Well, Dermot, according to my dictionary Iron is correct in saying enunciation...1.To pronounce; esp. with clarity; articulate. Pronounciation is 1. To utter. Makes for a confusing world when we can't even depend on dictionaries to agree.
Four years in college studying speech therapy taught me that enuciation means to speak clearly, give each letter in the word a voice.
Four years in high school choir, I was taught the same as Cathy. You don't chop off the end of a word. My choir director would make a spectacle of any one of us if he caught us "getting lazy", as he would call it, with the lyrics.
That is one of the things that stuck with me and one of the technical things that I admired about Gord.
