This is one used by the well educated and the undereducated alike. I have seen it commonly used on social networks, in common everyday conversation, in many online forums, but it is most disheartening when I find it in professionally edited and published books, unless the author indended for a character to misuse the term in dialog. And even in that case it's a lame excuse.
Hone can be used as a noun or a verb, but is most often misused as a verb. I'm guessing that the misuse of this word is because it is only one letter off the correct word, and therefore can be easily confused when heard in in speech.
Hone: Noun:
1. A whetstone with a fine abrasive texture used for sharpening razors, knives and other sharp tools.
2. A precisoin tool used to bore or enlarge holes to exact dimensions.
Hone: Verb:
1. To sharpen on a hone (whetstone):
He honed his knife.
2. To bore, enlarge or finish a hole with a hone.
3. To make more effective or acute, to sharpen, improve or perfect one's skills.
The lawyer honed her argument.
And definitions that have fallen out of usage:
1. Followed by
for or
after: To yearn or pine: He honed after the life on the farm he left behind;
She honed after a piece of homemade pecan pie.
(This usage is found more in the Southern United States.)
2. To moan or grieve:
She honed for her stilborn child.
Used incorrectly where the word
home is meant: This device makes it easier to
home in (
not hone in) on the target.
The Correct Usage:
Home: Noun: This context only:
1. Target, goal.
Home: Verb:
1. (Of guided missiles, aircraft, etc.): To proceed, especially under the control of an automatic aiming mechanism toward a specific target; usually followed by in on:
The missile homed in on the target.
Homing: Adjective:
1. Capable of returning home, usually over a great distance, as a
homing pigeon.
2. Guiding or directing homeward or to a specific location, as a
homing instinct, or
homing device.
It grates to hear or read about a person "honing in on" a particular place or thing, especially when there are no sharp objects in sight. Not even a wit.
