I came across a story (which Google, alas, was unable to locate) how Faulkner supposedly didn’t keep a dictionary at home. And so whenever he had to look something up, he’d take a walk down to the drugstore in town, which luckily kept a dictionary on hand for him to use. The writer suggested this may explain Faulkner’s occasionally idiosyncratic use of some words—usage that, while at times may have been incorrect, coming as it does from a Nobel laureate, nevertheless altered the dictionaries he didn’t have.
