Get in the habit of using the proper noun for the specific type of meeting, booking, or get-together you are having.
Appointment: We use appointment when we are meeting with a professional or a specialist (doctor, banker, lawyer, broker, etc...). We use the verb "make" or "schedule" in combination with the noun "appointment".
"I made a dentist appointment at three o'clock." "I have to schedule an appointment with my financial advisor for sometime later this week."
Do you have to make an appointment in Korea to see a doctor or do you just drop by?
Reservation: We use the noun reservation when we are arranging to have something held until a later time (hotel room, restaurant table, seat). Use the verb "make" in combination with the noun "reservation".
"Did you make a reservation at Bon a Petit restaurant for this Friday?" "Did you reserve enough seats for everyone at the fashion show?"
What was the last occasion where you had to make a reservation?
Book: While "book" is very similar to reservation there is a slight difference. "Book" is more commonly used when the individual has already paid in full for a service.
"I booked a magician for the party." "I booked the banquet hall for the 23rd of this month." "I booked our flight tickets, but I didn't reserve our seats yet."
What method do you use when you book a flight (travel agent, online)?
Get together: We usually use "get together" when we are meeting a group of friends for an informal social event. We can also use "get-together" as a noun.
"I'm going to get together with my old college friends this weekend. We will likely go bowling." "Let's have a get-together before the wedding on Friday at my place."
When was the last time you got together with your school friends? How often do you get together with co-workers?
Hang out: Young people often use "hang out" or "chill" when they want to spend time together. If you are in your late twenties or older, maybe you should pass on this one.
"If you're not busy this weekend, maybe we can hang-out on Saturday?" "I hung out with Dan last weekend, he said hello."
Where do young people hang out in your city? Where did you and your friends hang out when you were younger?
Visit: We often use "visit" with family or when we are going to someone's home.
"I'm going to visit my in-laws this weekend in Seoul."
How often do you visit your extended family? What types of gifts are common when visiting family or friends at their home?
Always be mindful of the tense (past, present, and future).
"I hung out with my friends yesterday." "Tomorrow I am going to hang out with my friends."
"I got together with my co-workers yesterday." "I will get together with my co-workers this weekend."
"I made an appointment for 4:30 tomorrow." "I will make an appointment for 4:30 tomorrow."
1.) "First come, first serve": This means that a restaurant or establishment does not take reservations. Those who arrive first are served or seated first.
"That restaurant always has a huge line." "Yeah, they don't take reservations, it's first come first serve."
2.) "Paid in full": Means you have already paid the complete cost of a service or product, sometimes before actually receiving the product or service.
"The live band requires 50% down payment, but the photographer needs to be paid in full before confirming a booking." "Nice car, are you leasing?" "No, It's paid in full."
