Do you use pretty words??

One day I was sitting here...editing...hubby was on the adjacent couch watching some TV (probably UFC...ewwwwwww). I needed a different word for ivory. So I pulled up my favorites and went to www.dictionary.com...my most used word site. I typed in 'ivory' and clicked thesaurus. In 2.5 seconds, I had tons and tons of words that meant ivory. One jumped out: nacreous.

I made a comment and hubby asked what I was talking about, so I told him. His response: Why would you use that? No one will know what that means.

In the end, I agreed and went with something else. But it made me wonder.....as writers, do we often use words for their beauty on the page and the sound they make rather than if they are really the right word to get out point across to the reader?? Cause in the end, it's the reader that matters, right??? And how many people out there would know what 'nacreous' means? I know what it means now, but before I typed 'ivory' into my thesaurus, did I?? No. There was probably a way to add in my pretty word and use surrounding text to let the reader know what the word meant...but why confuse the reader and make them have to reread the sentence?

I've read pieces where it seemed like the writer took a thesaurus and replaced every word in the piece with the most ostentatious word they could find. Are writers who do that just trying to show off...make themselves look like a really fantastic writer??? I don't know. For me, the bottom line...if my reader can't understand what my story is about....it is a failure.
