...a last name that consists of 2 letters, N and G? Basically, "Ng". No vowels.

Why? There is a guy that is going to help students tour the department I'm interested in going next year. He has that last name, and it's not a misspelling if you are thinking that. He was born in Hong Kong and he's a senior with experience in the department. I need to meet up with him.

So, I'm thinking "Ng" might sound .. something similiar to "Nug"?

I have a friend who has the same last name, they pronounce it "Ing"

It's like "eng", but with a silent "e".

We say "Ung"

Engee

My main reference on this issue, Ana Ng by They Might Be Giants:

[the portion of the song where you first here the name Ana Ng is ~40 seconds into the song.]

"New"

I had a Vietnamese friend with that last name.

Edit: This would be irrelevant considering, your dude is from HK. Probably different pronunciation.

Ung. just try not to pronouce the U much.

The viet pronounciation is "nyu"

Assuming it's Cantonese (Hong Kong...), "ng" is "ŋ" in the IPA, so, think about the "ng" in "sing" or "ring."

Pronounce it "boink". That will surely impress him.

Heh, or not...

That's exactly what I was thinking.

It appears my first guess was off.

Judging from the thread respones, it seems there are some going for something sounding similar to "ing (or ung)" and others going for "new"?

Roach is right in this context.

oh IPA. The only reason I said th "U" was because my friend went on a college visit a few years ago and had a lesson with a professor "Ng" pronounced "Ung" but it's probably not the same...anything

Saying "ng" like in 'sing' seems kinda silly, though. Lolarz

This is how you say it:

"Un-American".
