When I spell my name, I usually say it's "Marie" with "ke" behind it. (My name is Marieke, I'm from Holland). Is this correct? I just think of it as the first letter of a word is in front so the following letters are "behind", however my husband disagrees. I could well be wrong as English is not my first language. Can you help?
From a native Chicagoan living in Brooklyn, NY, I recommend addressing an English speaker with:
It starts with Marie, M - A - R - I - E then K- E.
Note how I used the word "then" in my delivery. So you can rely on the listener to know how to spell "Marie" as you mention in your question. Nice name, btw!
I would say, "My name is Marieke. It is spelled like Marie and then a K and E at the end."
I am assuming two things. That in your culture the name Marie is common and it is pretty much always spelled M A R I E (and it is pronounced the same). And that you give them your full name first so that they have context.
