भाई आज बाहर है।

भाई literally means brother. In context, it can also sound a bit like bro in casual speech, depending on who is speaking and to whom.

In a simple sentence like भाई आज बाहर है, the most neutral interpretation is Brother is out today or My brother is outside/out today, depending on context.

Hindi often leaves out words like my, your, or the when they are understood from context.

So:

• भाई आज बाहर है = Brother is out today
• मेरा भाई आज बाहर है = My brother is out today

Both are possible. The shorter version sounds natural if the listener already knows which brother is being talked about.

Also, Hindi does not have articles like a and the the way English does.

आज means today.

In this sentence:

• भाई = brother
• आज = today
• बाहर = outside / out
• है = is

So the sentence is literally something like:

Brother today outside is.

That is normal Hindi word order.

बाहर basically means outside. But in natural translation, it can also mean out, especially in sentences like this.

So भाई आज बाहर है could mean:

• Brother is outside today
• Brother is out today

Which English translation sounds best depends on context:

• If he is physically not inside the house, outside
• If he is away / not home / out somewhere, out

Because Hindi usually puts the verb at the end of the sentence.

English often uses:

• Subject + verb + complement
  Brother is outside

Hindi often uses:

• Subject + complement + verb
  भाई बाहर है

So है comes last because it is the verb is.

है means is in this sentence.

It is the present-tense form of the verb to be for:

• he/she/it is
• this is
• sometimes polite you are

Here it matches भाई, which is singular, so है is the correct form.

In Hindi, बाहर is not a verb. It is more like an adverb or location word meaning outside.
Then है supplies the idea of is.

So:

• बाहर = outside
• है = is

Together, बाहर है = is outside / is out

This is very common in Hindi.

Yes, you could also say आज भाई बाहर है.

Hindi word order is somewhat flexible, especially with time words like आज. The meaning stays very similar, but the emphasis can change slightly.

For example:

• भाई आज बाहर है = neutral, starting with brother
• आज भाई बाहर है = slightly more emphasis on today

Both are natural.

Hindi simply does not have articles that work like English a/an/the.

So भाई can mean:

• a brother
• the brother
• my brother
• just brother

The exact meaning depends on context.

That is why translation into English needs a small interpretation, even when the Hindi sentence is straightforward.

A simple pronunciation guide is:

• भाई = bhaai
• आज = aaj
• बाहर = baahar
• है = hai

Put together:

bhaai aaj baahar hai

A few notes:

• भ is an aspirated b sound, like b with a strong puff of air
• आ is a long aa sound
• है sounds roughly like hai, not like English hay exactly, but somewhat close

Yes, but the tone changes.

• भाई = brother / bro
• भैया = a more affectionate or familiar way to say older brother

So:

• भाई आज बाहर है = neutral
• भैया आज बाहर हैं or भैया आज बाहर है may be heard depending on region and style, but often भैया takes more respectful agreement in many contexts

A learner should start with भाई as the simplest, safest form unless the relationship or style specifically calls for भैया.
