वह लड़की बस में है; वह आदमी स्टेशन पर बैठा है।

वह can mean he, she, or that. Hindi does not normally distinguish he and she with different everyday pronouns the way English does.

So in context:

• वह लड़की can mean that girl or the girl/she
• वह आदमी can mean that man or the man/he

The exact English choice depends on context and the translation you have been given.

Hindi has no articles that work like English a/an and the.

So:

• लड़की can mean girl, a girl, or the girl
• आदमी can mean man, a man, or the man

Context tells you which English article sounds natural.

They are postpositions. That means they work like English prepositions, but they come after the noun instead of before it.

Examples from the sentence:

• बस में = in/on the bus
• स्टेशन पर = at the station

So Hindi says something more like:

• bus in
• station at

This is completely normal in Hindi.

Hindi usually uses में with enclosed vehicles such as:

• बस में = on/in the bus
• ट्रेन में = on/in the train
• कार में = in the car

English often says on the bus and on the train, but Hindi typically uses में, literally in. So this is a translation difference between the two languages, not a mistake.

स्टेशन पर usually means at the station as a location.

Hindi often uses पर when someone is at a place in a general sense:

• स्कूल पर
• स्टेशन पर
• दरवाज़े पर

If you specifically want to emphasize being inside the station building, स्टेशन में can be possible in some contexts. But for ordinary at the station, स्टेशन पर is the natural choice here.

बैठा है means is sitting or is seated.

In this sentence:

• वह आदमी स्टेशन पर बैठा है = The man is sitting at the station

Literally, बैठा is a form related to sat/seated, and है means is. Together, they describe the man’s state or posture.

So this is different from just saying where he is. It tells you what position he is in.

Because बैठा agrees with आदमी, which is masculine singular.

In Hindi, words like बैठा / बैठी / बैठे often change to match gender and number.

Here:

• आदमी is masculine singular
• so you use बैठा है

If it were a woman or girl, you would say:

• वह लड़की स्टेशन पर बैठी है = The girl is sitting at the station

Yes, that can confuse learners.

Even though आदमी ends in -ी, it is still a masculine noun. In Hindi, noun gender is not always predictable from the ending alone.

So you have to learn the gender of some nouns individually. That is why:

• आदमी बैठा है is correct
• आदमी बैठी है is incorrect

Hindi usually puts the verb at or near the end.

So:

• वह लड़की बस में है
  literally: that girl bus in is

• वह आदमी स्टेशन पर बैठा है
  literally: that man station at sitting/seated is

A good simple pattern is:

• subject + place/other information + verb

This is one of the most important differences from English.

Yes, Hindi can often drop pronouns when the meaning is clear from context. But repeating वह here makes the sentence clearer and neatly balances the two clauses:

• वह लड़की बस में है; वह आदमी स्टेशन पर बैठा है।

This gives a nice contrast:

• the girl is in the bus
• the man is sitting at the station

If you removed the second वह, the sentence could still be understandable in some contexts, but the repeated form is very natural and clear.

A helpful transliteration is:

vah laṛkī bas mẽ hai; vah ādmī sṭeśan par baiṭhā hai

A few quick notes:

• वह is often pronounced closer to voh in everyday speech
• ड़ in लड़की is a flap sound not found exactly in English
• में has nasalization on the vowel
• ठ in बैठा is an aspirated retroflex sound

You do not need perfect pronunciation immediately, but recognizing the rhythm helps a lot.
