Last week, my client and I had a recent discussion about usage of "hone" versus "home" when referring to zeroing in on something. He thought "home" was correct, whereas I was strongly in the "hone" camp. We looked up both words, and as of Friday, he seemed willing to concede that "hone" was correct for our context. Apparently, though, the issue still nagged at him, because I received an email from him this morning chock full of alternate definitions, usage guidelines and commentary from various sources--all arguing for the use of "home" instead of "hone."
Yet it was not the definitions, guidelines and commentary that swayed me--it was the sentence with which he began the email: "'Hone in' has evolved as a common mispronunciation of 'home in'--akin to saying ‘nucular’ instead of 'nuclear.'"
Consider me converted.
