OK. I can ask now. What's the view on yesterday's answer - snafu. I know what it means but surely this is an acronym rather than a word?
I may have learned something. Apparently in modern language we "initialisms," for example YMCA, PTSD and "acronyms" which are words created out of initials, for example scuba, aids. I've never thought of an acronym as a word.
I wonder if we would have questioned "scuba?"
