प्रारंभिक स्टेशन और गंतव्य सही हैं।

Because the subject is compound: प्रारंभिक स्टेशन और गंतव्य = the starting station and the destination.

In Hindi, when two nouns are joined by और (and), they usually count as plural, so the verb is plural too:

• है = is
• हैं = are

So:

• स्टेशन सही है। = The station is correct.
• गंतव्य सही है। = The destination is correct.
• स्टेशन और गंतव्य सही हैं। = The station and destination are correct.

Because सही is an adjective that normally stays unchanged.

Some Hindi adjectives change depending on gender and number, such as:

• अच्छा (masculine singular)
• अच्छी (feminine singular)
• अच्छे (masculine plural / mixed plural)

But सही is an indeclinable adjective, so it does not change:

• सही आदमी = correct/right man
• सही बात = correct/right thing
• सही हैं = are correct

So even though the subject is plural, सही still remains सही.

प्रारंभिक is an adjective describing स्टेशन.

It means something like:

• initial
• starting
• origin
• departure (depending on context)

So प्रारंभिक स्टेशन means starting station or origin station.

This is a more formal word than very everyday alternatives. In transportation or interface language, it can sound quite natural.

गंतव्य is a noun meaning destination.

It is somewhat formal and is often seen in:

• travel contexts
• maps
• booking systems
• announcements
• official or written Hindi

In casual conversation, people might sometimes use other expressions depending on context, but गंतव्य is absolutely a standard and correct word.

In this sentence, it is simply the second noun in the subject:

• प्रारंभिक स्टेशन = starting station
• गंतव्य = destination

Together: the starting station and destination

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

So Hindi often says just the noun, and context tells you whether English would use:

• a
• the
• no article at all

For example:

• स्टेशन can mean station, a station, or the station
• गंतव्य can mean destination, a destination, or the destination

So प्रारंभिक स्टेशन और गंतव्य सही हैं naturally has no separate word for the.

Hindi often puts the predicate adjective before the verb to be, so the structure here is:

• [subject] + [adjective] + [verb]

In this sentence:

• प्रारंभिक स्टेशन और गंतव्य = subject
• सही = adjective/predicate
• हैं = are

So literally it is:

• Starting station and destination correct are.

That is normal Hindi word order.

English requires:

• The starting station and destination are correct.

और means and.

It joins the two nouns:

• प्रारंभिक स्टेशन
• गंतव्य

So:

• प्रारंभिक स्टेशन और गंतव्य = the starting station and the destination

Because और joins two items, the subject becomes plural, which is why the sentence uses हैं.

Because the nouns here are simply the subject of the sentence.

Hindi uses postpositions like:

• को for certain objects/recipients
• का / की / के for possession
• में for in
• से for from/with

But in this sentence, the speaker is just identifying what is correct:

• प्रारंभिक स्टेशन और गंतव्य = subject
• सही हैं = are correct

So no extra postposition is needed.

स्टेशन is a borrowing from English station.

Hindi uses many English loanwords, especially for:

• transport
• technology
• administration
• modern daily life

Even though it comes from English, it behaves like a normal Hindi noun in sentences.

So in प्रारंभिक स्टेशन, you have:

• प्रारंभिक = a Sanskrit-based/formal Hindi adjective
• स्टेशन = an English loanword

That kind of mixing is very common in modern Hindi.

Yes. प्रारंभिक can be translated in a few ways depending on context.

Possible English renderings include:

• initial station
• starting station
• origin station
• departure station

In a travel or booking interface, starting station or origin station is usually the most natural interpretation.

So the exact English wording may vary, but the Hindi grammar stays the same.

Gender exists in Hindi, but in this sentence it does not affect much on the surface.

Why?

1. सही does not change for gender.
2. The subject is compound/plural, so the verb is हैं anyway.
3. प्रारंभिक also does not visibly change here.

So even if a learner is unsure about the gender of स्टेशन or गंतव्य, the sentence still looks the same:

• प्रारंभिक स्टेशन और गंतव्य सही हैं।

That is one reason this sentence is fairly straightforward grammatically.
