Word of the Day: Deuteranopia

deuteranopia
noun. kind of colour blindness: colour blindness in which red and green are confused. Also called red-green colour blindness.

On one of the mailing lists I monitor, someone incorrectly used it to describe all forms of colour blindness. Bad technical writer, bad!

The prefix deutero refers to second or secondary. I was also pleased to learn a new word: deuteragonist, which means the ‘second most important character: a character second in importance to the leading character (protagonist) in ancient Greek drama’.
