यह बैग उस बैग से महँगा है, लेकिन इसकी कीमत बहुत ज़्यादा नहीं है।

A very literal breakdown is:

• यह = this
• बैग = bag
• उस बैग से = than that bag / from that bag
• महँगा = expensive
• है = is

So the structure is basically:

This bag is expensive from that bag
which in natural English means: This bag is more expensive than that bag.

Hindi often uses X से to express comparison.

In Hindi, से is commonly used to mean than in comparisons.

So:

• उस बैग से महँगा = more expensive than that bag
• राम मोहन से लंबा है = Ram is taller than Mohan
• यह किताब उस किताब से अच्छी है = This book is better than that book

Although से often also means from, in comparison sentences it usually means than.

Because वह changes to उस before a postposition like से.

This is called the oblique form.

• direct form: वह बैग = that bag
• oblique form: उस बैग से = than/from that bag

The same thing happens with यह:

• direct form: यह बैग = this bag
• oblique form: इस बैग का / इस बैग से / इस बैग में

So once a noun or pronoun is followed by a postposition, Hindi usually uses the oblique form.

For the same reason: the form changes depending on grammar.

At the start:

• यह बैग = this bag
  No postposition follows यह, so the direct form is used.

Later:

• इसकी कीमत = its price / this one’s price
  Here the pronoun is part of a possessive construction, so the oblique base इस- is used.

This pattern is very common:

• यह → direct
• इस → oblique base
• इसका / इसकी / इसके → possessive forms

इसकी means its or of this.

In this sentence, it refers to this bag:

• इसकी कीमत = this bag’s price / its price

So the second clause:

लेकिन इसकी कीमत बहुत ज़्यादा नहीं है
means
but its price is not very high

or more naturally,
but it is not very expensive / but the price is not very high

Good question. The form का / की / के agrees with the thing being possessed, not with the owner.

Here:

• owner = this bag
• possessed thing = कीमत (price), which is feminine

So Hindi says:

• इसकी कीमत = its price

because कीमत is feminine singular, so की is required.

Compare:

• इसका रंग = its color (रंग is masculine)
• इसकी कीमत = its price (कीमत is feminine)
• इसके पैसे = its money / its costs (पैसे plural)

Yes. महँगा is an adjective and it agrees with the noun बैग.

Since बैग is generally treated as masculine singular in Hindi, the adjective appears as:

• महँगा = masculine singular

If the noun were feminine singular, you would get:

• महँगी

For example:

• यह घड़ी महँगी है = This watch is expensive

And plural masculine often becomes:

• महँगे

So yes, महँगा matches बैग.

The sentence is making two related but slightly different statements:

1. यह बैग उस बैग से महँगा है
   = This bag is more expensive than that bag.

2. लेकिन इसकी कीमत बहुत ज़्यादा नहीं है
   = But its price is not very high.

The first part is a comparison.
The second part softens that comparison: even though this bag costs more than that one, the price is still not extremely high.

So कीमत is used to talk specifically about the price.

They are related, but together they naturally mean too much / very much / very high depending on context.

Here:

• बहुत ज़्यादा नहीं है = is not very much / is not too high / is not excessively high

In this sentence, a natural English rendering is:

• is not very high
• is not too expensive
• is not that expensive

So बहुत ज़्यादा adds emphasis. It makes the phrase stronger than just ज़्यादा नहीं है.

Yes.

• इसकी कीमत ज़्यादा नहीं है = Its price is not high / not much
• इसकी कीमत बहुत ज़्यादा नहीं है = Its price is not very high / not too high

The version with बहुत sounds a bit more emphatic or natural in many situations.

In simple Hindi clauses, नहीं usually comes before the verb or verb phrase.

So:

• कीमत ... नहीं है = the price is not ...
• वह नहीं आता = he does not come
• मैं नहीं जानता = I do not know

That is the normal position for negation in sentences like this.

लेकिन means but.

It connects two contrasting ideas:

• This bag is more expensive than that bag
• but its price is not very high

So the contrast is:

more expensive than that one
vs.
still not very expensive overall

बैग is a borrowed word from English bag, but it is commonly used in Hindi.

Like many borrowed nouns, it still gets assigned a grammatical gender in Hindi usage. In most everyday Hindi, बैग is usually treated as masculine, which is why the sentence has:

• महँगा rather than महँगी

Learners should remember that borrowed words in Hindi still behave like Hindi nouns grammatically.

Yes, absolutely.

• इसकी कीमत बहुत ज़्यादा नहीं है
• इस bag की कीमत बहुत ज़्यादा नहीं है

Both are correct.

The version with इसकी is shorter and smoother because Hindi often uses pronouns instead of repeating the noun.

So:

• इसकी कीमत = its price
• इस बैग की कीमत = this bag’s price

In English we say:

• more expensive than

Hindi often does this differently:

• X, Y से महँगा है

So the idea of more ... than is expressed through:

1. the adjective (महँगा)
2. the comparison marker से

Hindi usually does not need a separate word exactly matching English more in this kind of sentence.

The sentence follows a very typical Hindi pattern:

यह बैग | उस बैग से | महँगा है, | लेकिन | इसकी कीमत | बहुत ज़्यादा नहीं है।

You can think of it as:

• topic/subject: यह बैग
• comparison phrase: उस बैग से
• adjective + verb: महँगा है
• contrast: लेकिन
• possessive phrase: इसकी कीमत
• predicate: बहुत ज़्यादा नहीं है

Hindi usually places the verb near the end of the clause, unlike English.

In महँगा, the mark ँ shows nasalization.

So महँगा is pronounced roughly like mahngaa with a nasal sound on the vowel.

That nasalization is an important part of the word. Without it, the pronunciation would be different.

Also, ज़्यादा contains ज़, which is a dotted ज. In many speakers’ Hindi, ज़ and ज may sound similar, but the spelling ज़्यादा is standard.

Not exactly.

The Hindi sentence says:

• This bag is more expensive than that bag
• but its price is not very high

That means the overall price is not very high, not necessarily that the difference between the two bags is small.

If you wanted to say not by much, Hindi would need a different expression, such as something like:

• यह बैग उस बैग से थोड़ा ही महँगा है
  = This bag is only a little more expensive than that bag.

So the original sentence is about the absolute price, not the size of the difference.
