किराए पर बहस हुई।

Because किराया changes to its oblique form before a postposition like पर.

• Direct form: किराया
• Oblique form: किराए
• With postposition: किराए पर

This is very common with masculine singular nouns ending in -आ.

For example:

• कमरा → कमरे में
• लड़का → लड़के से
• किराया → किराए पर

So किराए पर is grammatically the expected form.

Here, किराए पर means something like about the rent or over the rent.

Even though पर often literally means on, Hindi often uses it with nouns like बहस, चर्चा, and विवाद to mean on/about/regarding a topic.

So in this sentence, किराए पर does not mean a physical location. It marks the topic of the argument.

Literally, बहस हुई means an argument/discussion happened or a debate took place.

• बहस = argument, debate, discussion
• हुई = happened / took place

Hindi often uses होना this way for events:

• मीटिंग हुई = a meeting happened
• लड़ाई हुई = a fight happened
• बहस हुई = an argument happened

So this structure is very natural in Hindi.

Because बहस is a feminine singular noun, and the verb agrees with it.

• बहस = feminine singular
• therefore: हुई

Compare:

• झगड़ा हुआ — झगड़ा is masculine
• बहस हुई — बहस is feminine
• मीटिंग हुई — मीटिंग is feminine

So the verb form matches the gender and number of the noun that is doing the happening.

Because Hindi often expresses events impersonally.

In English, you might say:

• They argued about the rent
• There was an argument about the rent

Hindi very naturally says:

• किराए पर बहस हुई

The focus is on the event itself, not on who argued. The people involved are left unstated because they are either unknown, obvious from context, or simply not important.

Because this sentence is not built around a transitive perfective verb with an agent.

ने is commonly used when:

• there is a doer/agent
• the verb is perfective
• the verb is transitive

But here, the structure is basically:

• बहस हुई = an argument happened

This is an intransitive event happened type of sentence, so ने is not used.

If you changed the structure to something like उन्होंने किराए पर बहस की, then ने would appear:

• उन्होंने किराए पर बहस की = they argued about the rent

Yes, it is natural. Hindi word order is flexible, but this version is very normal.

This order puts the topic first:

• किराए पर = about the rent
• बहस हुई = an argument happened

You could also hear:

• बहस किराए पर हुई

That version is also possible, but it may sound more contrastive or context-dependent, as if you are emphasizing what the argument was about.

So the given sentence is a straightforward, natural way to say it.

Yes, but the tone changes a little.

You could say:

• किराए के बारे में बहस हुई

This also means that the argument was about the rent. However, with nouns like बहस, चर्चा, and विवाद, पर is often shorter and more idiomatic.

Compare:

• किराए पर बहस हुई — compact, very natural
• किराए के बारे में बहस हुई — also correct, slightly more explicit

So both are possible, but पर is especially common in this kind of sentence.

Yes. बहस can cover a range of meanings depending on context:

• argument
• dispute
• debate
• verbal discussion

So the exact English choice depends on the situation:

• angry disagreement → argument
• formal exchange of views → debate
• general verbal back-and-forth → discussion

In this sentence, without more context, argument or debate/dispute could all fit.

A common transliteration is:

kirāe par bahas huī

A few pronunciation notes:

• कि = ki
• रा = long rā
• ए in किराए is pronounced like a separate vowel sequence: kirā-e
• बहस = bahas
• हुई = huī or sometimes written hui

So it is roughly pronounced: ki-raa-e par ba-has हू-ई

Normally, no. In this sentence, native speakers will naturally understand किराए पर as the topic of the argument: over the rent.

That is because:

• बहस ... पर is a very common pattern meaning argument/debate about ...
• the combination strongly points to topic, not location

If you wanted to talk about an argument happening in a rented house or rented room, you would usually say that much more clearly, for example:

• किराए के घर में बहस हुई
• किराए के कमरे में बहस हुई

So in the given sentence, the intended reading is the standard one: the argument was about rent.
