बस लगभग पहुँच गई है।

Because बस is a feminine noun in Hindi. In many perfective-style expressions, the verb agrees with the subject when there is no ने marker blocking agreement.

So:

• बस ... गई है = feminine singular
• ट्रेन ... गई है = feminine singular
• लड़का ... गया है = masculine singular
• लड़कियाँ ... गई हैं = feminine plural

Here, गई matches बस.

Not really. Although गई is historically the feminine form of जाना (to go), in sentences like this it often works as part of a compound verb.

So पहुँच गई है is best understood as a unit meaning something like:

• has arrived
• has gotten there
• has reached

The गई adds a sense of completion or successful arrival, rather than independently meaning went.

है is the present-tense auxiliary here. It helps form a present perfect/resultative meaning.

Compare:

• बस पहुँच गई। = The bus arrived.
• बस पहुँच गई है। = The bus has arrived / The bus is arrived now.

So गई gives the completed/resultative idea, and है places that result in the present.

लगभग usually means approximately, roughly, nearly, or almost.

In this sentence, it means almost/nearly, not approximately in a numerical sense.

So the idea is:

• बस लगभग पहुँच गई है = The bus has almost arrived / The bus is nearly here.

Hindi uses लगभग both with numbers and with states/actions:

• लगभग दस बजे = about ten o’clock
• लगभग तैयार = almost ready
• लगभग पहुँच गई है = has almost arrived

Because it modifies the whole verbal idea: has arrived / reached.

Hindi often places adverbs like लगभग before the main verb phrase:

• वह लगभग तैयार है।
• मैं लगभग भूल गया था।
• बस लगभग पहुँच गई है।

That is the most natural position here. You may hear slight variations in speech, but this order is standard and clear.

Because पहुँचना is an intransitive verb: the subject arrives, but there is no direct object being acted on.

In standard Hindi, ने is commonly used with many transitive perfective clauses, but not with verbs like पहुँचना.

So:

• बस पहुँच गई है = correct
• बस ने पहुँच गई है = incorrect

This is a very common pattern with intransitive verbs of movement or change of state.

Yes, in natural English that is often a good translation, even though the Hindi structure is literally closer to has almost arrived.

Depending on context, बस लगभग पहुँच गई है can suggest:

• the bus is nearly here
• the bus has almost reached
• the bus is about to arrive

If you want a more explicitly about to structure in Hindi, you could also say:

• बस पहुँचने वाली है।

That version focuses more directly on something being imminent.

They are close, but not identical.

बस लगभग पहुँच गई है

• literally: the bus has almost arrived
• suggests it is very close to arrival
• often sounds like the bus is already on the way and nearly here

बस पहुँचने वाली है

• literally: the bus is about to arrive
• focuses on imminence
• often used when something is expected very soon

In many situations, both are acceptable. The first can sound a bit more like the process is nearly complete; the second more like the event is just about to happen.

Yes, but the nuance is a little different.

• बस पहुँची है = the bus has arrived
• बस पहुँच गई है = the bus has arrived / managed to arrive / is now there

The version with गई is very common in everyday Hindi and often sounds more natural in conversation. It gives a stronger sense of completed arrival.

With लगभग, however, बस लगभग पहुँच गई है sounds especially natural for the bus is nearly here.

पहुँच is pronounced roughly like pahunch.

The mark ँ is a nasalization mark called chandrabindu. It nasalizes the vowel sound. So हुँ is not just hu; it is more like a nasalized hun sound.

A rough breakdown:

• प = pa
• हुँ = hũ
• च = ch

So: pa-hũch

Learners often find this word tricky at first, but it becomes familiar quickly because पहुँचना is a very common verb.

Good question. बस has multiple meanings in Hindi.

Common ones include:

• bus (the vehicle)
• enough / that’s enough
• sometimes just / only in certain contexts

In बस लगभग पहुँच गई है, it clearly means the vehicle, because the rest of the sentence describes something arriving, and the feminine agreement in गई also fits बस as a noun.

So meaning depends heavily on context.

Not in this sentence. लगभग पहुँच गई है is perfectly natural.

However, English and Hindi do not always line up exactly in how almost works. In Hindi, लगभग can comfortably modify a completed-result expression like पहुँच गई है to mean nearly there / almost arrived.

So even though the structure looks a bit like has arrived, the addition of लगभग makes the intended meaning clear: the arrival is very close, but not fully completed yet.

The dictionary form is पहुँचना, meaning to arrive / to reach.

In this sentence:

• पहुँच = the verb stem/root used in the compound
• गई = feminine form of जाना used in the compound
• है = present auxiliary

So the full verbal expression is built from पहुँचना, but it appears here in a natural spoken compound form: पहुँच गई है.
