है।

That can sound more like Upstairs, there is the clothes basket or put more focus on the location.

But for a simple statement, कपड़ों की टोकरी ऊपर है is the standard pattern.

Roughly: kap-rõ

A few useful points:

• ड़ is a retroflex flap sound, somewhat like a quick flipped r/d sound
• ों makes the vowel nasalized

So the end is not a full on like English stone. It is more like a nasalized o sound.

If you want a learner-friendly approximation:

• कपड़ों ≈ kup-rohn with nasalization, though that is only approximate

Yes, it could, depending on context.

Because ऊपर is broad in meaning, the sentence might be understood as:

• The clothes basket is upstairs
• The clothes basket is up there
• The clothes basket is above
• The clothes basket is on top

Context tells you which one is meant. If the situation is inside a house, upstairs is very likely. If people are looking at stacked objects, on top may be more natural.
