As far as I know, a romantic meeting can be called a "date". They both like each other. But when you meet a person who provide you with a service such as a dentist, doctor, psychologist, lawyer..., it is called an "appointment". And when you meet someone for business, it's called a "meeting". However, if I just meet my friends or a new girlfriend, I can say: "I'm meeting/seeing friends/a new girlfriend. That's OK. "Learning English with Papa Teach Me" on Youtube said that. Both of them are full sentences, but I want a specific noun like "the first date" or "the first gathering" or "the first meeting". Which ones I can use? And if possible, could you explain your advice? Thanks in advance for any helping or advice.
