There's a word for that...

[lisamoe]

I was unaware until today that there is a term for the common usage of an incorrect word in place of a similar sounding word. Like using "quickclaim deed" for "quitclaim deed" or "hone in on" for "home in on." Apparently, the word for this is eggcorn, from a misapprehension of the word "acorn." I think it also applies to things like "with baited breath" instead of "with bated breath" where it's written incorrectly even though it sounds the same when you say it out loud.

A few that come to mind that I hear/read sometimes are "for all intensive purposes" rather than "for all intents and purposes," "upmost" for "utmost," and "tow the line" for "toe the line."

It really gets my dander up, as opposed to getting my dandruff up, as it apparently does some folks. ;-)
