It's "Nurse!"

I don't know why I keep encountering this pronunciation error. When I come in contact with Filipina nurses trying to work abroad, many of them say, "I am a nurst." I always wonder where the "t" sound is coming from as it's obvious that the word ends with an "s" and not a "t."

Anyone care to offer a theory about why this error happens?

Sometimes, I think it's the stress. Nurses have to cope with so much in order to work abroad that some mistakes are liable to be made along the way.

It's not "nurst," it's "nurse!"

I hope nurses read my blog.
