I myself have been guilty of being prolix at times. Perhaps anyone who isn't a mute has had a moment of prolixity. At least, for the most part, I am aware of my prolix moments, and knowing I have so many words I need to or want to expel in order to explain myself or tell a story, I always find myself speeding up. The longer my speech, the quicker I speak.
If I take a deeper look into the meaning of prolix though, I wonder if giving a simple explanation, even though it may require a plethora of words, I wonder if it is truly verbose. If I explain something without an excess of words, despite the fact that I may go on for five minutes, is it unduly prolonged?
But then if we look at it from the view of anything that is too long, then anything could be considered prolix, depending on many different points of view. At some point, anyone could find anyone extremely or even minutely prolix.
But alas, looking back at this posting, I think I may have just been a bit prolix.
