Both “yup” and “yep” mean yes; “yep” sounds friendlier, while “yup” can sound casual or neutral.
Many people pause when choosing between yup and yep. Both words are informal ways to say “yes,” both appear in chats and social media, and both are widely understood. So why do people search for yup or yep?
