Word of the Week - Iridescent

How do you describe a pearl? It doesn't shine like other gems. Doesn't shimmer, has no fire. It gleams, yes. But it's the rainbow of color that really sets it apart. That . . . you know, the pearlized effect. ;-)  Its iridescence.

I can never think of a more accurate word for it, so I was a little frustrated when I looked up "iridescent" and realized it entered English just a wee bit too late for my 1780 book. As in, 16 years later, in 1796. After grumbling for a minute over not being able to justify using it (I'm nit-picky about my word choices like that), I put it aside to wonder about the word.

"Iridescent" comes from the word "iris." Now, we all know "iris," right? The colored part of our eyes. A flower. Yep. But apparently "iris" means rainbow in Greek--hence why the colored part of our eyes are called that. The Greeks would also use it to describe any colored circle, like the round "eyes" on a peacock feather. Pretty neat, huh?

So it makes perfect sense that we would have created a word like "iridescent" to describe that rainbow effect. If only we had created it two decades earlier . . . ;-)

  1. Fascinating stuff, as always. Can you just move your book a couple decades later? ;)

  2. LOL. Sure, no one will notice if the Revolutionary War is in the wrong decade, right? ;-) Totally worth it to be able to use that word.
