I wonder if your remuneration problem may be similar to my
verisimilitude problem. I think it's a wonderful word, but I've never used it in conversation; I just can't get my tongue around it.
I have a similar problem with
corollary - every time I try to say it out loud I am reminded of Pratchett: "Nanny Ogg knew how to start spelling 'banana', but didn't know how you stopped." I try to say corollary and end up with too many "oro"s in there somewhere. ... Maybe that's why I like reading so much, all these wonderful words that don't have to be spoken.
