चेंजिंग रूम का लॉकर बंद है।

Because modern Hindi very often borrows everyday nouns from English, especially for places, objects, and modern settings. These borrowed words are simply written in Devanagari.

So:

• चेंजिंग रूम = changing room
• लॉकर = locker

This is completely normal in spoken and written Hindi, especially in urban contexts.

का is a possessive/genitive marker. It often works like of or ’s in English.

So चेंजिंग रूम का लॉकर means something like:

• the locker of the changing room
• the changing-room locker

It links the two nouns together.

Because का / की / के change to match the noun that comes after them — the thing being described or possessed.

Here, the following noun is लॉकर, which is treated as masculine singular, so Hindi uses का.

Basic pattern:

• masculine singular: का
• feminine: की
• plural: के

Examples:

• चेंजिंग रूम की चाबी = the changing room’s key
• चेंजिंग रूम के लॉकर = the changing room’s lockers

Hindi usually puts the possessor or related noun first, then का/की/के, then the main noun.

Pattern:

[related noun] + [का/की/के] + [main noun]

So:

• चेंजिंग रूम का लॉकर

This is the normal Hindi way to say the locker of the changing room or the changing-room locker.

Correct. Hindi does not normally use articles like a and the the way English does.

That means a sentence like this can be understood from context. Depending on the situation, it could mean:

• the changing room locker is closed
• a changing room locker is closed

Usually the context makes it clear which one is meant.

बंद means closed, shut, or sometimes not open.

With something like a locker, बंद है can often be understood as closed or locked, depending on context. In everyday speech, people use it very naturally for doors, shops, lockers, windows, etc.

Examples:

• दरवाज़ा बंद है = the door is closed
• दुकान बंद है = the shop is closed

If you want to be very specific that it is locked with a lock, Hindi might also use expressions like ताला लगा है.

No, in this sentence बंद is functioning like an adjective or state word: closed.

The actual is part is है.

So the structure is basically:

• लॉकर = locker
• बंद = closed
• है = is

Together: The locker is closed.

Because Hindi usually puts the verb or copula near the end.

A very common Hindi sentence order is:

subject + description/state + verb

So here:

• चेंजिंग रूम का लॉकर = subject
• बंद = state
• है = is

That is why है comes last.

Yes. In Hindi, का/की/के does not only show literal ownership. It can also show a general relationship or association.

So चेंजिंग रूम का लॉकर can naturally mean:

• the locker belonging to the changing room
• the locker used in the changing room
• the locker associated with that changing room

It does not have to mean that the room literally owns the locker.

Yes, but it may sound more formal or less natural in some everyday contexts.

A more Hindi-style version could be something like:

• कपड़े बदलने के कमरे का लॉकर बंद है।

But in real life, many speakers would still prefer चेंजिंग रूम and लॉकर, because those forms are very common and natural in modern Hindi.
