@MSP_SMIMSA Funnily enough, I wrote a short play which our drama group performed at the weekend. I gave one character the word *dissemble* which he changed to *pretend* because he'd never come across it until I told him what it meant. He also had the word *perspicacious* which he changed to *astute* because he couldn't pronounce it without tripping up.
And there I was choosing my words with care.
