Hi joyce. I am good. Nice to meet you.

~^^ Thank you for teaching me . I am very busy nowadays. Because , I go to graduate school. I am studying to be a producer. I want to be an awesome producer and  I have to speak english very well. But English language is more difficult than Korean language. That's okay.

And I have a question. My N.Y friend said,  "Don't say 'Yes'. Yes is too- nerd expression in The states!!!Nobody say yes. So You say 'yeah'. Yeah is a formal expression , Don't worry

~ Yes  is used only in the law court!"

It's really? T.T???? Thanks~

Good day!

With the word " Yes ", it may be too-nerd to hear but that is actually the formal respond/word when you agree to someone especially when you are attending a meeting, conference, seminar, lecture and other formal gathering. We, as professional we have to use the appropriate words in a professional environment.  Even in our textbook, in some dialogues we could see the word "Yes" because that is sounds more formal. "Yeah" is the non-standard spelling of  "yes" as representing informal pronunciation.

However, it isn't wrong to use the word "yeah"  in conversation among friends.

For example:

"Did you find your wallet?"

"Yeah, I left it in the other room."

Thank you. Have a great day!
