Other forms: emblazoned; emblazoning; emblazons
To emblazon is to decorate something with words or symbols. If you're running for student council, you might emblazon t-shirts with your name and hand them out to your classmates.
The word emblazon means the same thing as the word blazon, “to depict or paint armor.” Both words have roots in the English word blaze, in the sense of “to make public.” No one uses blazon anymore, and these days you can emblazon anything—not just armor! Colleges and universities frequently sell sweatshirts and hats emblazoned with their logos, for example.
