"Raj's uncle is eating."

Translation: राज के चाचा खा रहे हैं।

[Angela358686]

Both go together to convey respect for the चाचा

[anjit6]

Why is it rahe rather than rahi?

[LinguisticBoi]

respect

[k-popfanboy_arya]

चाचा is masculine so 'rahi hai' won't be used... And moreover, 'Rahe hai' is used because here we are talking about an elder person that is uncle. Yuh that's it

[HMz3gd]

Because chacha is masculine. So chacha/mama/fufa/papa kha rahe hain. Chachi/mami/bua/mummy kha rahi hain as they are feminine.

[Solinje]

It only says "paternal" for the uncle here, whereas चाची was specified to be the father's brother's wife (rather than father's sister) – does that mean it doesn't differentiate there?
