Formal greetings show respect to whomever you’re speaking to.

Here are some examples of how to formally greet someone in Dutch:

1. Goedemorgen – Good morning.

2. Goedenmiddag – Good afternoon.

3. Goedenavond – Good evening.

4. Hoe gaat het met u? – How are you?

5. Tot ziens – Goodbye (It literally means “until I see you again”, but it is more like “good bye” in English.)

6. Dank u wel – Thank you.

7. Alstublieft – Please.

8. Aangenaam – Nice to meet you. ( https://dutchforbeginners.com/formal-greetings-in-dutch )
