बेडरूम रोशन है।

A natural pronunciation is roughly:

beḍrūm roshan hai

More approximately for an English speaker:

• बेडरूम = bed-room
• रोशन = ro-shun or ro-shan
• है = hai, sounding a bit like heh or hai depending on accent

So the full sentence sounds like:

bed-room ro-shan hai

Because Hindi often uses loanwords from English, especially for everyday modern objects and rooms in a house.

So बेडरूम is just the English word bedroom, written in Devanagari script.

This is very common in Hindi. For example:

• कार = car
• बस = bus
• टीवी = TV
• बेडरूम = bedroom

Hindi does not normally use articles like English a/an/the.

So बेडरूम रोशन है can mean:

• The bedroom is bright
• A bedroom is bright
• The bedroom is lit

The exact meaning depends on context.

In Hindi, the verb usually comes at the end of the sentence.

So the structure here is:

• बेडरूम = bedroom
• रोशन = bright / lit
• है = is

Literally, Hindi is doing something like:

Bedroom bright is.

That is normal Hindi word order.

रोशन means something like:

• bright
• lit
• illuminated

In this sentence, it suggests that the bedroom has light in it or looks bright.

Depending on context, English translations could be:

• The bedroom is bright.
• The bedroom is lit up.
• The bedroom is illuminated.

Yes. In this sentence, रोशन describes बेडरूम, so it is functioning like an adjective or predicate adjective.

Compare in English:

• The bedroom is bright.

Here, bright describes the bedroom.
In the same way, रोशन describes बेडरूम.

Because रोशन is commonly used as an indeclinable adjective in Hindi. That means it often stays the same instead of changing for gender or number.

So you can see:

• कमरा रोशन है = The room is bright.
• रसोई रोशन है = The kitchen is bright.
• कमरे रोशन हैं = The rooms are bright.

Notice that रोशन stays रोशन.

What changes more clearly is usually the form of to be:

• है for singular
• हैं for plural

Loanwords from English can sometimes vary in usage, but बेडरूम is commonly treated as masculine, partly by association with कमरा (room), which is masculine.

In this sentence, though, you cannot really tell from रोशन, because रोशन does not change form here.

You would notice agreement more clearly in other kinds of sentences.

In normal standard Hindi, no—you usually keep है in a sentence like this.

So the standard sentence is:

बेडरूम रोशन है।

If you drop है, it may sound incomplete, poetic, headline-like, or very colloquial in certain situations, but it is not the normal full sentence for a learner to use.

Yes. A very common alternative is:

बेडरूम में रोशनी है।

This means:

• There is light in the bedroom.

The nuance is slightly different:

• बेडरूम रोशन है focuses on the bedroom being bright/lit
• बेडरूम में रोशनी है focuses on there being light in the bedroom

Both are natural, but they are not exactly identical.

The pattern is:

[noun] + [description] + है

So:

• बेडरूम = noun
• रोशन = description
• है = is

You can make similar sentences:

• कमरा साफ है। = The room is clean.
• घर बड़ा है। = The house is big.
• रसोई गर्म है। = The kitchen is warm.

This is a very useful basic Hindi sentence pattern.

It is a perfectly normal sentence, but रोशन is a slightly more literary or descriptive word than some very basic alternatives.

In everyday speech, people might also say things like:

• बेडरूम में लाइट है।
• बेडरूम में उजाला है।

Still, बेडरूम रोशन है is natural and correct, especially in descriptive speech or writing.
