Yes
expression
Want me to write a haiku (はい)? Yes, of course!
はい is a formal word for "yes". You can use it to let someone know they’re right, or simply that you’re listening, as well as to respond if someone says your name.
はい、そうです
yes that's right
はい、もちろん
yes of course
はい、いいですよ
yes that's fine
「チャンドラーさん」「はい！」
"Mr. Chandler." "Yes!"
はい、ありがとうございます。
Yes, thank you very much.
はい、分かりました。
Yes, understood.
