When perusing woodworking articles online, I often read about dado joints made with dado cuts using dado blades.

Each time I come across the word dado, I pronounce it differently and it's starting to bug me. Which is the correct way to pronounce dado? Is it:
- dado like dad
- dado like dot
- dado like date
