बस शहर की ओर जा रही है।

Hindi usually forms the present progressive with:

main verb stem + रहा / रही / रहे + है / हैं

So:

• जा = go
• रही = progressive part, agreeing with a feminine singular subject
• है = is

So जा रही है means is going.

You cannot normally say जा है for is going.

Because बस is a feminine singular noun in Hindi.

In the present progressive, the रहा / रही / रहे part agrees with the subject:

• masculine singular: रहा
• feminine singular: रही
• plural: रहे

So:

• लड़का जा रहा है = the boy is going
• लड़की जा रही है = the girl is going
• बस जा रही है = the bus is going

That is why रही is used here.

की ओर means toward or in the direction of.

So:

• शहर की ओर = toward the city

This is a very common directional expression in Hindi.

You can think of it as a fixed phrase meaning toward X.

In X की ओर, the का / की / के part agrees with ओर, not with the noun before it.

Since ओर is treated as feminine, the form is की.

So the pattern is:

• घर की ओर = toward the house
• गाँव की ओर = toward the village
• शहर की ओर = toward the city

Even if the first noun is masculine, you still use की here because of ओर.

Many Hindi nouns do change in the oblique form before postpositions, but शहर is one of the nouns whose direct and oblique singular forms look the same.

So:

• direct: शहर
• oblique singular: शहर

That is why you still see शहर.

A noun like लड़का would show a clearer change:

• लड़का
• लड़के की ओर = toward the boy

But with शहर, the form stays the same.

Hindi normally places the verb at the end, so a very natural order is:

subject + direction/place + verb

Here that gives:

• बस = the bus
• शहर की ओर = toward the city
• जा रही है = is going

So the whole sentence follows a standard Hindi word order pattern.

Yes. That is very natural.

• की ओर = toward
• की तरफ = toward / in the direction of

So:

• बस शहर की ओर जा रही है
• बस शहर की तरफ जा रही है

Both are correct.
की तरफ often sounds a bit more conversational in everyday speech, while की ओर can sound slightly more formal or literary.

They express different meanings:

• जा रही है = is going right now / in progress
• जाती है = goes / habitually goes / generally goes

So:

• बस शहर की ओर जा रही है = the bus is going toward the city
• बस शहर जाती है = the bus goes to the city / the bus travels to the city

This is an important difference between progressive and habitual meaning in Hindi.

Hindi does not have articles like English a and the.

So बस can mean:

• a bus
• the bus

Which one is meant depends on context.

The same is true for शहर:

• a city
• the city

In this sentence, context tells you the intended meaning.

It is better to think of it as a verb phrase, not two separate full verbs in the English sense.

It contains:

• the main action: जा = go
• the progressive element: रही
• the auxiliary: है

Together they make one tense-aspect expression: is going.

So while it has multiple parts, it functions as one verbal unit.

Yes, that is also possible, but it is slightly different in nuance.

• बस शहर जा रही है = the bus is going to the city
• बस शहर की ओर जा रही है = the bus is going toward the city / in the direction of the city

शहर की ओर emphasizes direction.
It does not always guarantee arrival, only movement toward that place.

Yes, बस is normally treated as a feminine noun in standard Hindi.

That is why you say:

• बस आ रही है = the bus is coming
• बस जा रही है = the bus is going

If it were masculine, the sentence would use रहा instead of रही.

Then the agreement in the progressive part and auxiliary would change.

For example:

• बसें शहर की ओर जा रही हैं। = the buses are going toward the city

Changes:

• बस → बसें for plural
• है → हैं for plural

The progressive part often remains रही for feminine plural in modern standard Hindi when used with हैं in this structure, though learners will mainly want to notice the plural auxiliary हैं and the plural noun बसें.

ओर is pronounced roughly like or in English, but with a clearer, pure long o sound.

So:

• की ओर sounds approximately like kee or

Try to keep the Hindi vowels steady and not too diphthong-like.
