Hi everyone, is yeah equal to yes? Are they interchangeable? For instance,
Person A: It is not a good idea.
Person B: Yes.
Here I know B does think it is a good idea, put another way, B disagrees with B on this issue.
Person B: well, yeah.
Here it is possible that B says yeah to imply he/she agrees with A on this matter. Am I right? That is to say, this is not a good idea.
The only difference between "yes" and "yeah" is the degree of formality.
There is no difference in intention.
If you simply answer "yes" to a negative statement, you will send a mixed message.
If you think it's not a good idea as well:
No, it really isn't.
If you think it *IS* a good idea:
Yes, it is.
I think it is.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
