wee-uh-TEN-on
Here's a breakdown:
* wee: The "ui" combination sounds like "wee"
* uh: The "a" is a short, unstressed vowel sound, similar to the "a" in "about."
* TEN: The "ten" is pronounced as in the number "ten."
* on: The "on" is pronounced as in the word "on."
It's a bit of a tongue twister, but with practice, you'll be able to say it like a pro!
