I have a decent vocabulary but often hesitate to use some words lest I confuse readers or people I am talking to. Unfortunately, in my opinion, some writers gravitate toward words that confuse many readers. I can rationalize the use of some, "Way out there" words if you are writing poetry and need a word that rhymes. I keep a dicitionary handy while reading. I use spell check when writing, not so much to correct mispellings as to correct typing errors. Last night I did a little reading where I didn't have easy access to a dictionary. In one short chapter I found six words that seemed ill chosen. I was more put off by the words than confused. I absolutely knew the meaning of "Legerdemain" and "Prescient." I stumbled over "Percutaneous" but recognized the cutaneous part and deduced the rest. I drew an absolute blank with "Tenebrous." I didn't have a problem with "Pellucid" or "Nacreous" but I'll bet many people would. My question is, why not use words that are understood by 99% of readers rather than use words that confuse 50%? Sometimes I thnk it is an ego thing.
