Marker Word
Quick answer
A specific word, often "yes," used the same way a clicker is, to mark the exact instant a dog does the right thing.

What it means
A marker word functions as a bridge without needing to carry a physical clicker, though it's typically slightly less precise since a spoken word's timing and tone can vary more than a clicker's consistent sound. Whichever is used, it has to be taught first (paired with a reward repeatedly) before it carries any meaning to the dog.
A real example
A trainer says "yes!" the instant a dog's paw touches a target, then delivers a treat a second later, the same mechanism as a clicker.
Common mistake
Using the marker word in normal conversation as well ("yes, good boy, yes you are"), which dilutes its precision as a training signal.
