"उन्हें खाना चाहिए।"

Translation: They want food.

[Olivier216505]

Also translates to "They should eat", although I don't think this construction has been seen yet

[emrys29]

Yes.
The should eat, should be accepted.

[KaivalyaKu6]

What about "they need food"

[bannigeri]

Anything that makes this specifically "they want food", vs. "he wants food" or "she wants food"?

[Olivier216505]

Yes, and no. It's उन्हें, so it's grammatically plural, but it would work if this is said talking about an elderly to whom you give respect. I might be wrong for the use of उन्हें for respect though.

[emrys29]

You're right.
उन्हें बुलाओ can mean "call him" or "call them" depending on context.

[acegirl_6]

What's the difference between उन्हें and उसे?

[Gita-ji]

उन्हें is the plural form for the oblique pronoun (to them) while उसे is the singular form (to him/her/it).

[Shankhari]

What's the difference between उन्हें and उनको?

[Kowaz]

उन्हें = वे + को = to them

(edited after Jetley's remarque)

[Jelley]

No difference. Either can be used for उन [ oblique case form of वे ] + को

Plural masculine possessive pronoun would be: उनके

[Kowaz]

Thank you Jetley. I corrected my previous message.

[aliceriot]

उन्हें is the 'short form' of उनको. there are other for other pronouns, like मुझको becomes मुझे and others.

technically the 'short form' is the dative form of the pronouns, check out wikipedia for more info: https://en.wikipedia.org/wiki/Hindustani_grammar#Pronouns

Why is there no हैं in the end? How would this sentence be translated directly?

[ExcelsiorProHrig]

In other way, it means "we should eat them".

[Prishasaib]

Mujhe samajh Nahin a Raha

[Prishasaib]

Mujhe yah Samajh Mein Nahin a Raha
