In last month's column, I wrote about variety in word formation processes, the phenomenon of having more than one word form lo represent the same concept, illustrated by word pairs like analysis/analyzation, summary/ summarization, and intensity/intenseness. There is, of course, the other side of the coin. We also use single word forms to represent an array of meanings.
