in English language when to use the words....tell / say....?

Answer 1

"Tell me a story..."
"So tell me, where are you from?"
"C'mon you can tell me..."

"You don't say...?"
"Say, this food is actually good..."
"Well, you know what they say..."


And there are sooo many more examples.... look it up in a Grammer book or the encyclopedia....

Answer 2

You use tell when you are asking someone to "tell a story" so instead of one quick specific response you're looking for an elaboration.

You use say for the specific act of "saying something".

Of course, it's not that simple. When you ask someone to speak to you about something, you wouldn't use "say", you would use "tell". So actually, even if it is something specific, you would say "please tell me the answer to this question". You would not say "say me the answer".

Hmm.. I don't know if that's helpful, it's the best I could do as a layperson not an expert in grammar.

Answer 3
