Hi! First post in a while 😭. I want to make a post about Yeah vs Yes. Is it slang? Well… no. Not really. Yeah is actually much older than Yes as a word. Yes is more formal too! In general conversation with friends yeah is always normal. Yes can even be a bit, ‘official’ 😀. And if my girlfriend started saying ‘yes Matthew’ to everything I would think she was being passive aggressive 🙂.
