हम पार्क में मिलेंगे।

हम means we. It is the subject of the sentence.

In everyday Hindi, हम normally means more than one person, just like English we. In some dialects or special styles it can sometimes refer to I, but not in this standard sentence.

Because Hindi uses postpositions rather than prepositions.

• English: in the park
• Hindi: पार्क में = park in

So में means in / inside / at, and it comes after the noun.

It can mean either, depending on context.

With places like पार्क, Hindi often uses में where English might say either:

• in the park
• at the park

So हम पार्क में मिलेंगे। can naturally be understood as We’ll meet in the park or We’ll meet at the park.

मिलेंगे is the future form of मिलना, which means to meet.

So:

• मिलना = to meet
• मिलेंगे = will meet

In this sentence, it means will meet or will get together.

There is no separate word for will here.

Hindi usually shows the future tense by changing the verb itself. So मिलेंगे already includes the idea of will meet.

That means:

• हम = we
• पार्क में = in/at the park
• मिलेंगे = will meet

The ending -ेंगे shows a future form that matches हम in this sentence.

Very roughly:

• मैं मिलूँगा / मिलूँगी = I will meet
• हम मिलेंगे / मिलेंगी = we will meet

In the sentence हम पार्क में मिलेंगे।, मिलेंगे is the standard form for we will meet when the group is masculine or mixed, or when masculine is being used as the default.

Yes, it can.

A fully feminine plural version is:

हम पार्क में मिलेंगी।

So:

• मिलेंगे = masculine plural / mixed group / common default
• मिलेंगी = feminine plural

In real usage, मिलेंगे is often used as the general/default plural form, but grammatically मिलेंगी is the specifically feminine form.

Yes. Hindi often drops the subject when it is already clear from context.

So both of these can work:

• हम पार्क में मिलेंगे।
• पार्क में मिलेंगे।

The second one still means We’ll meet in the park if the context already makes we clear.

It is a very common loanword from English park, written in Devanagari as पार्क.

Modern Hindi uses many such borrowed words, especially for places and modern objects. So this sounds natural and normal.

Usually पार्क में is the natural choice here.

• में = in / at
• पर = on / at / upon

For a place like a park as an area or location, में is normally preferred. पार्क पर would sound less natural in this sentence unless a speaker had some special context in mind.

So the best version here is:

हम पार्क में मिलेंगे।

The most neutral word order is:

हम पार्क में मिलेंगे।

Hindi usually puts the verb near the end, so this is the standard pattern:

subject + place + verb

Other orders are possible for emphasis, such as:

• पार्क में हम मिलेंगे।
• हम मिलेंगे पार्क में।

But the original sentence is the most natural basic way to say it.
