Precision and Accuracy

Often either of two words will suffice in a sentence, but the shades of meaning differ. There is, for example, a difference between saying that a doctrine is old and saying that it is venerable, between calling a treatise compendious and calling it voluminous, and between characterizing a person as drunken as opposed to merely drunk on a specific occasion.

Careful writers make distinctions. They cultivate an awareness for words and their connotative differences. They would no more write incidental to when they mean incident to than a carpenter would try to nail with the handle of a screwdriver.
