First off: Getting to know eachother.
Hallo, hoe gaat het met jou?
Hello, how are you doing?
Hallo= Hello
Hoe gaat het met jou= how are you doingjou= you
hoe= how
het= it
Literally gaat means go/is going. So literally the sentence means: how is it going with you. In dutch however it is said like this.
If you have any requests for me, for example things you want to say in dutch, just send me a message!
