The Difference Between?

Working in such a tightly regulated and hugely competitive industry and dealing with technologies that can at times be controversial, I expect to hear heated debates or energetic discussions regarding the nature and/or value of regulations, cutting edge technologies, or free market price wars.  Because of the nature of our industry, I am never surprised when I hear animated exchanges when those topics are on the table.

However, what does continue to surprise me, no matter how many times I witness it, is the sight of a group of peers deep in conversation, debating whether or not there is significance to a word that they chose or did not choose to use or, worse yet, the difference between two words that they mistook for one another.

In my experience, I have found that when this occurs, the words in question are often those that sound alike, but are not alike, or words whose meanings are closely, but often inversely, related.

There are a few pairs of words that large portions of our industrial work force use as though they are interchangeable.  There are still other words, whose meaning is inferred because of the perceived meaning of the partner word.
