What is the exact difference between to speak and to talk, cause the later wasn't accepted! ( here/in this case)
In Hindi, to talk is more precisely baat karnaa, though of course bolnaa is also used sometimes... The way I would attempt to differentiate is: "talk" has more to do with communicating a message and "speak" has more to do with producing a sound (vocally).
You can’t say ‘talk’ means x in Hindi and ‘speak’ means y. It’s what does the Hindi word mean in English. And in English talk and speak are interchangeable in this context.
Well even in English talking involves two actions - speaking and listening Where speaking is just one action of production legitimate sounds from your mouth
Just like in Hindi
Well Clint Eastwood would disagree. “I talk to the trees, but they don’t listen to me.” My wife talks to her plants - I’ve never heard them talk back! ;)
