मुझे उस शहर का नाम याद है, लेकिन मुझे उस गाँव का नाम याद नहीं है।

Because Hindi expresses remembering differently from English here.

In English, you say I remember... and I is the subject.

In Hindi, this pattern is more like:

To me ... remembered is

So मुझे means to me, not plain I. This is a very common Hindi structure for feelings, experiences, and mental states.

So:

मुझे ... याद है
literally: To me ... is remembered
natural English: I remember ...

याद relates to memory or being remembered, and है means is.

So याद है literally means something like:

is remembered
or
is in memory

In natural English, depending on context, it can mean:

• I remember
• I know by memory
• I still remember

In this sentence:

मुझे उस शहर का नाम याद है
means I remember the name of that city.

Because उस is the oblique form of वह.

Hindi pronouns often change form when they come before a postposition such as का, को, में, से, etc.

Here, the phrase is:

उस शहर का नाम

The postposition का applies to the noun phrase उस शहर, so the pronoun must take its oblique form:

• वह = direct form
• उस = oblique form

Compare:

• वह शहर = that city
• उस शहर का नाम = the name of that city

Literally, it means:

that city’s name

Breakdown:

• उस = that
• शहर = city
• का = of / ’s
• नाम = name

So:

उस शहर का नाम = the name of that city

This is a very common Hindi structure:

X का नाम = the name of X

For example:

• उस आदमी का नाम = the name of that man
• उस किताब का नाम = the name of that book

Because का / की / के agrees with the noun that comes after it here, which is नाम.

नाम is masculine singular, so Hindi uses का:

• का = masculine singular
• की = feminine singular
• के = masculine plural or respectful/plural contexts

So:

• उस शहर का नाम
• उस गाँव का नाम

both use का, because नाम is masculine singular.

Because many Hindi nouns do not visibly change in the singular oblique form, especially nouns that do not end in -आ.

Both शहर and गाँव stay the same in direct and singular oblique use.

So you get:

• वह शहर
• उस शहर का नाम

and

• वह गाँव
• उस गाँव का नाम

The pronoun changes (वह → उस), but the nouns शहर and गाँव stay the same.

Yes, very often.

The full sentence repeats it for clarity and balance:

मुझे उस शहर का नाम याद है, लेकिन मुझे उस गाँव का नाम याद नहीं है।

A natural shorter version is:

मुझे उस शहर का नाम याद है, लेकिन उस गाँव का नाम याद नहीं है।

Both are correct. Repeating मुझे makes the contrast a little clearer and more rhythmic.

In Hindi, नहीं usually comes before the verb or verb phrase element it negates.

So:

• याद है = is remembered / I remember
• याद नहीं है = is not remembered / I do not remember

This placement is very normal in Hindi:

• वह यहाँ है = he is here
• वह यहाँ नहीं है = he is not here

So याद नहीं है is the standard order.

Hindi usually follows Subject/Object/Other information + Verb order, but this sentence uses an experiencer pattern.

A rough structure is:

मुझे = to me
उस शहर का नाम = the name of that city
याद है = is remembered

So the full sentence is basically:

To me the name of that city is remembered, but to me the name of that village is not remembered.

That sounds strange in English, but it is a normal Hindi way to express I remember... / I don’t remember...

Yes. लेकिन is a very common and natural word for but.

So:

..., लेकिन ... = ..., but ...

Other words such as पर can also mean but in many contexts, but लेकिन is completely standard and clear here.

गाँव is pronounced approximately like gaãv.

The mark ँ shows nasalization of the vowel. That means the vowel is pronounced with air going through the nose as well.

So गाँव is not just gaav. It is more like:

gaãv

Also, the final व here often sounds closer to an English v/w type sound depending on accent.

So a learner should especially notice the nasalized vowel in गाँव.

It is natural and correct Hindi.

It sounds a little full because the second clause repeats several words, but that is still perfectly normal. In everyday speech, people might shorten it slightly if the context is clear:

मुझे उस शहर का नाम याद है, लेकिन उस गाँव का नहीं।

That shorter version is also very natural. But the original full sentence is excellent for learning because it shows the structure clearly.
